Definition
The phase of flight that begins with the airplane accelerating along the runway under takeoff power and continues through liftoff, initial climb, and the establishment of a stable climb attitude and airspeed at a safe altitude. It encompasses the transition from ground operation to sustained flight, including rotation, lift-off, and the climbout to a safe maneuvering altitude.
Plain English
The part of the flight where the airplane speeds up on the runway, lifts off the ground, and climbs away from the airport until it reaches a safe height and steady climb.
Context Anchor
Seen in departure training, checklists, and pilot technique discussions for the first part of a flight after starting down the runway.
Derivation
“Takeoff” comes from the everyday phrase “take off,” meaning to leave a surface or depart. In aviation, it means the airplane leaving the runway and becoming airborne. “Climb” means to go upward; in flight, it means gaining altitude after liftoff.
Why Pilots Care
Most accidents occur in this phase; correct speed, attitude, and power management prevent loss of control and ensure obstacle clearance.
Grounding Statement
During takeoff and climb, the airplane changes from rolling on its wheels to flying upward away from the runway.
Intuition Check
Do not think of takeoff and climb as only the instant the wheels leave the ground. In FAA flying use, it includes the runway acceleration, liftoff, and the controlled climb after liftoff.
Example Sentence 1
The instructor demonstrated the takeoff and climb, holding the recommended pitch attitude until the airplane reached its best rate of climb speed.
Example Sentence 2
After liftoff the pilot maintained Vx during the takeoff and climb until obstacles were cleared, then accelerated to Vy.
