SYSTEMS AND METHODS FOR ENERGY MANAGED AUTOFLIGHT GUIDANCE USING POTENTIAL FLIGHT PATH ANGLE

Systems and methods for an energy managed autoflight function that enables maneuvers previously done by the speed-on-elevator modes to be achieved while maintaining the autoflight function in speed-on-throttle mode. An autoflight guidance algorithm and strategy replaces speed-on-elevator modes with an automatic flight path angle (Auto-FPA) mode that can control speed-controlled climbs and descents. The autoflight guidance algorithm and strategy provide (i) autothrust and autoflight coordination during speed-on-throttle modes, (ii) and Auto-FPA control law or mode, (iii) the Auto-FPA control law being configurable for fixed thrust modes, and (iv) a speed protection monitoring scheme.

Low throttle rate command compensation via full authority engine trim

An example method includes: determining a throttle command for a servomotor configured to control a position of a throttle lever, where the position of the throttle lever indicates a commanded thrust for the first engine of the aircraft; determining a trim command for the first engine to equalize the thrust of the first engine with the respective thrust of the second engine; determining that a magnitude of the throttle command is less than a magnitude of a threshold throttle command indicative of a dead zone of the servomotor, where the servomotor is irresponsive to a given throttle command within the dead zone; modifying the trim command based on the throttle command to generate a modified trim command that compensates for irresponsiveness of the servomotor to the throttle command; and changing the thrust generated by the first engine based on the modified trim command.
