What increases lift and drag during takeoff and landing?
What increases lift and drag during takeoff and landing? Flaps change a wing's curvature, increasing lift. Airplanes use flaps to maintain lift at lower speeds, particularly during takeoff and landing. This allows an airplane to make a slower landing approach and a shorter landing. Flaps also increase drag, which helps slow the airplane and allows a steeper landing approach.
What are the three 3 factors that affect aircraft performance?
Pressure, temperature, and humidity have a great influence on aircraft performance because of their effect upon density. There is no rule-of-thumb or chart used to compute the effects of humidity on density altitude, but it must be taken into consideration.
