Abstract
A process and device are disclosed for detecting the lift-off of an aircraft during the course of take-off. Both during a phase of rolling down the runway and a take-off phase, the quantity A=K.h+&thgr; is calculated. In this equation, &thgr; is the longitudinal attitude of the aircraft, h is the height of the aircraft's tail skid, and K is a constant. After the value of A is calculated for the rolling phase, it is stored. The take-off phase of the aircraft is determined by detecting a particular difference between the stored value of A and a current calculation of A.
