Uncontrolled cabin fires only need a few minutes to spread throughout the cabin of an aircraft, killing everyone onboard and destroying the airframe.
Now, we all know that depressurization and fire do not combine; the lack of oxygen will eliminate one of the elements necessary to keep the fire alive. So if an aircraft had a way to depressurize the cabin and eliminate oxygen in the event of a fire, the fire would be extinguished, saving lives. Of course this applies to flights above 14,000 ft. I know that depressurization is dangerous but there is a better chance of surviving a depressurization than surviving flames.
Does a mechanism exist to depressurize the aircraft in case of uncontrolled fire in the cabin? If so, under what circumstances would it be used?
Some aircraft do have a manual decompression button which can be used by the pilot in a situation like this. Keep in mind however that it will only help until the pilot descends (which you will want to do asap in order to land) and the air isn't as thin.
It is very important for the crew to get on the ground as rapidly as possible, and simultaneously attempt to put out the fire in order to minimize the amount of damage that can be done. The single biggest factor in an aircraft fire is how much time elapses before they land and can evacuate.
Also, if the cabin depressurizes, typically the oxygen masks deploy automatically which when combined with a fire can have even more disastourous results.
It takes three things to make combustion - heat, fuel, oxidizer. If you eliminate air, you may not have eliminated the oxidizer if the fire has access to some other oxidizer. While decompression does eliminate some heat (probably not enough), if it's an electrical, self-oxidizing, or metal fire, you're not going to put it out with decompression.
Oxygen-fueled small fires can be put out with a wet cloth (like a wet cotton t-shirt). If the fire is in the engine, most (if not all) commercial planes have built in extinguishers and fuel shut-off, if it's in the baggage compartment, then there's a chance that you're not going to land fast enough to avoid structural failure on or before landing, and decompression won't help because the baggage compartment is already depressurized.

of the pilots can be seen recording the dance on his camera. SpiceJet specially planned this event, and had extra cabin crew on-board the flight as a precaution. Also, during the dance, one of the pilots... was that this was dangerous to flight operations, and could have resulted in disaster had there been any emergency on-board during the event. Also, that this could result in an unruly cabin environment where in-flight safety of the crew and passengers would be affected. Were the actions (suspension of pilots and showcause notice to the airline) justified? Is a dancing cabin crew dangerous
I know the usual scenario is where an airliner suffers from an explosive decompression and the oxygen masks drop and the plane descends to a safer altitude but..... This is a purely hypothetical situation but if a passenger plane was cruising at 39000ft+ and it suffered a cabin leak that somehow went unnoticed by the crew and passengers and the oxygen masks didn't drop, how long roughly would it be before the passengers were incapacitated, and how long before the lack of oxygen became fatal.
We may all be familiar with the part of the cabin safety briefing where they say that, in the event of a reduction in cabin pressure, oxygen masks will drop from a compartment above our heads, yadda yadda, the bag may not inflate. What is the purpose of the bag?
Sometimes, when I'm flying on the airlines, I'll board an aircraft where the aisles seem incredibly cramped, where it's almost impossible to move past without bumping every seat. I can't imagine how much of a nuisance it'd be for people larger than me! I once saw an obese person a bit stuck between one of the aisles, blocking the way for others to move into the aircraft. But then I thought about what would happen in an emergency. What if there were numerous large people on board, and there was a fire? So, are there any limits to how much the airlines can squeeze their planes' aisles?
an airline couldn't introduce a cabin in which some or all passengers travel in a reclining, rather than sitting, position? Seems to me that it would be more comfortable (except for claustrophobes and those who really need to work during the flight). The enclosed space would inherently reduce some of the risks of passengers being thrown around in turbulence or an emergency landing; safety belts (or cargo restraint webbing? I'm not sure I'm joking) could handle the remaining risk. No, I don't really think it would be commercially viable ... but I'm wondering whether folks who actually Know
So every once in awhile I see an article talking about the air traffic control strikes in Europe like this one: European air traffic controllers to strike. How does this affect me if I am flying to Europe? Do they just close the doors and all airspace becomes uncontrolled airspace? I'm guessing not, but that's what I envision when I hear that! What happens if they go on strike while I'm over the ocean on my way there?
There've been a lot of questions lately about tracking aircraft, and after a conversation with a friend of a friend I started wondering: Could a PLB or EPIRB carried by a passenger or crew member... about electronic devices in flight, and that's not what I'm interested in. I also realize that airliners already carry an ELT. If a paranoid passenger brought one on board, would these devices function at all from inside an airliner cabin? Some feed GPS location data to a 406MHz locator beacon, and those would potentially be less useful (as they'd have to be at hand and probably triggered manually
There are two main types of supplementary oxygen devices in light aircraft: Cannula: Oxygen mask: What are the major differences between these two devices? Is one more suitable for specific siutations than another, or is it just a matter of personal preference?
Primary target: An aircraft not reporting mode-C, the only thing the controller has is the return on the radar. When a controller reports a primary target as traffic to other aircraft, the controller does not have the altitude of the target. Given this, I conclude that ATC radar does not have the altitude (angle-up) to the target, and only provides azimuth. So then without the altitude, how does the radar-system know where to put the target laterally on the screen? Example, a radar picks up a target that is 10 miles from the station. If the target is 0 AGL, the proper position would be 10
