WebStated technically, it is the altitude where the maximum sustained (with no decreasing airspeed) rate of climb is zero. Compared to service ceiling, the absolute ceiling of commercial aircraft is much higher than for standard operational purposes. In the Concorde 's case, it was tested to be 68,000 ft (21 km; 12.9 mi). WebAll propeller based aircraft have much lower ceilings and they vary widely with design of the craft. The Turboprop aircraft with the highest altitude ceiling is the Lockheed P-3 ORION, which has a maximum cruise altitude of 55,000 ft. There is a trade off point because as the air gets less dense the plane can travel faster.
