Aircraft stability detection using fluid motion for flight-control feedback

Abstract

Disclosed is a stability-detecting angle of attack (AoA) system for aircraft, enhancing flight safety by monitoring and managing stability. The system includes an AoA sensor for measuring angle of attack, multiple liquid-level senders with sensors for local fluid levels and kinematics, and processors for compensating fluid motion and temperature. An avionics controller receives data from the senders and AoA sensor, calculating combined tank levels and aircraft stability. It generates flight-control information for feedback mechanisms, including cockpit warnings (audible, haptic, visual) and auto flight process changes. The system aims to prevent loss of control at low speeds by alerting pilots to performance issues and structural risks.
