Calculations were carried out on a Boeing 707 aircraft in order to assess the effects on longitudinal stability of steep approach landings. The investigations point out that the present passenger aircraft can perform steeper than usual landings. The sinking velocity will increase as the path velocity remains unchanged. In order to avoid too much throttling of the engines, the air brakes should be lowered. The dynamic longitudinal stability is only slightly disturbed. The angle of attack oscillation will be slightly undampened, the phugoid dampened. A glide path of 3 deg is recommended.
