Climb

From Wikipedia, the free encyclopedia

The climb is the part of a flight of an aircraft, after take off, consisting of getting the aircraft to the desired flight level altitude. More generally, the term 'climb' means increasing the altitude.

A pilot generally induces a plane to climb by setting the appropriate power level and using elevators to adjust the pitch of the plane for the appropriate speed. This technique is far more effective than trying to achieve a particular climb rate directly.

During long climbs the angle of climb is often reduced. Whilst slowing the speed of ascent, more forward progress is made toward the destination, often saving time when taken over the entire journey. An added benefit is more forward visibility over the nose of the aircraft and an increased flow of cooling air to the engines. If the pilot tries to climb too fast, a stall may occur.

All aircraft, but especially gliders can also ascend by using rising air, (see article on gliding). For lighter aircraft this method can achieve faster rates of climb than by using engine power.

Opposite to the climb is descent.
