Climb (aeronautics)

In aviation, a climb or ascent is the operation of increasing the altitude of an aircraft.

[2]: § 15.8  Excess thrust might fall to zero as a result of the pilot's deliberate action in control of the output of the engines, or as the engines' response to reducing air density.

A gradual climb improves forward visibility over the nose of the aircraft.

Normal climbs are simply standardized climb rates achievable by most aircraft under most conditions that are used as conservative guidelines when developing procedures or structures that are partially a function of such rates.

For example, a normal climb of 20 meters per km (120 feet per nautical mile) might be assumed during the development of a navigational procedure or while defining airspace limits in airport terminal areas.
