A hybrid emergency power unit for an aircraft comprises a controller, a generator-motor coupled to the controller, a hydraulic pump coupled to the generator-motor, a battery pack coupled to the controller, and a turbine coupled to the generator-motor. During a bleed air mode, the turbine and the generator-motor supply electricity to the controller, which is configured to rectify an output of the generator-motor for consumption by one or more electrical systems on the aircraft. During an augment mode, when bleed air provides insufficient power, the controller is configured to draw at least some power from the battery pack and convert the output of the generator-motor for consumption by the one or more electrical systems. During an emergency mode, the controller is configured to draw electricity from the battery pack and provide power to drive the generator-motor, which in turn drives the hydraulic pump and provides electrical power to aircraft systems.

Methods and systems are provided for assisting vehicle operation for collision avoidance. One method involves determining a horizontal adjustment for the vehicle based at least in part on an output from a collision avoidance system and displaying, on a display device, a graphical indication of the horizontal adjustment at a position on the display device with respect to a reference position of a second graphical indication of a current orientation of the vehicle resulting in a distance between the position of the graphical indication and the reference position of the second graphical indication corresponding to the horizontal adjustment. The distance dynamically updates in response to changes to the orientation of the vehicle.

An avionics system in an aircraft for providing flight data from an onboard flight management computer (FMC) to requesting applications is disclosed. The system includes a flight management system (FMS) service layer executing on the FMC on a thread separate from a thread that executes FMS core functions. The FMS service layer provides a FMC networked node server for responding to queries from a plurality of external applications for data generated from the FMS core functions without interrupting the FMS core functions. The FMC networked node server is configured to: receive a request from a client application using a server specified API for data elements from a specified input flight plan; retrieve the specified input flight plan from the FMS core functions; extract the requested data elements; and output the requested data elements to the client application without affecting the active thread that executes FMS core functions.
