METHOD AND SYSTEM FOR PREVENTING UN-COMMANDED POWER SURGE OF AIRCRAFT ENGINE

摘要

A method of preventing un-commanded power surging of an aircraft engine includes two steps of detecting whether the Weight-On-Wheels signal is on and detecting whether the Low-Power-Lever-Angle-Discrete signal is on, which indicate whether the aircraft is on the ground and whether the throttle lever is positioned for a low power range. If both results are positive, a further step is performed for comparing a measured engine power or thrust level with a predetermined threshold and a final step reduces the fuel supply or shuts down the engine, if the measured engine power level is greater than the predetermined threshold.
