30 to 40 thousand feet
An average plane flies between 5 to 10 km above the surface of the earth. Planes cannot fly below or above the altitude. After this altitude there is not much air.
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 Eurofighter Typhoon flies at about 1,320 mph at altitude.
Um..wouldn't it be 500 feet above sea level? That's sorta stupid isn't it?
lift acts upward, and weight acts downward
A commericial airliner flies at around 35,000 feet. (30-40,000)
After take-off a plane climbs to a safe altitude before leveling off.
If the lift generated from the wings is greater than the gravity pulling the plane down, the plain gains altitude and flies
The force of gravity exerted on the plane is essentially the same as the force of gravity at the surface of the Earth, as gravity acts on all objects regardless of their altitude. The force of gravity decreases with altitude, but at a height of 8 km, the difference is not significant enough to affect the force exerted on the plane.
The lift force on a plane is equal to its weight when it is flying at a constant speed and altitude. This balance is necessary for the plane to maintain level flight. If the lift force becomes greater than the weight, the plane will climb; if the lift force becomes less than the weight, the plane will descend.
1330m
They usually fly in the stratosphere. That is from 25,000 feet to 40,000 feet. This may differ from palne to plane. A plane like Cessna flies very close to the ground at about 9000 feet.
