    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: Methods and systems are provided for autonomous vehicle operation for collision avoidance. One method involves identifying an autonomous operating mode and one or more settings associated with the autonomous operating mode prior to entering an autonomous collision avoidance mode in response to an output from a collision avoidance system, and after entering the autonomous collision avoidance mode, automatically restoring autonomous operation upon deactivation of the autonomous collision avoidance mode. For example, the autonomous operating mode may be automatically reinitiated based on the current vehicle status using the one or more settings in response to deactivation of the autonomous collision avoidance mode when it is determined that the autonomous operating mode is viable based on a relationship between a current vehicle status and the one or more settings associated with the autonomous operating mode.

    Abstract: Disclosed are methods, systems, and non-transitory computer-readable medium for controlling an automatic descent of a vehicle. For instance, the method may include: determining whether a descent trigger condition is present; and in response to determining the descent trigger condition is present, performing an automatic descent process. The automatic descent process may include: obtaining clearance data from an on-board system of the vehicle; generating a descent plan based on the clearance data, the descent plan including a supersonic-to-subsonic transition and/or a supersonic-descent to a target altitude; and generating actuator instructions to a control the vehicle to descend to the target altitude based on the descent plan.

    Abstract: Disclosed are methods, systems, and non-transitory computer-readable medium for supersonic flight entry/exit management. For instance, the method may include determining whether a transition between supersonic and subsonic flight is approaching; and in response to determining the transition between subsonic and supersonic flight is approaching, performing a supersonic flight entry/exit process. The supersonic flight entry/exit process may include: obtaining center of gravity (CG) information for the vehicle, drag information for the vehicle, and a planned trajectory of the vehicle (trajectory data); performing an analysis of the trajectory data to determine whether the planned trajectory is safe and consistent; based on a result of the analysis, adjusting the planned trajectory or confirming the planned trajectory of the vehicle; and based on the adjusted planned trajectory or the confirmed planned trajectory of the vehicle, generating actuator instructions to execute the adjusted planned trajectory or the confirmed planned trajectory.
