Table 103 Flight Profile Phases
Phase Description
Prelaunch The phase of flight in which an aircraft goes through a series of checkups (hardware and
software) on the ground before takeoff. The aircraft is a static condition,
Takeoff The phase of flight in which an aircraft goes through a transition from moving along the
ground (taxiing) to flying in the air, usually along a runway. The aircraft is under
nd horizontal acceleration and may suffer from vibrations coming from an engine and grou
contact forces transmitted from its landing gear..
Climb The phase of a flight, after takeoff, consisting of getting the aircraft to the desired flight
level altitude. More generally, the term 'climb' means increasing the altitude. The aircraft is
under vertical acceleration until it reaches the steady‐state climb rate.
Straight and level
flight The phase of flight in which an aircraft reaches its nominal flight altitude and maintains its
speed and altitude. The aircraft is under equilibrium.
