Definitions

  • the following disclosure generally relates to display systems for mobile platforms. More particularly, the following disclosure relates to systems and methods for suggesting context-relevant communication frequencies for an aircraft.
  • Pilots are generally required to communicate with a control agency or authority, such as air traffic control (ATC), during all phases of a flight of an aircraft.
  • ATC air traffic control
  • each phase of the flight may require a pilot to communicate with a different control agency.
  • these different control agencies may require communication to be exchanged at different frequencies. Further, these communication needs are shared with Urban Air Mobility (UAM) vehicles.
  • UAM Urban Air Mobility
  • a pilot may need to communicate with an airport ground control at a first frequency while performing the taxi operation, whereas a clearance to get on a runway for take-off may require the pilot to communicate with an airport control tower at a second frequency.
  • a pilot may have to reference a static published chart, either in paper or in an electronic format, based on a visual read of a dynamic current position of the aircraft.
  • the static published chart typically has assignments of frequencies required for regions of the airport environment. By comparing these two elements, the pilot mentally/manually determines a communication frequency to use. This presents a technical problem, in that, a taxi operation is already a dynamic and high work-load operation, so a requirement for a mental determination of communication frequencies, particularly at that phase of flight, may further increase the already high workload and risks introducing pilot errors.
  • An embodiment of a display system for suggesting a communication frequency that is relevant to a context of an aircraft including: a source of an intended flight path; a position determining system configured to determine a location and an orientation for the aircraft; an on-board source of communication frequencies, having stored therein a plurality of communication frequencies; and a controller circuit operationally coupled to the source of the intended flight path, the position determining system, and the source of communication frequencies, the controller circuit configured to: determine a context of the aircraft, as a function of the intended flight path and the location; present, in a predefined area on an avionic display, a list of multiple relevant navigation communication frequencies that are relevant to the context; and tune a communication circuit to a relevant navigation communication frequency of the multiple relevant navigation communication frequencies, responsive to pilot input, or activate a relevant navigation communication frequency of the multiple relevant navigation communication frequencies, responsive to pilot input.
  • the method including: at a controller circuit operationally coupled to a source of an intended flight path and a position determining system, determining a location and orientation of the aircraft; referencing an intended flight path; determining a context of the aircraft, as a function of the intended flight path, a location; using the context to reference an on-board source of communication frequencies, having stored therein a plurality of navigation communication frequencies; and presenting in a predefined area on an avionic display, a relevant navigation communication frequency.
  • Embodiments of the present disclosure may be described herein in terms of functional and/or logical block components and various processing steps. It should be appreciated that such block components may be realized by any number of hardware, software, and/or firmware components configured to perform the specified functions. For example, an embodiment of the present disclosure may employ various integrated circuit components, e.g., memory elements, digital signal processing elements, logic elements, programmable logic arrays, application specific integrated circuits, look-up tables, or the like, which may carry out a variety of functions under the control of one or more microprocessors or other control devices.
  • integrated circuit components e.g., memory elements, digital signal processing elements, logic elements, programmable logic arrays, application specific integrated circuits, look-up tables, or the like, which may carry out a variety of functions under the control of one or more microprocessors or other control devices.
  • integrated circuit components e.g., memory elements, digital signal processing elements, logic elements, programmable logic arrays, application specific integrated circuits, look-up tables, or the like, which
  • pilots are generally required to communicate with a control agency or authority, such as air traffic control (ATC) during all phases of flight.
  • ATC air traffic control
  • each flight phase may require a pilot to communicate with different control agency, and each control agency may require communication to be exchanged at different frequencies.
  • an airport ground area may be divided into multiple regions each having a respective assigned ground control frequency; and each runway at that airport ground area may use a different tower frequency.
  • the taxi route may transit the aircraft through two or more of the multiple regions, requiring that the pilot change ground control frequencies accordingly. Further, when crossing a runway during taxi operations, the pilot may have to switch from ground control frequencies to tower frequencies to obtain a crossing clearance.
  • ATC enroute instructions can be "Contact Phoenix Tower" without a specific frequency for the Phoenix tower; this may be because ATC may not be aware of approach runways for the current approach, nor be aware of a respective approach control frequency associated with the respective approach runways. In these scenarios, the pilot must specifically search and find an approach runway and an approach control frequency associated with the approach runway.
  • a technical solution is disclosed herein in the form of systems and methods for suggesting a communication frequency that is relevant to a context of an aircraft.
  • Proposed embodiments offer a technical solution to these problems with a smart frequency engine that can suggest a communication frequency.
