DETECTION OF UNCOMMANDED AND UNCONTROLLABLE HIGH THRUST EVENTS

摘要

Herein provided are methods and systems for detecting an uncommanded oruncontrollable high thrust (UHT) event in an aircraft, comprising arming a UHTfunction,comparing an engine fan speed to a reference target and detecting a firstconditionwhen a first threshold is exceeded, comparing a rate of change of a highpressure rotorspeed to a reference deceleration schedule and detecting a second conditionwhen asecond threshold is exceeded, detecting a UHT event based on excess thrustwhen thefirst condition and the second condition are detected, and accommodating theUHTevent.
