The main result of our paper is a proposal of a ground collision avoidance system (GCAS) for fighter aircrafts that takes into account not only the limits of the aircraft but also the physiological limits of the pilot to avoid simultaneously a crash and the loss of consciousness of the pilot (G-LOC) during the recovery manoeuvre (flyup). This Anti-G-LOC GCAS is based on a detailed mathematical analysis of the flyup, a detailed model of the flyup duration and a detailed mathematical model of the pilot +Gz tolerance. We also solve the G-LOC problem. The problem that we solved is to maintain the risk of G-LOC in a given flyup under a certain level assuming constant the measured +Gz pilot tolerance. To our knowledge this is the first proposal to solve simultaneously the problems of G-LOC and controlled flight into the ground. Based on a model of pilot +Gz tolerance level we designed the Anti-G-LOC Ground Collision Avoidance System (GCAS) and the Time to G-LOC Meter which helps the pilot to avoid its own G-LOC.
