... 44 m/s. The aircraft will begin to lift soon after the stall speed is reached, hence the estimated take off speed of 50 m/s. For landing we decided that a greater degree of control may be required than take off and therefore the estimated landing speed of 55 m/s was chosen. In deciding these values we are assuming that the aircraft is operating in normal weather conditions and that the aircraft is taking off and landing at sea level. During take off and landing it was assumed that the full movement of the aileron would be required in order to perform these difficult manoeuvres, hence the aileron deflection being the maximum amount. During cruise it was decided that the aircraft would not require the full deflection of the aileron as the aircraft is a passenger airline and will not be performing any high g manoeuvres of the type a military aircraft ...
