An analysis of aviation accident statistics has revealed that the majority of accidents occur during take-off and landing. The functions of the integrated control system (ICS) and on-board avionics are defined, aimed to considerable reduction of the flight accidents level of aerospace/high speed vehicles during take-off and landing. Algorithms have been developed for the purpose of limiting the pitch and bank angles during take-off and landing of aerospace and high speed flying vehicles. The maximum allowable pitch and bank angles are dependent upon the height above runway. Furthermore, algorithms for engine failure compensation during take-off have been developed. The functionality of these systems has been analysed through simulation and tested in flight simulators. The trajectory safety system's functions are proposed, including motion prediction, detection of conflicts with terrain, traffic and atmospheric factors and generation/indication of safe trajectories to resolve conflicts.
