spoilers are used ,ailerons are used for landing.
(DrStrong) This question can be answered in a number of different ways.
You can say that the attitude of the airplane is controlled to be nose-high during landing (i.e., greater wing angle of attack), so as to provide higher lift at lower airspeed.
In terms of thrust, the engine RPM is controlled to give the necessary amount of thrust to achieve the desired speed.
In terms of control surfaces, flaps are adjusted to provide greater lift and also to increase drag. Greater lift means that the aircraft can fly slower while maintaining steady level flight. If the aircraft needs to lose altitude quickly, full flaps can help to keep the aircraft from attaining too much speed during the descent.
In reality, all of these these factors are controlled together to determine the speed and rate of descent of an aircraft on final for landing.
