Aircraft Engine Fan Speed Display Improvements for Enhanced Monitoring and Thrust Setting Ability

摘要

Systems and methods for displaying N1 speed on a flight deck display in a manner that provides increased resolution at the upper end of the operating range. This is accomplished by a variable scale(s) which improves the functionality of the N1 gauge (serving as an indication of thrust) in the desired region. Also, there is visual indication to provide pilots the ability to discern if the current thrust is within a specific tolerance to the desired value within the takeoff region. This additional indication is based on color changes associated with the N1 display structure.

1. A computer-implemented method for displaying aircraft engine information, comprising: acquiring a value of an engine control parameter during operation of an aircraft engine, wherein the engine control parameter has a nonlinear relationship with thrust; displaying a scale on a display unit; and displaying first symbology having a position relative to the scale using a nonlinear scaling function, the first symbology representing the acquired value of the engine control parameter.
