That depends on a few things. How big is the plane, how many engines does it have, how many blades on each propeller, etc. More blades will let the aircraft keep moving forward and maintain lift at higher altitudes where the pressure is low, but if speed isn't the problem, then the question is if the engine can get enough oxygen to keep the engine running. If the pressure is too low, then the engine will stall and shut down. Restarting the engine again after having fallen to a lower altitude ought to work. As for the average ceiling, I'd say no higher than 40,000 feet if you can get that high, probably 30,000 feet would be the ordinary limit.
A turboprop aircraft, such as a Cessna, cannot fly as fast as a turbofan aircraft, such as a Boeing. Because of this, lift cannot be maintained at high altitudes. As you go higher, you can go faster because there's less air to slow you down. But if you don't go fast enough, then the plane will stall and keep falling until it reaches an altitude at which lift can be maintained at its current speed.
500 miles per hour
The propeller on a turboprop airplane engine spins to move the aircraft through the air. It acts in a way similar to that of the blade in a fan.
The worlds first Turboprop engine was designed in 1928 by a mechanical engineer named Gyorgy Jendrassik. He patented the engine in 1929 and in 1938 built a small scale prototype.
an engine-less aircraft is more likely to glide than fly. It may gain altitude by riding on updrafts though.
turboprop
jet fuel
Twin engine, turboprop, for general aviation.
Piston, turbojet, turbofan, turboprop to name a few.
Helicopters fly somewhat close to the ground. They fly near the troposphere. They fly at a lower altitude than planes.
the types of statore are compressor, gas turbine, turboprop, and jet engine
Calculate the distance in nautical miles (1.15x) and calculate given the KIAS of the turboprop aircraft that you are looking at. Possible KIAS = 250-300 kts.
