    Abstract: 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.

    Abstract: An aircraft flight control system and method are provided. The system provides a control module that receives inertial data, sensor data, and a target airspeed. The control module processes the received data with aircraft thrust and drag models to evaluate the aircraft energy state. Based on the aircraft energy state, the control module determines (i) a maximum predicted potential flight path “max PPFP”, defined by a maximum thrust at the target airspeed, and (ii) an idle predicted potential flight path, “idle PPFP,” defined by an idle thrust at the target airspeed. The control module generates display commands for a display system to display (i) the flight path angle, (ii) the max PPFP and (iii) the idle PPFP. In addition, the control module generates and displays a predicted flight path speed indicator (PFPS) when the FPA is above the max PPFP or below the idle PPFP.

    Abstract: Technologically improved vehicle control systems and methods are described. The provided vehicle control systems and methods embody an inner loop auto-throttle control for causing delta-throttle changes, i.e., servo changes, to achieve desired acceleration targets. The system generates an error on a potential flight path angle using a received thrust acceleration command. The error on the potential flight path angle is converted into an equivalent acceleration. A throttle rate command TLA_ratecmd is generated by converting the equivalent acceleration into the throttle rate command TLA_ratecmd.

    Abstract: Techniques for integrating a travel control system and attitude and heading (AHR) system in a vehicle are disclosed. The integrated system includes interface circuitry that enables data communication between constituent travel control system and AHR system of the integrated system, and can further communicate data between the travel control system and/or the AHR system and other system(s) or device(s) in or on the vehicle. In some embodiments, the travel control system includes processing circuitry that is fault tolerant. Alternatively, or additionally, the AHR system may include processing circuitry that has a processing power greater than the travel control system processing circuitry.
