Abstract:
New methods are currently being investigated to perform certification of future electric Vertical Take-Off and Landing (VTOL) aircraft. Due to the expected mission requirements, classical certification methods do not lend themselves to this type of vehicle. One aspect being investigated is a new approach to evaluate Handling Qualities (HQs) as means of compliance demonstration. The EUROCAE Working Group 112 has proposed new Flight Test Manoeuvres (FTM) that could be used for this purpose. These FTMs are scaled based on vehicle geometry. This paper presents first results obtained from a flight campaign to test a set of the proposed FTMs. The flight tests were performed with a coaxial ultralight helicopter and conducted at airport Obermehler (EDCO) in Germany. One pilot flew seven proposed FTMs. Pilot feedback and analysis of results are used to propose modifications to the FTMs.
