摘要

This study presents the development and integration of a Flight Envelope Monitoring System (FEMS) into the Flight Control Panel (FCP) of the LSA-02, a general aviation experimental aircraft. The system is designed to enhance pilot situational awareness and act as a passive safety layer by issuing real-time alerts when flight parameters approach or exceed predefined safety limits, especially in the case of Flight Control Laws (EFCS) failed to provide flight envelope protection. The research involves defining the aircraft’s safe flight envelope, developing a visual alert system using QT and MATLAB Simulink, and integrating it with existing FCP hardware. Hardware-in-the-loop (HIL) and man-in-the-loop (MIL) simulations were conducted, involving two pilots with varying experience levels, to assess response time and situational awareness using the Situational Awareness Rating Technique (SART). Results show that FEMS significantly reduces pilot response time by more than 60% on average and improves awareness during simulated envelope excursions. These findings demonstrate the effectiveness of embedded, non-intrusive safety systems in supporting flight testing and experimental operations where redundancy is limited.
