What Is A Passive Safety Feature
As technology advances, the automobile industry continues to strive to make cars and trucks safer. Ever since the invention of the motorized vehicle, manufacturers have attempted to make it safer for drivers and passengers. But as the car and truck accident statistics show each year, we still have a long way to go.

There are still too many people being seriously injured or killed in car accidents every year on our roads and highways. But every year, newer model vehicles become safer. For most of the history of the automobile, car designers focused on passive safety devices and systems. However, over the past few decades, the focus has been to incorporate active safety features, devices, and systems into the design of new vehicles.

A passive safety feature is any safety system that reacts to a collision and attempts to keep occupants safe, but only after a collision occurs. Active safety features are those that attempt to avoid collisions altogether.

What is an example of a passive safety feature?

What are active car safety features? – Active car safety features are on the cutting edge of road safety technology. These safety measure are designed and implemented to prevent accidents before they happen. They typically harness emerging technologies to grant drivers greater awareness.

Automatic emergency braking. The car will detect a slow-down or stop in traffic ahead and alert the driver. If the driver takes no action, the brakes will slow the vehicle down gradually. Forward collision warning. This technology is similar to automatic emergency braking. It will alert the driver to danger, but will not automatically apply the brake. Adaptive cruise control. ACC allows drivers to set the speed limit, just like normal cruise control. However, this technology responds to other road users, braking when necessary to mirror the traffic around it. Lane departure warning. This technology stops drivers from drifting over into other lanes. Some instances of the technology can even help the driver avoid gutters and drains. Lane-keeping assist. This technology is similar to the above mentioned LDW. LKA goes a step further in helping the driver stay in the right lane by steering the car for up to 40 seconds. Blind spot monitoring. Another handy awareness tool, this technology actively monitors the blind spot over the shoulder, reporting hazards with a warning light. Rear-cross traffic alert. A boon for parents and toddlers. This technology allows drivers to more effectively reverse out of car parks and driveways.

Active safety measures are highly developed and rigorously tested. To receive a 5-star AANCAP safety rating, vehicles need to possess most of the above mentioned features. What are passive car safety features? Passive car safety features are safety measures included in the vehicle to aid passengers in the event of the crash.

Airbags that deploy when the car rapidly decelerates beyond braking speedSeatbelts which lock into place, preventing passengers from ejection and impactThe structure of the car, fitted with crumple zones and high strength glass

All the technology in the world cannot prevent tragedy — it’s a fact of life that some accidents are simply unavoidable. However, if your car possesses high-quality passive safety measures, you and your passengers will be far more likely to survive a serious road incident.

  • In summary, passive and active safety measure work in tandem to keep you safe.
  • Neither category is more important than the other — they just come into play at different times.
  • In the end, road safety comes down to you.
  • Do your best to protect your family by driving to the speed limit, with alertness, and full focus on the road ahead.

What is the meaning of passive safety features?

More Protection at the Right Moment – Every day, accidents happen on the roads where the risk of serious accidents can be reduced thanks to passive vehicle safety. Modern aids not only provide support during driving; they also contribute to the safety of the occupants.

What is the example of active safety and passive safety?

From Wikipedia, the free encyclopedia The term active safety (or primary safety ) is used in two distinct ways. The first, mainly in the United States, refers to automobile safety systems that help avoid accidents, such as good steering and brakes. In this context, passive safety refers to features that help reduce the effects of an accident, such as seat belts, airbags and strong body structures.

  • This use is essentially interchangeable with the terms primary and secondary safety that tend to be used worldwide in standard UK English.
  • The correct ISO term is “primary safety” (ISO 12353-1).
  • However, active safety is increasingly being used to describe systems that use an understanding of the state of the vehicle to both avoid and minimise the effects of a crash.

These include braking systems, like brake assist, traction control systems and electronic stability control systems, that interpret signals from various sensors to help the driver control the vehicle. Additionally, forward-looking, sensor-based systems such as advanced driver-assistance systems including adaptive cruise control and collision warning/avoidance/mitigation systems are also considered as active safety systems under this definition.

These forward-looking technologies are expected to play an increasing role in collision avoidance and mitigation in the future. Most major component suppliers, such as Aptiv, TRW and Bosch, are developing such systems. However, as they become more sophisticated, questions will need to be addressed regarding driver autonomy and at what point these systems should intervene if they believe a crash is likely.

In engineering, active safety systems are systems activated in response to a safety problem or abnormal event, Such systems may be activated by a human operator, automatically by a computer driven system, or even mechanically. In nuclear engineering, active safety contrasts to passive safety in that it relies on operator or computer automated intervention, whereas passive safety systems rely on the laws of nature to make the reactor respond to dangerous events in a favourable manner.

What is passive safety electronics?

Front Impact – Passive Safety sensors for frontal collisions are accelerometers that determine through the measurement of deceleration forces whether there has been a serious enough rapid change in the vehicles movement to warrant the deployment of passive safety devices such as seat pretensioners and airbags.

  • The accelerometers are connected to computer chips and software programs that evaluate the accelerometer input data and then determine if a deployment of the safety devices is needed.
  • This process of measuring data and calculating a decision to deploy varies by vehicle, but generally must be done in under 20 mili-seconds.

This is one of the most difficult processes to be done in the time frame. Passive Safety Electronic Control unit and accelerometers

What are 3 passive safety features used in a vehicle?

Active and passive automotive safety systems Passenger safety occupies a prime spot in the automobile sector today. Stakeholders across the automobile value chain acknowledge the importance of passenger/occupant safety and are constantly upgrading their offerings to provide fail safe safety technologies that will protect passengers and pedestrians.

Proactive policy implementation and consumer awareness has played a key role in making automotive safety systems popular. Author: Atul Kumar, Team Lead (Automotive & Transportation Domain), MarketsAndMarkets However the penetration of these lifesaving technologies differs from country to country. Economically developed countries tend to have a high penetration of these technologies across various passenger and commercial vehicle segments.

Traditionally Automobile Safety Systems can be classified in to two segments, namely Active Safety Systems and Passive Safety Systems. Active Safety Systems as the term suggests play a preventive role in mitigating crashes and accidents by providing advance warning or by providing the driver with additional assistance in steering/controlling the vehicle. Head-Up Display (HUD), Anti-Lock Braking Systems (ABS), Electronic Stability Control (ESC), Tire Pressure Monitoring System (TPMS), Lane Departure Warning System (LDWS), Adaptive Cruise Control (ACC), Driver Monitoring System (DMS), Blind Spot Detection (BSD) and Night Vision System (NVS) are common Active Safety Systems.

  1. Passive Safety Systems play a role in limiting/containing the damage/injuries caused to driver, passengers and pedestrians in the event of a crash/accident.
  2. Airbags, Seatbelts, Whiplash Protection System etc.
  3. Are common Passive Safety Systems deployed in vehicles these days.
  4. An emerging trend witnessed in the global automotive safety system market is the increasing demand from the countries like India, China, Russia and Brazil.

Since the market for the safety systems like Airbags and ABS in developed economies is maturing and becoming saturated, OEMs and suppliers are focusing on increase demand from emerging markets. The demand is becoming higher in emerging markets primarily because of the improving road safety standards/supporting legislation and consumer awareness.

Active safety systems: Passive safety system:

Head up display: The automotive HUD finds application in the majority of the passenger car segments. Given the increasing adoption of HUD in the automotive sector, it has become a standard feature for various models in the luxury car segment. Additionally, the increasing demand for comfort and safety has compelled automakers to incorporate this feature in premium and mid segment models as well.

  • The market in growing regions such as Asia-Pacific, and North America indicate promising growth potential for the automotive HUD market.
  • The Asia-Pacific automotive market in particular presents high-growth opportunities; the region includes Japan, China, and India, with the latter two having huge production capabilities.

The European HUD market is primarily driven by the growing awareness regarding driver safety and convenience. Europe has many luxury/premium car manufacturers. Major high-end car OEMs such as Audi AG (Germany), BMW (Germany), Mercedes-Benz (Germany), Bentley Motors (UK), Maserati (Italy), Ferrari (Italy), and Bugatti Automobiles (France) have their headquarters in Europe.

  • The automotive HUD comes as standard safety feature in the majority of European automobiles.
  • The region therefore has a wide customer base for this technology.
  • Windshield head up display technology and combiner head UP display technology The windshield head up display projects a virtual image with the necessary information needed by the driver.

This information is projected in accordance with the drivers eye gaze. In this technology type, the windshield of the car plays an important role as there are chances that the image produced by the device can be distorted. The conventional HUD uses TFT displays which projects images on the windscreen.

  1. With the advancement in technology there have been improvements in the display technology.
  2. One of the differentiating factors between the two types of HUDs is the space requirement and image resolution.
  3. The Combiner HUD type has a smaller screen which displays the necessary information but lacks the picture quality as compared to the other type.

The Combiner HUD has an adjustable positioning system which enables the driver to adjust the screen according to their convenience. Augmented Reality head up display technology Augmented reality (AR) is an upcoming trend in the head-up display market. Augmented HUD is a real time technology which enhances the safety and driving experience. Augmented reality-based HUD technology provides full-colour advanced driver assistance system (ADAS) including lane departure warning system and advanced driving information.

The AR-HUD sense the exterior environment of the vehicle, analyses this information and virtually display the traffic condition. For example, if the driver has set a destination on the navigation system, the AR-HUD projects a virtual route that is to be followed. It also detects the distance between itself and the vehicle in front and alerts the driver.

The differentiating factor for AR-HUD is that it projects information which appears to be part of the driving situation itself. : Active and passive automotive safety systems

What are passive and active safety features?

As technology advances, the automobile industry continues to strive to make cars and trucks safer. Ever since the invention of the motorized vehicle, manufacturers have attempted to make it safer for drivers and passengers. But as the car and truck accident statistics show each year, we still have a long way to go.

There are still too many people being seriously injured or killed in car accidents every year on our roads and highways. But every year, newer model vehicles become safer. For most of the history of the automobile, car designers focused on passive safety devices and systems. However, over the past few decades, the focus has been to incorporate active safety features, devices, and systems into the design of new vehicles.

A passive safety feature is any safety system that reacts to a collision and attempts to keep occupants safe, but only after a collision occurs. Active safety features are those that attempt to avoid collisions altogether.

What is passive vs inherent safety?

Terminology – ‘Passive safety’ describes any safety mechanisms the engagement of which requires little or no outside power or human control. Modern reactor designs have focused on increasing the number of passive systems to mitigate risk of compounding human error.

  • Despite the increased safety associated with greater coverage by passive systems, all current large-scale nuclear reactors require both external (active) and internal (passive) systems.
  • There are no ‘passively safe’ reactors, only systems and components.
  • Safety systems are used to maintain control of the plant if it goes outside normal conditions in case of anticipated operational occurrences or accidents, while the control systems are used to operate the plant under normal conditions.

Sometimes a system combines both features. Passive safety refers to safety system components, whereas inherent safety refers to control system process regardless of the presence or absence of safety specific subsystems. An example of a safety system with passive safety components is the containment vessel of a nuclear reactor.

  1. no moving working fluid
  2. no moving mechanical part
  3. no signal inputs of ‘intelligence’
  4. no external power input or forces

In category A (1+2+3+4) is the fuel cladding, the protective and nonreactive outer layer of the fuel pellet, which uses none of the above features: It is always closed and keeps the fuel and the fission products inside and is not open before arriving at the reprocessing plant.

In category B (2+3+4) is the surge line, which connects the hot leg with the pressurizer and helps to control the pressure in the primary loop of a PWR and uses a moving working fluid when fulfilling its mission. In category C (3+4) is the accumulator, which does not need signal input of ‘intelligence’ or external power.

Once the pressure in the primary circuit drops below the set point of the spring-loaded accumulator valves, the valves open and water is injected into the primary circuit by compressed nitrogen. In category D (4 only) is the SCRAM which utilizes moving working fluids, moving mechanical parts and signal inputs of ‘intelligence’ but not external power or forces: the control rods drop driven by gravity once they have been released from their magnetic clamp.

  1. But nuclear safety engineering is never that simple: Once released the rod may not fulfil its mission: It may get stuck due to earthquake conditions or due to deformed core structures.
  2. This shows that though it is a passively safe system and has been properly actuated, it may not fulfil its mission.
  3. Nuclear engineers have taken this into consideration: Typically only a part of the rods dropped are necessary to shut down the reactor.

Samples of safety systems with passive safety components can be found in almost all nuclear power stations: the containment, hydro-accumulators in PWRs or pressure suppression systems in BWRs. In most texts on ‘passively safe’ components in next generation reactors, the key issue is that no pumps are needed to fulfil the mission of a safety system and that all active components (generally I&C and valves) of the systems work with the electric power from batteries.

IAEA explicitly uses the following caveat:, passivity is not synonymous with reliability or availability, even less with assured adequacy of the safety feature, though several factors potentially adverse to performance can be more easily counteracted through passive design (public perception). On the other hand active designs employing variable controls permit much more precise accomplishment of safety functions; this may be particularly desirable under accident management conditions.

Nuclear reactor response properties such as Temperature coefficient of reactivity and Void coefficient of reactivity usually refer to the thermodynamic and phase-change response of the neutron moderator heat transfer process respectively. Reactors whose heat transfer process has the operational property of a negative void coefficient of reactivity are said to possess an inherent safety process feature.

  1. An operational failure mode could potentially alter the process to render such a reactor unsafe.
  2. Reactors could be fitted with a hydraulic safety system component that increases the inflow pressure of coolant (esp.
  3. Water) in response to increased outflow pressure of the moderator and coolant without control system intervention.

Such reactors would be described as fitted with such a passive safety component that could – if so designed – render in a reactor a negative void coefficient of reactivity, regardless of the operational property of the reactor in which it is fitted. The feature would only work if it responded faster than an emerging (steam) void and the reactor components could sustain the increased coolant pressure.

What is passive safety of an aircraft?

Safety by Design When it comes to safety, positive results are what really matter most. Diamond has earned a safety record, backed by real world data, that is second to none. Our primary design goal is to build aircraft that are a pleasure to fly, yet forgiving and safe, while offering maximum protection in case of an accident.

  1. To accomplish this, we invest in two key safety strategies, Active and Passive Safety.
  2. DA42-VI Single Engine Service Ceiling: 18,000 ft (5,486 m) – photo taken during a test flight Safety avionics Glass cockpit Garmin G1000 NXiwith integrated autopilot Certified de-icing system The best accident protection is to avoid them in the first place.

Active Safety features and characteristics help do just that. Active Safety refers to all the features and characteristics of an aircraft that help pilots avoid an accident. These include:

  • unparalleled visibility
  • agile yet forgiving flight characteristics
  • continued controllability through a stall
  • positive stability
  • superb runway and climb performance
  • high crosswind capability
  • system and structural redundancy
  • comfortable pilot workload
  • reliable power
  • the latest in avionics technology (integrated glass cockpit and digital autopilot)
  • Beyond that, active safety includes the matching of an aircraft design to its intended mission and pilot capability.
  • Our single engine piston models are especially docile and well suited for expert and novice pilot alike.
  • Our high-performance aircraft offer ice protection and twin engine safety, yet are easy to fly with simple single lever power controls.

Unfortunately, not all accidents can be avoided. Passive Safety features are the second line of defense and help minimize the probability and degree of injuries. Passive safety elements include:

  • structural integrity of the cabin under crashloads
  • effective occupant restraint
  • impact energy absorption
  • unobstructed headstrike zones
  • flammable fluid fire protection

Each Diamond aircraft incorporates an integral cabin surrounding composite “roll cage” structure, which is stiff and strong to provide survival space and protection in case of impact. With the adoption of crashworthy composite cockpits, Formula 1 race car safety evolved from fatal injuries and fires being commonplace to fatalities and fires becoming virtually unknown. Integrated fixed seat shells with energy absorbing crash elements, antisubmarine geometry and three-point shoulder and lap restraints offer effective, yet comfortable occupant restraint which is critical to crashworthiness. Diamond performs dynamic crash tests not only of seats, as is typical, but of the entire fuselage cabin structure to test structure, seats, and restraints as one system. Typical in aviation are light, but fragile, rigid thin-walled aluminum fuel lines. While these tubes are used in many other aircraft, they unfortunately rupture easily in a crash when supporting structures are deformed. To help prevent this, Diamond uses only tough flexible stainless steel braided high-pressure fuel lines that move with the deforming structure and have a vastly superior strength and rupture resistance. Most piston aircraft carry fuel in the wings, but not all are equal in safety. Many use the wing structure, including the vulnerable leading edge as the tank itself, although even very light damage can cause a catastrophic breach. Diamond’s structural design concept was driven by a key goal: protection of the fuel tanks.

  • Our DA62, DA42 and DA40 have a twin wing spar design to allow the fuel to be placed in separate aluminum fuel tanks located between the massive and protective spars.
  • Obviously, this weighs and costs more than merely filling the wing structure with fuel, but it is worth every cent in the added safety it provides.

In the DA20, the fuel cell is extremely well protected by the fuselage safety cell structure, yet separated from the cockpit, reflecting today’s modern automotive practice. Diamond’s designs have achieved an impressive and consistent safety record over many years and millions of hours flown worldwide. Our safety record has been lauded by the aviation press and is rewarded with attractive insurance rates.

  1. Beyond the statistics and insurance rates, safety is about minimizing the risks that are inherent to flying to better protect you and your passengers.

What is the difference between active and passive safety barriers?

Safety barriers – an introduction Safety barriers prevent accidents or limit the consequences of accidents. A safety barrier responds to some adverse condition or an event that, without the barrier, is likely to lead to an accident. Safety barriers can be purely technical systems, or whole or in part involve the actions of humans.

We differentiate between passive safety barriers, such as guard rails and fire walls, and active barriers. We emphasize that active barriers shall be complete, that means that they are able to perform all three actions: Detect the hazardous situation, Diagnose/Decide on the proper response and Act accordingly.

Typical examples of incomplete barriers are alarms, where the response of the operator is not clearly considered. All safety barriers are risk reducing measures, but not all risk reducing measures are safety barriers. We like to call safety measures only for safety barriers if those measures respond “at the sharp edge” to incidents.

That is, the action of a safety barrier is unplanned and unexpected, because the incident comes at unexpected times. All other risk reducing measures, such as maintenance, inspection, providing procedures, training and proper design, are planned activities. These risk reducing measures are important for the success of the safety barrier, but they are normally not included in safety-barrier diagrams.

The present software is able to include these risk reducing measures and also present them in the diagrams as secondary safeguards. We distinguish different types of barriers. A recommended set of barrier types is described in the note “”. For a scientific discussion and definition of safety barriers we refer the list of other publications included on the page.

  1. The barrier is pictured as follows in a,
  2. If the barrier fails, we get the condition on failure (normally the unwanted outcome).
  3. If the barrier functions we get the condition on success – this may be a normal condition that for us – as risk analysts – has little interest, and we may choose not show it.

But functioning barriers can have side effects which we want to analyse as well. Presentation of a safety barrier in a safety-barrier diagram : Safety barriers – an introduction

Are seatbelts active or passive?

Passive Systems Came First – A passive safety system only works when a collision, rollover, or other vehicle upset occurs. Seat belts are a great example of a passive safety system. The lap and shoulder harness helps to keep you and any passengers wearing seat belts secured to your seats.

  1. That restraint helps to stop people from getting thrown from cars or flung forward or to the sides during a violent collision.
  2. Virtually all states have laws that require you to wear a seat belt while traveling in a vehicle.
  3. That seat belt is the first mandated safety feature in any vehicle.
  4. About 60 years ago, seat belts were not mandated by the federal government.

Seat belts were included as standard equipment only on relatively few new cars. And the ones that were included usually only had a simple lap restraint. The Federal Motor Vehicle Safety Standard in 1968 required automakers to include seat belts as standard equipment on all new vehicles.

Is a crumple zone a passive safety feature?

Passive safety features work to ensure that this life space is as safe as possible, and that vehicle occupants remain in this space throughout the crash. Crumple zones help to absorb and distribute crash forces before they reach the passenger and driver’s seats.

Is ABS active or passive safety features?

Anti-lock braking systems (ABS) help prevent the wheels of a vehicle from locking when braking heavily, and enable the driver to keep steering (on slippery roads for example). ABS is one of the key active safety systems that are already widely fitted to today’s passenger cars and commercial vehicles.

What are the disadvantages of passive safety system?

Passive systems make the plant less sensitive to plant equipment malfunctions and erroneous operator actions. The main drawbacks of passive safety systems include the lower driving forces and less possibility to alter the course of an accident if something undesirable happens (i.e., less operational flexibility).

What are the examples of active safety?

In the automotive industry, active safety refers to the Advanced Driving Assistance Systems (ADAS) in a vehicle that help drivers reduce the severity of accidents or avoid them entirely by managing steering, braking and propulsion. Safety has always been of paramount concern in the automotive world.

  1. The industry has developed world-class testing protocols related to vehicle safety, and its advances have been highly successful at reducing the number of traffic fatalities.
  2. The rate of fatalities per 100 million vehicle miles traveled has decreased dramatically over the last few decades, from 3.35 in 1975 to 1.13 in 2018.

The majority of those gains have come from “passive safety” features – that is, features that only activate when an accident occurs and lessen any injury to the driver and passengers. These include seat belts and airbags, as well as structural improvements such as crumple zones that absorb the energy of a crash.

  • However, the gains from passive safety have started to plateau.
  • Additionally, distracted driving has emerged as an increasing issue, partially as a result of smartphones.
  • To continue the trend in improving safety and reach the industry’s goal of zero vehicle-related accidents and fatalities, vehicles have to help drivers stop hitting things.

That is where active safety comes in. By using sensors such as radar, cameras and ultrasonic sensors, a vehicle can perceive the world around it. Processors then interpret that information, acting as a second set of eyes for the driver and taking actions if needed.

Active safety demonstrates clear benefits Relatively simple warning systems such as blind spot detection or forward collision warning have the potential to save lives on their own, but when coupled with a technology that takes action beyond a simple warning to create an active safety system, the results are impressive.

For example, a vehicle could detect if it is approaching an object too quickly, attempt to warn the driver and then apply the brakes automatically if the driver doesn’t respond in time. According to the Insurance Institute for Highway Safety, forward collision warning with automatic emergency braking reduces rear-end collisions by 50%,

This technology has become much more common in recent years as rating agencies such as Euro NCAP put active safety technologies on their testing roadmaps, In the United States, 20 automakers, representing 99% of U.S. light vehicle sales, committed to making the technology standard by 2022, Given that the National Highway Transportation Administration estimates that 94% of all accidents are caused by human error, there are many other opportunities for improvement.

Examples of more advanced active safety systems include features such as automatic lane change, highway assist and traffic jam assist. In these examples, multiple sensors around the vehicle must be integrated through sensor fusion, so that powerful domain controllers running advanced software algorithms can process the information and make driving decisions.

  1. While entry-level active safety systems may take a single action, such as braking, these more advanced systems assist the driver with multiple aspects of controlling the vehicle.
  2. For example, they typically will manage steering – to keep the vehicle in a lane or navigate around slower vehicles – while simultaneously managing the vehicle speed to maintain a safe distance from other vehicles and obstacles.

What is an active safety device?

Active systems give the driver more control in dangerous situations. Simply put, active safety systems avoid or mitigate an accident pre-impact – so before it happens or contact is made. They are also known as ‘primary’ safety features.

What is passive security in a car?

A passive alarm turns on automatically. Once the key is removed from the ignition and all the doors to the vehicle are closed, the alarm turns itself on. This function gives the alarm the name ‘passive,’ as the driver does nothing to arm it.

What is safety features?

Safety feature in British English (ˈseɪftɪ ˈfiːtʃə ) noun. a feature of a product, etc, designed to ensure or increase its safety.

What is a primary safety feature?

Primary Restraint Systems – A primary restraint system is your first line of defense in an accident. It is designed to protect you from the initial impact of a collision. The most common primary restraint system is the seatbelt. A seat belt restraints your upper body and keeps you from being ejected from the vehicle when properly worn.

What’s the difference between active and passive restraints?

Written on March 3, 2008 at 5:25 pm, by Eric Cressey I’m of the belief that all stress on our systems is shared by the active restraints and passive restraints. Active restraints include muscles and tendons – the dynamic models of our bodies. Passive restraints include labrums, menisci, ligaments, and bone; some of them can get a bit stronger (particularly bone), but on the whole, they aren’t as dynamic as muscles and tendons.

Now, if the stress is shared between active and passive restraints, wouldn’t it make sense that strong active restraints with good tissue quality and length would protect ligaments, menisci, and labrums (and do so through a full ROM)? The conventional medical model – whether it’s because of watered-down physical therapy due to stingy insurance companies or just a desire to do more surgeries – fixes the passive restraints first.

In some cases, this is good. For instance, if you have an acromioclavicular joint separation with serious ligament laxity, you’ll likely need surgery to tighten those ligaments up, as the AC joint is an articulation without much help from active restraints.

  1. In other cases, it does a disservice to the dynamic ability of the body to protect itself with adaptation.
  2. Consider the lateral release surgery at the knee, where surgeons cut the lateral retinaculum on the outside of the knee, allowing the patella to track more medially.
  3. I’ve seen a lot of people avoid the surgeries (and, in turn, the numerous possible complications) with even just 2-3 weeks of very good physical therapy focusing on the active restraints.

I’m not saying all these surgeries are contraindicated – just that we need to exhaust other options first. So, the next time you’ve got an ache or pain, consider whether it’s an active or passive restraint giving you problems – and if it’s the latter, work backward to find out which active restraint you need to bring up to par.

What are passive safety features nuclear?

From Wikipedia, the free encyclopedia Passive nuclear safety is a design approach for safety features, implemented in a nuclear reactor, that does not require any active intervention on the part of the operator or electrical/electronic feedback in order to bring the reactor to a safe shutdown state, in the event of a particular type of emergency (usually overheating resulting from a loss of coolant or loss of coolant flow).

Such design features tend to rely on the engineering of components such that their predicted behaviour would slow down, rather than accelerate the deterioration of the reactor state; they typically take advantage of natural forces or phenomena such as gravity, buoyancy, pressure differences, conduction or natural heat convection to accomplish safety functions without requiring an active power source.

Many older common reactor designs use passive safety systems to a limited extent, rather, relying on active safety systems such as diesel powered motors. Some newer reactor designs feature more passive systems; the motivation being that they are highly reliable and reduce the cost associated with the installation and maintenance of systems that would otherwise require multiple trains of equipment and redundant safety class power supplies in order to achieve the same level of reliability.

What is passive safety of an aircraft?

Our primary design goal is to build aircraft that are a pleasure to fly, yet forgiving and safe, while offering maximum protection in case of an accident.

  1. To accomplish this, we invest in two key safety strategies, Active and Passive Safety.

Active Safety features and characteristics help do just that. Active Safety refers to all the features and characteristics of an aircraft that help pilots avoid an accident. These include:

  • unparalleled visibility
  • agile yet forgiving flight characteristics
  • continued controllability through a stall
  • positive stability
  • superb runway and climb performance
  • high crosswind capability
  • system and structural redundancy
  • comfortable pilot workload
  • reliable power
  • the latest in avionics technology (integrated glass cockpit and digital autopilot)
  • Beyond that, active safety includes the matching of an aircraft design to its intended mission and pilot capability.
  • Our single engine piston models are especially docile and well suited for expert and novice pilot alike.
  • Our high-performance aircraft offer ice protection and twin engine safety, yet are easy to fly with simple single lever power controls.

Unfortunately, not all accidents can be avoided. Passive Safety features are the second line of defense and help minimize the probability and degree of injuries. Passive safety elements include:

  • structural integrity of the cabin under crashloads
  • effective occupant restraint
  • impact energy absorption
  • unobstructed headstrike zones
  • flammable fluid fire protection

Each Diamond aircraft incorporates an integral cabin surrounding composite “roll cage” structure, which is stiff and strong to provide survival space and protection in case of impact. With the adoption of crashworthy composite cockpits, Formula 1 race car safety evolved from fatal injuries and fires being commonplace to fatalities and fires becoming virtually unknown. Integrated fixed seat shells with energy absorbing crash elements, antisubmarine geometry and three-point shoulder and lap restraints offer effective, yet comfortable occupant restraint which is critical to crashworthiness. Diamond performs dynamic crash tests not only of seats, as is typical, but of the entire fuselage cabin structure to test structure, seats, and restraints as one system. Typical in aviation are light, but fragile, rigid thin-walled aluminum fuel lines. While these tubes are used in many other aircraft, they unfortunately rupture easily in a crash when supporting structures are deformed. To help prevent this, Diamond uses only tough flexible stainless steel braided high-pressure fuel lines that move with the deforming structure and have a vastly superior strength and rupture resistance. Most piston aircraft carry fuel in the wings, but not all are equal in safety. Many use the wing structure, including the vulnerable leading edge as the tank itself, although even very light damage can cause a catastrophic breach. Diamond’s structural design concept was driven by a key goal: protection of the fuel tanks.

Our DA62, DA42 and DA40 have a twin wing spar design to allow the fuel to be placed in separate aluminum fuel tanks located between the massive and protective spars. Obviously, this weighs and costs more than merely filling the wing structure with fuel, but it is worth every cent in the added safety it provides.

In the DA20, the fuel cell is extremely well protected by the fuselage safety cell structure, yet separated from the cockpit, reflecting today’s modern automotive practice. Diamond’s designs have achieved an impressive and consistent safety record over many years and millions of hours flown worldwide. Our safety record has been lauded by the aviation press and is rewarded with attractive insurance rates.

  1. Beyond the statistics and insurance rates, safety is about minimizing the risks that are inherent to flying to better protect you and your passengers.
  2. Shouldn’t safety be at the very top of your list when selecting your next aircraft?

What is an example of passive restraint?

A passive restraint is any device, such as an air bag, that operates automatically to prevent you being thrown out of the seat of a vehicle if there is a crash. Passive restraints such as air bags or automatic seat belts are required in all vehicles.
