Abstract
A system and method for mapping an aircraft position on segments that lie between waypoints on a non-linear map by converting real world geographic coordinates of an aircraft to image X, Y coordinates using an image X, Y length or scale of a respective segment as a basis for the conversion. The aircraft position may be mapped in real time and presented to a user via an aircraft device.
Claims13
A system for mapping a position on a navigational chart, comprising:
- one or more storage machines holding instructions executable by one or more logic machines to:
- receive a navigational chart;
- receive geographic coordinates of a vehicle as vehicle geographic coordinates;
- identify georeferenceable points on the navigational chart;
- receive geographic coordinates of the georeferenceable points as point geographic coordinates;
- map a position of the vehicle on the navigational chart according to the point geographic coordinates and the vehicle geographic coordinates;
- identify a segment between two of the georeferenceable points;
- map the position of the vehicle on the navigational chart according to the segment, and
- wherein a length ratio between two of the segments is not equal to a length ratio between corresponding real physical geographic distances.

A computing device for mapping a position on a navigational chart, comprising:
- a logic machine;
- and
- a storage machine holding instructions executable by the logic machine to:
- receive, from an aviation authority, a flight procedure chart for a vehicle;
- receive, from a GPS locator of the vehicle, geographic coordinates of the vehicle as vehicle geographic coordinates;
- identify a plurality of georeferenceable points on the flight procedure chart;
- receive geographic coordinates of the plurality of georeferenceable points as point geographic coordinates;
- identify a first segment between a first pair of the plurality of georeferenceable points, the first segment being a nearest segment among a plurality of segments nearest the vehicle;
- map a position of the vehicle on the navigational chart according to the point geographic coordinates, the vehicle geographic coordinates, and a first geographic scale of the first segment;
- and
- display, on a display device, the navigational chart including the position of the vehicle;
- wherein the instructions are further executable to update the navigational chart and the position of the vehicle in real-time according to the first geographical image scale;
- wherein the instructions are further executable to:
- identify a different segment of the plurality of segments between a different pair of the plurality of georeferenceable points, the different segment identified as being nearest the vehicle;
- in response to identifying the different segment as being nearest the vehicle, map the position of the vehicle on the navigational chart according to a different geographical image scale of the different segment;
- and
- wherein differing geographical image scales means a length ratio between two of the segments is not equal to a length ratio between corresponding real physical geographic distances.

- and
- a storage machine holding instructions executable by the logic machine to:

- identify a first segment between a first pair of the plurality of georeferenceable points, the first segment being a nearest segment among a plurality of segments nearest the vehicle;
- map a position of the vehicle on the navigational chart according to the point geographic coordinates, the vehicle geographic coordinates, and a first geographic scale of the first segment;
- and
- display, on a display device, the navigational chart including the position of the vehicle as a moving icon having an icon movement speed across the displayed navigational chart;
- and
- wherein the navigational chart is non-linear such that, while the vehicle has a constant real-world physical speed with respect to real-world positions represented by at least two segments of the segment, the icon's movement speed with respect to a displayed first segment of the two segments is different from the icon's movement speed with respect a displayed second segment of the two segments, while the vehicle has a constant real-world physical speed.
