The SAGITTA Demonstrator is a novel UAV with a digital flight control system being developed by the Institute of Flight System Dynamics of the Technical University of Munich. This paper presents the implementation of an automatic take-off algorithm as a system automation module of the auto flight system. Based on a phase-breakdown of take-off, the implementation features a state machine that covers the procedure of the maneuver and the transition conditions from one phase to another. Through this state machine, the automatic take-off algorithm enables controller modules of the auto flight system and provides corresponding commands for the conduct of take-off. The design of the automatic take-off algorithm focuses on maximizing safety and robustness against uncertainties and disturbances. Presented simulation results prove the concept of the algorithm as well as its robustness to simulated reality effects.     «
