One simple reason: practicability. First of all parachutes are expensive. And having 200 or more parachutes on a fleet of 150+ airplanes would blow airlines' budgets to pieces. Another reason: weight. The weight of all the parachutes would severly limit the capacity of an aircraft. And finally, parachutes are sometimes difficult to operate and would not work with children or people with special needs.
Also, many aircraft accidents happen either immediately after takeoff or just before landing, and there is no time to get all the passengers to put on parachutes (almost all of whom would never have had done so before), get them to the exits and get them out of the airplane, which would also need to be at a sufficient altitude for the parachutes to open safely (before the person wearing the parachute hits the ground). Another consideration is weight and balance. Having all the passengers run to the back of the airplane so they can jump out, when the airplane is already in trouble, may not be the best thing to do (can't jump from the front doors; too many things to hit (i.e., wings, tail, antennas, landing gear, flaps, etc.), and the possibility of ingestion into the engines!) The January 2008 accident involving a British Airways 777 at London-Heathrow is a perfect example of an incident where there was absolutely no time to respond. The flight crew didn't even have time for a 'Mayday' call on the radio, or to tell the passengers and cabin crew to brace for impact. Things can sometimes happen very, very quickly, and in this case the flight crew did an excellent job in getting the airplane on the ground in as few pieces as possible.
Cargo planes do not carry passengers. Some commercial planes make "ghost flights" with no passengers on board.
No, not on any routine commercial flight with passengers.
Yes they are. Military planes are used for fighting against targets with bombs and missiles.Commercial planes are used for transporting passengers from airport to airport- continent to continent. Some commercial planes can be converted into military planes for military use and vice-versa.
Commercial airports have planes with seat numbers to assist boarding and the airspace connecting airports have planes in transit carrying passengers sitting in numbered seats
yes they can
The following precautions must be observed by airline passengers during take off: passengers must be aware of the exits, how to put on the oxygen masks and other in case of emergency precautions, when they can move about and socialise.
There are many different types of planes aside from the commercial airliners that people use daily to get one from part of the world to another. More specialized airplanes include military helicopters, propeller aircrafts, helicopters, and pusher aircrafts.Commercial and navy are your basic groups of planes. Commuter planes carry a small number of passengers and commercial planes vary in passenger accommodation. Manufacturers like Boeing make commercial planes in all sizes like the Boeing 737 and Boeing 747.
I can only use my common sense to guess at an answer to this, but would have thought that the idea of the pilot ejecting himself or herself from a commercial aeroplane, while 400 passengers in the cabin are left to their own devices would be pretty unpopular amongst these very passengers.
One EasyJet Plane (Airbus A319) can carry about 124 passengers. So, 20,161 such planes would be needed for 2.5 million passengers.
About 8-10% of Americans fly on planes daily. This is about 1.73 million flyers each day. Passengers, however, are not just relegated to large commercial flights. In fact, the percentage includes individuals that fly on small commuter planes, helicopters, and even private planes daily.
The 747-800 model planes can carry up to a allowed 605 people. More people would fit but the emergency exits will not allow more people.
Because the passengers can not be interviewed and no one knows who they are.
