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. In this work we extend the analysis of the minimum flyup altitude taking into account the terrain slope and then repeat all the derivations of equations from this new expression of the minimum flyup altitude. The results of our work could also be used in the development of a warning system for low altitude flight.
