Every time you board a plane, there are countless safety systems working behind the scenes to protect you, many of which you might not even notice—cleverly placed components with details specifically created to minimize risk and ensure a smooth journey. Here are 15 airplane safety features you probably never knew existed but might be the reason you survive a crash.

Enhanced Vision Systems (EVS)

Enhanced Vision Systems (EVS) come to the rescue when visibility is low and give pilots a clearer view in certain situations. Using infrared cameras, EVS captures thermal images of the runway and surrounding areas, which allows pilots to land safely even in thick fog or at night. 

Emergency Evacuation Slides

Emergency Evacuation Slides are efficient and make evacuation fast. These slides inflate almost instantly and provide a safe, rapid exit for passengers in emergency situations. Passenger slides are designed to safely handle the weight and speed of passengers during descent. 

Tail Strike Protection

Tail strikes are a serious risk during takeoff or landing where the tail touches the ground, causing damage if not properly managed. Sensors on the aircraft’s tail monitor its distance from the runway, and If the sensors detect the tail getting too close, warnings alert the pilots to adjust the aircraft’s pitch immediately. 

Windshield Heaters

Clear visibility in cold weather wouldn’t be possible without windshield heaters. They work to keep ice and frost from accumulating on the cockpit windshields and ensure that pilots can see clearly during takeoff and landing. Windshield heaters help reduce the risk of accidents caused by poor visibility.

Flameless Venting System

When there’s a fuel tank explosion, the Flameless Venting System stands between disaster and safety. This system rapidly vents excess pressure without allowing flames to escape, which minimizes the risk of fire spreading through the aircraft. The technology ensures that any sudden pressure buildup is safely managed.

Hydraulic Fuses

Aircraft hydraulic systems control key functions, and Hydraulic Fuses ensure they keep working even when things go wrong. Designed to seal off any damaged hydraulic lines automatically, they prevent the loss of hydraulic fluid and keep critical systems, like brakes and landing gear, operational.

Crash-Resistant Seats

Aircraft seats aren’t just for comfort—Crash-Resistant Seats are made to protect passengers during emergencies. These seats absorb impact energy and reduce the forces passengers feel during a crash. The materials and engineering behind these seats aim to lower the risk of injury during turbulence or accidents.

Cabin Smoke Detection

Modern airplanes are equipped with super-sensitive Cabin Smoke Detection systems that can spot a fire risk before it becomes a big problem and cause a fatal accident. The detectors keep an eye on the air in the cabin and other areas, letting the crew know right away if there’s any smoke.

Smoke Hoods and Fire Gloves

When there’s a fire onboard, the crew uses Smoke Hoods and Fire Gloves to get close enough to the source to put it out. Smoke hoods keep the crew from inhaling harmful fumes, while the heat-resistant gloves let them handle hot materials. They are stored near crew seats for easy access.

Stowage Latches

Securing heavy items on a plane is important for the safety of passengers and the aircraft. Stowage latches are key in ensuring that storage compartments and contents stay secure, especially during turbulence. These locks prevent heavy objects from coming loose and causing harm to passengers or damage to the aircraft.

Defibrillators

Medical emergencies happen, and Defibrillators on board give the crew a fighting chance to save lives. In the event of a heart attack, the crew is trained to use the defibrillator to administer a life-saving electric shock. A defibrillator on every flight ensures immediate care can be provided in emergencies.

Pneumatic Cylinders on Main Cabin Doors

Aircraft main cabin doors are equipped with Pneumatic Cylinders to help open them swiftly during emergencies. These gas-powered actuators push the heavy doors open and ensure passengers can evacuate quickly. The system works against gravity and makes it easier to open the doors in critical situations.

Indicators on Wings Detecting Icing

Icing on wings can pose flight risks, but indicators on wings detect icing and help activate the anti-ice system automatically. They are sensors that trigger the release of hot air onto the wing surfaces, melting any ice that may have accumulated. Ice buildup can severely compromise a plane’s lift

Bleed Hole on Windows

Among the lesser-known safety features, the Bleed Hole on windows is key to maintaining cabin pressure. These tiny holes allow for the equalization of pressure between the cabin and the space between the window panes. By preventing pressure buildup, they ensure the window remains intact despite sudden depressurization.

Floor Proximity Emergence Escape Path Marking System 

The FPEEPMS is designed to help guide passengers, especially during emergencies or when it’s hard to see in the dark. This system uses light-up markings on the floor to show the quickest way to the exits so that everyone can get out of the aircraft fast and safely.
