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.

Abstract: A fuel-level detection system is configured to determine a fuel level in a fuel system. A comparative fuel probe is associated with the fuel system and includes a capacitive probe assembly configured to provide a comparative capacitive reading, and a float assembly configured to provide a comparative float reading. A comparator is configured to receive the comparative capacitive reading and to receive the comparative float reading, and to determine a corrective factor based at least in part on the comparative capacitive reading and the comparative float reading. A set of capacitive probes is associated with the fuel system. The fuel level in the fuel system is determined by comparing each local capacitive reading from each capacitive probe in the set of capacitive probes with the corrective factor.
