The model-based development of emergency descent trajectories is presented using the example of a helicopter as a function of flight limitation parameters. The trajectory ensures a fast coordinated and controlled emergency descent in the smallest possible space and from any flight condition. Although the model is based on a helicopter the trajectory can also be transferred to fixed-wing aircraft. The unmanned helicopter is on an aerial photography mission with constant trajectory speed and flight altitude. It should be possible to initiate the emergency descent at any time without exceeding the limiting parameters (e.g. roll time constant, build-up of vertical speed). To be able to perform a safe emergency descent in defined emergency descent areas, the space requirement must be determined in advance by e.g., a validated flight simulation. The seamless connection of the emergency descent in every attitude of the aerial photography flight, as well as the calculation of the trajectory, are the focus of the paper. The results are verified using desktop and real-time simulations with Pilot-on-the-Loop.
