  • Publication number: 20220121224
    Abstract: A system and method for generating, supplying, and implementing an optimized descent approach profile for an aircraft includes transmitting a current flight plan from an onboard flight management system (FMS) to an off-board computing device. The optimized descent approach profile for the aircraft is computed, in the off-board computing device,. One or more new waypoints or points of interest that are not on the current descent approach profile, but which comprise the optimized descent approach profile, are identified in the off-board computing device. The new waypoints or points of interest are transmitted from the off-board system to the onboard FMS. The current descent approach profile is updated, in the FMS, to include the new waypoints or points of interest, thereby generating an updated flight plan. The updated flight plan is implementing in the onboard FMS.

  • Patent number: 11270593
    Abstract: Methods and systems are provided for optimization of an aircraft flight trajectory with shortcuts. The method comprises retrieving an active flight plan stored in a flight management system (FMS) and identifying a potential shortcut with a shortcut advisor tool. The FMS monitors the location of the aircraft with respect to an identified start point of the potential shortcut. Prior to the aircraft's arrival at the identified start point, current key performance indicators (KPI) of the shortcut are evaluated with the shortcut advisor tool. The aircrew is alerted to the potential shortcut along with a preview of the performance of the aircraft upon accepting the potential shortcut. The aircrew may accept the addition of the potential shortcut to the flight plan and request approval of the shortcut by air traffic control (ATC). The active flight plan is updated with the shortcut upon approval from the ATC.

  • Patent number: 11257388
    Abstract: An obstruction detection and warning system includes a plurality of edge light emitters, and a processing system. The edge light emitters are mounted on a structure that has a width and a height. Each edge light emitter is operable to emit a light beam at an angular rate, and that is encoded with data that indicates its position and its height. The processing system receives the light beam emitted from each edge light emitter and decodes the encoded data from the received light beam to determine the width and height of the structure, and to determine a distance from an aircraft to the structure. The processor also compares an active trajectory and current altitude of the aircraft to the width and height of the structure and the distance to the structure and, based on the comparison, generates and supplies situational cues to an operator of the aircraft.

  • Patent number: 11257379
    Abstract: An embodiment of a communication management unit (CMU) includes emulator and data-mining circuits. The emulator circuit is configured to generate a data request having a same format as a data request from a vehicle communications center, to send the data request to a subsystem disposed on a vehicle, and to receive data sent by the subsystem in response to the data request. The data-mining circuit is configured to provide at least some of the received data to a determining circuit configured to determine information in response to the provided data. For example, such a CMU can request flight-plan data from a flight management subsystem (FMS) by sending, to the FMS, an emulated data-request message having the same format as a data-request message from a ground-based aircraft operations center. That is, the CMU can “fool” the FMS into “thinking” that the data-request message originated from the ground-based aircraft operations center.

  • Publication number: 20210383703
    Abstract: Methods and systems are provided for guiding or otherwise assisting operation of an aircraft en route to an airport. One method involves identifying a reference point in advance of a runway, dynamically determining a gliding vertical trajectory for the aircraft en route to the reference point based at least in part on a current altitude of the aircraft at a current aircraft location and gliding characteristics of the aircraft, and providing a graphical indication of a difference between a predicted altitude of the aircraft at a location corresponding to the reference point resulting from the gliding vertical trajectory and an altitude criterion associated with the reference point. The graphical indication of the difference dynamically updates as the aircraft travels.
