How does an evacuation slide work?
Slides inflate with an initial boost from a canister of compressed carbon dioxide and nitrogen. The canister provides only about one-third the volume needed to inflate the slides. The remaining volume is supplied by ambient air, channeled into the slides through aspirators.
How much does an evacuation slide cost?
It might seem like a laughing matter, but not to the airline that has to repay to replace the slide. Business Insider reports that the stunt could come with a tab as high as $30,000.

What is emergency slide airplane?
Emergency Escape Slides Evacuation slides are single- or dual-lane inflatable slides kept tucked inside cabin doors and external fuselage compartments to provide an alternate aircraft escape method. These devices are used when standard exits are deemed unusable due to water, fire or other safety hazards.
Why are escape slides accidentally deployed?
An accidental deployment of an evacuation slide can occur if the doors have not been correctly disarmed or if there is a malfunction. We’ve all heard the command for the flight attendants to ‘disarm doors and cross-check’ or to ‘prepare the doors for departure/arrival.
Who invented the escape slide?
The first aircraft evacuation slide was developed and produced by Air Cruisers, founded by James F. Boyle, inventor of the World War II life vest, the “Mae West”. The patent for the inflatable escape chute assembly was submitted by Boyle in 1954 and the designs was patented in 1956 under patent number 2,765,131.
How long does it take for an escape slide to inflate?
6 seconds
The slide can be up to 14 metres long. After being fired, the nitrogen power in the bottle will power open the door and the slide pack falls off. Inflation of the slide takes just 6 seconds and some can be up to 14 metres long.
What is girt bar in aircraft?
Methods of arming vary from aircraft to aircraft, but ultimately the girt bar (a metal bar attached to the door end of the slide) is physically attached to brackets either in or adjacent to the door sill.
What is girt bar?
In architecture or structural engineering, a girt, also known as a sheeting rail, is a horizontal structural member in a framed wall. Girts provide lateral support to the wall panel, primarily, to resist wind loads.
How much does a slide deployment cost?
On average, every commercial aircraft will see an inadvertent deployment of at least one emergency evacuation slide. That statistic comes from Airbus’ cabin systems company KID-Systeme, and data from airline trade body IATA suggests that each deployment can cost an airline up to US$200,000.
Who invented the inflatable aircraft escape slide?
Jack Grant
In fact, WLAN technology is estimated to be in more than five billion devices worldwide. CSIRO have a great infogram showing how wifi was invented, on their website. More aircraft innovation! In 1965 Jack Grant, a Qantas operations safety superintendent, invented an inflatable aircraft escape slide.
Does A320 have slide raft?
Airbus Industrie A319, A320, and A321 airplanes that are over-water equipped, like the accident airplane, have a slide/raft at each floor-level emergency exit that is attached to the door by a packboard. Attached to the slide/raft are a fabric girt and telescopic girt bar.
Why do planes have slides?
But that command is integral to the safety of the passengers and crew, preparing a critical device for immediate activation — the plane’s evacuation slides. In the case of an emergency on the ground, inflatable slides deploy from the doors and the wing exits, giving passengers a quick way to escape from an aircraft.
How do you use an evacuation slide?
Evacuation slide in the box at the bottom of the door. There are two types of aircraft evacuation slides: slides and slide/rafts. A slide is for use only on land as a means of escape, although it has sufficient buoyancy to allow passengers to hold on to a lanyard running the length of it and use it as a buoyancy aid.
Who makes evacuation slides for Today Today?
Today Air Cruisers is part of Zodiac Aerospace and ultimately owned by Safran who are the world’s largest provider of evacuation slides. Prior to inflatables, some passenger aircraft utilized canvas type slides which required the crew to undertake an extensive rigging procedure.
What is a stainless-steel evacuation slide?
