Abstract

In an example, method of controlling thrust produced by a plurality of engines on an aircraft for assisting with nose-down recovery of the aircraft is described. The method includes selecting a maximum value of an aircraft parameter, measuring a value of the aircraft parameter while the aircraft is in flight, based on a comparison of the maximum value and the measured value determining that the measured value exceeds the maximum value, and reducing a thrust produced by each of the engines of the plurality of engines to bring the measured value of the aircraft parameter below the maximum value of the aircraft parameter.
