The altitude ranges from 30,000 feet to 45000 feet. This is only average altitude. This range is suitable when the plane has levelled.
The cruising altitude of a normal commercial jet airplane today is around 12,000 m (35,000 ft).
It depends on what kind of jet or commercial airplane it is.
A normal commercial jet can cruise at a speed of mach 0.85 or about 570 miles
It's 1/2 of the airplane's top speed ... a different number for every model of aircraft.
Usually, all commercial jet aircraft cruise between 30000 and 40000 feet.
If a commercial passenger jet can travel up to 970 km per hour at an altitude of 30,000 feet, it would take just under 3 hours to travel 2,902 kilometers.
Most commercial jetliners fly routes between 28,000 and 35,000 feet.
No. There were many commercial airplanes before the Boeing 707. The 707 is famous for being the first widely successful jet-engined airliner.
because it has been pressurised in a similar way (outcome) to how a commercial airplane is pressurised for passengers to fly at altitude.
Maximun is 45,000 ft under ATC, Absolute Maximun is 60,000 without special permission from the FAA
The first jet airplane was designed in Germany in the early 1940's.
The airplane was flying at a very high altitude.
