# How does an aircraft descend?

When the force of the lift exactly balances the weight of the aircraft, the plane will fly level; if the lift exceeds the weight, it will climb; and if weight exceeds lift, it will descend. So to make an aircraft climb the pilot increases the engine power; to make it descend, engine power is reduced.

.

Likewise, what angle do planes descend?

A: The normal descent profile is approximately 3 degrees. This can vary, but during the final stages of landing, 3 degrees is usually the target. Wind can vary the groundspeed and descent rate, but the descent angle remains the same.

Furthermore, how do pilots know when to descend? On a normal instrument approach, one radio beam, called the glide slope, gives pilots the proper descent path, generally 3 to 4 degrees downward. The other, called the localizer, provides the exact course to the runway centerline.

One may also ask, how quickly do planes descend?

Many aircraft had a cruising speed between 100–120 miles per hour (160–190 km/h; 87–104 kn). Three miles would be traveled in about 1.5–1.8 minutes, resulting in a rate of descent of about 550–660 feet per minute (2.8 to 3.4 meters per second).

Why do planes descend slowly?

More power = more speed = more lift One very simple way to descend therefore is to reduce power. This will slow the aircraft down, so the wings produce less lift, and the plane slowly falls.
