Development and Evaluation of Mission Task Elements for Certification of Aircraft with Non-Conventional Control Interfaces

Abstract

Electrification of aircraft is resulting in configurations that had not been possible. These configurations use fly-by-wire flight controls and introduce novel control concepts that do not map back to traditional mechanical flight controls. The control concepts also do not map to existing Federal Aviation Administration (FAA) certification requirements and therefore need alternate means of compliance. This report addresses that need by considering the use of Cooper-Harper Ratings, ADS-33, and developing a means of compliance for transportation missions. Additionally, a lift + cruise aircraft simulation was developed and implemented in the National Aeronautics and Space Administration (NASA) Langley Research Center\u2019s Cockpit Motion Facility to evaluate the means of compliance developed. The report presents a possible approach and discussion for using the Cooper-Harper rating scale. It also contains discussion about the use of ADS-33. A means of compliance for evaluating 14 CFR Part 23 rules for stability and controllability is presented. The means of compliance was evaluated in the simulation and results are discussed. The researchers did not conclude that use of CHR was helpful for certification
