Effects During Takeoff and Landing During the critical phases of takeoff and landing, the pilot's management of the angle of attack becomes paramount, and the fixed angle of incidence provides the necessary background for these maneuvers. The predetermined incidence ensures that once the aircraft is light enough, it naturally wants to climb.

This configuration causes the wing to generate more lift than the tailplane, which would naturally cause the nose to pitch up. The Critical Distinction from Angle of Attack Confusing the angle of incidence with the angle of attack is a common error, yet understanding the difference is vital for comprehending how an airplane generates lift.
Defining the Aircraft's Geometric Reference The longitudinal axis of an aircraft is an imaginary line that runs from the nose to the tail, essentially bisecting the fuselage. A design known as "positive incidence" means the wing is mounted at a slight upward angle relative to the fuselage.

A high angle of attack means the wing is presented steeply to the airflow, which is necessary for generating high lift during takeoff and landing but can lead to a stall if pushed too far. For a typical general aviation or commercial aircraft, the incidence is set so that the wing operates at its most efficient angle—often near the lift coefficient that produces the highest lift-to-drag ratio—during normal cruise flight.
