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.
The plane reached its cruising altitude of 30,000 feet.
About Half an hour.
There is no certain cruising altitude for a commercial airline. it depends on where they are flying and how long they fly. most airlines fly above 10,000 ft. the max altitude is around 41,000 ft.
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.
Before the Concorde's retirement it was the fastest passenger plane, cruising at Mach 2.02 (~1320mph). Now the fastest planes are the 787 and A380, optimized for Mach 0.85 (~567mph).
Cruising altitude is an economical height for an aircraft to fly. It is also a choice made in view of other aircraft routes.
During IFR flight, ATC will dictate cruising altitude.
We will fly a VFR flight heading 245 - what is a legal cruising altitude?
