In forward flight a helicopter's flight controls behave more like that in a fixed-wing aircraft. Displacing the cyclic forward will cause the nose to pitch down, with a resultant increase in airspeed and loss of altitude. Aft cyclic will cause the nose to pitch up, slowing the helicopter and causing it to climb. Increasing collective (power) while maintaining a constant airspeed will induce a climb while decreasing collective will cause a descent. Coordinating these two inputs, down collective plus aft cyclic or up collective plus forward cyclic, will result in airspeed changes while maintaining a constant altitude. The pedals serve the same function in both a helicopter and an airplane, to maintain balanced flight.

A helicopter is an aircraft that can take off and land vertically. Also called a "rotary aircraft," it can hover and rotate in the air and can move sideways and backwards while aloft. It can change direction very quickly and can stop moving completely and begin hovering.

Rotorcraft brownouts are intense, blinding dust clouds that result from helicopter rotor downwash, which is the forcing of air downward during the creation of lift from dry, dusty terrain. As a result, pilots cannot see nearby objects that provide the outside visual references necessary to control the aircraft near the ground during landing and take-off operations.
