摘要： In an embodiment, a method for aircraft weight estimation is provided that includes determining a weight signal based on a dynamic pressure signal, a calibrated angle of attack signal, a lift coefficient signal, a load factor signal, and a wing surface area. In another embodiment, a method to estimate aircraft weight is provided that includes determining a weight based on historical flight data relating horizontal control surface position to dynamic pressure. In another embodiment, a system for continuously estimating aircraft weight during flight is provided that includes a pitot-static subsystem, an angle of attack indicator, an accelerometer, a controller configured to provide a weight signal, and a signal filter for filtering the weight signal to determine a stable aircraft weight.

摘要： Systems and methods are described for automatically counteracting undesirable aircraft movement caused by malfunctioning fly-by-wire aircraft control surfaces, hardover events, control surface disconnection, and other control surface failure events. The systems and methods include control law algorithms for reacting to such events to counteract the undesired aircraft movement. An expected roll rate is generated based on control input and compared to the actual roll rate of the aircraft.
