- - According to the Lear Jet's website, the new LearJet 85 has an operational Ceiling of 49,000 ft. This is probably based on maintaining a comfortable cabin pressure. If you ignore that and take along your own oxygen, the structure of the aircraft (taking into account lift and thrust, etc), probably can go much, much higher. I've heard that the record for a Lear Jet is over 85,000 ft. Probably reached by a die-hard test pilot.
The cruising altitude of a normal commercial jet airplane today is around 12,000 m (35,000 ft).
around 40,000 feet. 12,000 meters.
A normal commercial jet can cruise at a speed of mach 0.85 or about 570 miles
Usually, all commercial jet aircraft cruise between 30000 and 40000 feet.
35,000ft is the typical cruising altitude.
The cruising altitude of Boeing 747 is 30,000 feet.
The cruising altitude of a 747 depends on weather conditions, weight of the aircraft, and the amount of traffic on the other flight levels. Its average cruising altitude is around 33,000 feet.
It depends on the aircraft, altitude, headwind, etc. If you we're on a jet cruising at 36,000 ft, you could be going mach 0.6.
Zero, if the jet plane is on the ground, otherwise it depends at what altitude the plane happens to be flying. Cruising altitude for many passenger airliners is around five to seven miles. Military aircraft often fly at much higher altitudes.
Boing 747's, popularly known as Jumbo Jets, typically cruise at around 32,000 to 38,000 feet altitude. This is between about 6 and 7 miles high.
During IFR flight, ATC will dictate cruising altitude.
Cruising altitude is an economical height for an aircraft to fly. It is also a choice made in view of other aircraft routes.
