Method of monitoring and displaying health performance of an aircraft engine

Abstract

A method of monitoring and displaying health performance of an aircraft engine is disclosed. The method comprises the steps of: (a) sensing engine parameters at operable positions of the aircraft engine; (b) recording and generating continuous output signals reflective of the current behavior of the aircraft engine; (c) comparing said output signals with a set of predetermined reference signals to determine if each individual parameter is operating in the safe or danger region; (d) providing an indication of the engine parameter if it is in the danger region; and (e) simultaneously displaying all representative values of the health parameters in a digital and graphical form. The output signals are displayed on a multi-function display and are displayed in a qualitative form. Two different layouts are presented, that is, the bar format and the dial format. Visual effects to give an intuitive display are greatly enhanced through the use of colors and changes in the display format. The final result of the present invention is a display that greatly improves the situation awareness of the pilot in operation of the aircraft.
