Abstract
A system and method are provided for displaying visual flight reference points and their associated flight data. This is achieved by coupling a processor to a display system and configured the processor to generate symbology graphically representative of the VRPs and their associated flight data. The display system then renders the VRP symbology and the flight data symbology proximate to the VRP symbology. In addition, the processor is configured to alter the symbology of the VRPs depending on the estimates elapsed time for each of the VRPs to become visible to the aircraft.
Claims9
A method, execute by a processor, for displaying visual reference point (VRP) data on an aircraft display, the method comprising:
- retrieving data associated with a VRP from a database;
- processing the data associated with the VRP to generate:
- (i) a bearing of the aircraft relative to the VRP,
- (ii) a distance from the aircraft to the VRP, and
- (iii) an estimated time of arrival of the aircraft to the VRP;
- rendering a symbol graphically representative of the VRP on the display and;
- displaying on the display, proximate to the symbol for the VRP,
- (i) the bearing of the aircraft relative to the VRP,
- (ii) the distance from the aircraft to the VRP, and
- (iii) the estimated time of arrival of the aircraft to the VRP, and
- creating a region on the aircraft display that is bounded by the symbol for the aircraft, a VRP, a point where extending a perpendicular line from the VRP to the flight path intersects the flight path, and displaying the region in a visually distinguishable manner.
A system for displaying data associated with a plurality of visual reference points (VRPs), comprising:
- a database of data associated with VRPs;
- a user interface for obtaining a tagged VRP;
- a display system;
- and
- a processor coupled to the database, the user interface, and the display system, the processor configured, in response to data associated with VRPs, to
- (1) differentiate between VRPs that are visible at night-time and the VRPs of the plurality of VRPs that are visible during the day-time;
- (2) represent, on the display system, VRPs visible during the day-time with a first symbol;
- and
- (3) represent, on the display system, VRPs visible at night-time with a second symbol;
- the processor further configured, in response to obtaining a tagged VRP, to display system to render, proximate to the tagged VRP symbol,
- (i) a bearing of the aircraft relative to the VRP,
- (ii) a distance from the aircraft to the VRP, and
- (iii) an estimated time of arrival of the aircraft to the VRP,
- wherein, responsive to the tagged VRP, the processor further:
- creates a region on the aircraft display that is bounded by the symbol for the aircraft, the tagged VRP, a point where extending a perpendicular line from the tagged VRP to the flight path intersects the flight path, and
- commands the display system to render the region in a visually distinguishable manner.
