A system for aiding piloting of an airplane during a final approach includes current roll angle sensors that measures a current roll angle of the airplane, and a maximum roll angle calculation device that calculates a limit roll angle corresponding to a maximum roll angle at which an end point of the airplane will not strike the ground. The system also includes a display for automatically presenting on a single screen a first characteristic sign illustrating the current roll angle and a second characteristic sign illustrating the limit roll angle. If a potential ground collision is presented by too high of a current roll angle, an alarm may be emitted or automatic control of the airplane may occur to correct the roll angle.
