Question

Assuming an aircraft goes over it's ceiling altitude,apart from lack of oxygen,what other problems will arise?

Answer 1

Its engines could "flame-out" do too air thats too thin to sustain fuel burn with.

Hey guys out there, am I right?

Answer 2

the aircraft fuselage (structure) might be compromise. Imagine around 8pounds of pressure acting upon an inch piece of the aircraft against 4 or 5psi outside.

Answer 3

All the previous answers are wrong.

The CEILING given for an airplane is the maximum altitude to which the airplane is capable of climbing under normal conditions.  The airplane cannot "go over" its ceiling.  Under some conditions, a lightly-loaded airplane might exceed its published ceiling for a short time, but great safety factors are built in, so it is not possible for an airplane to climb high enough for fuselage integrity, pressurization, flame-outs, or other disasters mentioned above to occur.

Again, ceiling is a property of the airplane, and cannot be exceeded.

Answer 4

Fuselage problems, cabin pressurization, since today's plane's cabins are not designed to go up so high while being pressurized at a much lower level.

Engine problems.

The engines could surge and suffer a compressor stall, as the air is to thin, and the height is way over the designed limits of the engines. If the engines cut out, power could be lost, and the plane would then start to descend.

Falling Airspeed.

Falling airspeed could bring the aircraft to a stall, and a lack of airspeed could render the plane uncontrollable (if it falls from the sky on it's back or there is not enough air for the control surfaces to be effective).

Usually planes don't go over their ceiling altitude. They are controlled by their design limits, for example, a plane that is meant for 41000ft max may not be able to reach 50000ft, since the airspeed would fall and the wings won't be able to produce much lift to climb.

Answer 5

It isn't the lack of oxygen being a problem, planes cannot go high enough for it's passengers to suffer. It is the pressurisation of the aircraft.  The fueselage wouldn't withstand such pressure.
