Flight Guidance Command Generation for fully automatic Flight Missions of an eVTOL Aircraft in Areas difficult to access

Rescue missions of injury trauma patients require quick transport from areas difficult to access to a medical facility. Electric vertical takeoff and landing (eVTOL) vehicles offer fast and cost efficient transport in this scenario. Therefore we developed an automatic takeoff and landing (ATOL) system for eVTOLs. For navigation it either uses sensor data from satellite navigation, or from a local positioning system for robust high precision landing. We integrated the ATOL system with pre-existing modules for waypoint-based path generation and trajectory control into a unified trajectory module. This module generates commands to an inner control loop to fly automatic missions specified by a waypoint list from an operator on ground. The code of the unified trajectory module adheres to a process aiming to fulfill DO178 guidelines. As an application example, we present simulation results for an eVTOL aircraft with a MTOW of 695 kg currently in development by an industry partner.
