The increase in lift and drag enables a slower and steeper approach for landing before deploying the braking systems.Īn additional beneficial effect of extending the flaps is a reduction of the aircraft’s pitch angle, which lowers the nose giving the pilot a better view of the runway. For landing, the flaps can be fully extended and will typically be Pilots need to think ahead, anticipate and make calculated adjustments to allow for wind speed and runway conditions.ĭuring take-off, the flaps are usually partially extended and set between five and 15 degrees, depending on the type of aircraft. A safe landing is not dependent on the flaps alone. When we trim an aircraft, we are adjusting one or more of the movable control surfaces so that the pilot doesn’t need to hold them with physical strength and can focus elsewhere. Better said, we can replace the word trim with adjust and get a similar meaning. The flaps work in conjunction with the plane’s altitude, power and pitch. What is aircraft trim Aircraft trim is an adjustment to the control surfaces. How the flaps are set during deployment determines whether they provide increased lift for take-off or an increase in drag for landing. Wing flaps alter the shape of the aircraft’s wing and divert the air over and under the wing as required.
