What happens if a plane exceeds its service ceiling?

The static ceiling is simply the point above which the aircraft won't be able to produce enough thrust and lift to sustain that altitude. You'll start losing velocity, and as you do so, also start losing altitude. Nothing fails outright. You just don't have enough energy to climb or even stay level.

At absolute ceiling, the aircraft can no longer accelerate, since any acceleration will lead to higher airspeed and therefore excess lift. Stated technically, it is the altitude where the maximum sustained (with no decreasing airspeed) rate of climb is zero.

All aircraft have a specified 'service ceiling' that defines the maximum height at which it should be operated. For most modern commercial jets today, this is around 41,000 feet.

A service ceiling is not really an absolute limit on the altitude that a particular design can achieve, but one at which the aircraft begins to run out of climb capability.

And that at cabin altitudes above 14,000 feet pilots must use oxygen at all times. And that above 15,000 feet each occupant of the aircraft must be provided supplemental oxygen. All of this is spelled out in Federal Aviation Regulations Part 91.211.

CEILING- The heights above the earth's surface of the lowest layer of clouds or obscuring phenomena that is reported as “broken,” “overcast,” or “obscuration,” and not classified as “thin” or “partial.”

The sweet spot for modern airliners is between 35,000 and 42,000 feet, where the plane's engines are most efficient. The way the wings are designed is also unsuitable for thin-air flight as they would not be able to create enough lift. Planes cannot just keep going up and up - at some point, it will stall.

During a belly landing, there is normally extensive damage to the airplane. Belly landings carry the risk that the aircraft may flip over, disintegrate, or catch fire if it lands too fast or too hard.

So the first commercial passenger airline in the series was assigned the number 707 (pronounced Seven Oh Seven). The Boeing 707 is credited with launching the beginning the “Jet Age.” It was decided that all model numbers that either began or ended in a “7” would be reserved for commercial jets.

Boeing and the magic number seven Because Boeing's marketing department intervened, and just as 007 sounds better than plain old 7, 707 sounds better than 700.

The Next-Generation 737 airplanes are capable of cruising to a maximum altitude of 41,000 feet, compared to 39,000 feet for the competition. In addition, advanced-technology Blended Winglets are offered as a production option on the 737-800.
