To ensure stable urban flight of electric vertical take-off and landing(eVTOL) aircraft, securing handling qualities and stability is essential. However, clear handling qualities standards for eVTOL aircraft, which have different characteristics from conventional manned aircraft, have not yet been established. Therefore, this paper identifies handling qualities evaluation criteria suitable for eVTOL aircraft based on the handling qualities standards for manned aircraft and designs a control system that meets the predicted handling qualities criteria through evaluation. simplified vehicle operation(SVO) control laws and stability and control augmentation system(SCAS)-based control laws were applied to the lift-cruise configuration eVTOL aircraft. Using control designer's unified interface(CONDUIT), it was confirmed that the level 1 standard was met, and to validate the system, assigned handling qualities evaluation was performed using handling qualities task elements(HQTE) in an X-Plane based simulation environment, resulting in the design of a control system that ensures handling qualities.
