## Abstract

The different advantageous embodiments provide a method, computer program product, and apparatus for presenting a position of a vehicle on a chart. In one advantageous embodiment, a method for presenting a vehicle on a chart is presented. A current position of the vehicle is identified. The method then determines whether the current position of the vehicle is on a path between two points in a plurality of points. A first indicator at a first location on the chart indicating a position of the vehicle on the path relative to the two points is presented responsive to a determination that the current position is on the path. A second indicator on a second location on the chart is presented responsive to an absence of a determination that the current position is on the path, wherein the second indicator points to a closest point in the plurality of points.

## Claims

### Claim 1

A method for presenting a vehicle on a chart, the method comprising:
identifying, using a processor, a current position of the vehicle;
determining, using the processor, whether the current position of the vehicle is on a path between two points in a plurality of points;
responsive to a determination that the current position is on the path, presenting, using the processor, a first indicator at a first location on the chart indicating a position of the vehicle on the path relative to the two points; and
responsive to an absence of a determination that the current position is on the path, presenting, using the processor, a second indicator on a second location on the chart, wherein the second indicator indicates the position of the vehicle relative to the second location, wherein a scale varies throughout the chart.

### Claim 2 (depends on 1)

The method of claim 1, wherein the second location is closer to the current position than the first location.

### Claim 3 (depends on 1)

The method of claim 1, wherein the path between the two points comprises a line and a width on each side of the line.

### Claim 4 (depends on 3)

The method of claim 3 further comprising:
receiving a user input for the width.

### Claim 5 (depends on 3)

The method of claim 3, wherein the step of determining, using the processor, whether the current position of the vehicle is on the path further comprises:
determining, using the processor, whether a first distance between the current position of the vehicle and both of the two points is less than a length of the path;
responsive, using the processor, to a determination that the distance is less than the length of the path, determining whether the current position is within the width of the path;
responsive to a determination that the current position is within the width of the path, determining, using the processor, that the current position of the vehicle is on the path; and
responsive to an absence of a determination that the distance is less than the length of the path, determining, using the processor, that the current position of the vehicle is off the path.

### Claim 6 (depends on 1)

The method of claim 1, wherein the step of identifying, using the processor, the current position of the vehicle is performed using a global positioning system.

### Claim 7 (depends on 1)

The method of claim 1, wherein the step of presenting, using the processor, the second indicator on the second location on the chart further comprises:
identifying, using the processor, a distance and a direction from the current position to the second location, wherein the second indicator comprises an arrow identifying the direction and the distance from the current position to the second location.

### Claim 8 (depends on 1)

The method of claim 1, wherein the second location on the chart is closer than the first location when the current position is within a radius of the second location.

### Claim 9 (depends on 1)

The method of claim 1 further comprising:
receiving, using the processor, a user input comprising a number of points in the plurality of points, wherein the second location is the number of points.

### Claim 10 (depends on 1)

The method of claim 1, wherein the path is a first path, and wherein the first path is presented on the chart on a different scale than a second path on the chart.

### Claim 11 (depends on 1)

The method of claim 1, wherein the chart is selected from a standard instrument departure chart, a departure procedure chart, and a standard arrival chart.

### Claim 12 (depends on 1)

The method of claim 1, wherein the vehicle is selected from an aircraft, an automobile, a surface ship, a submarine, and a spacecraft.

### Claim 13

An apparatus comprising:
a display device; and
a processor unit connected to the display and configured to identify a current position of a vehicle on a chart wherein a scale varies throughout the chart, determine whether the current position of the vehicle is on a path between two points in a plurality of points, present, on the display, a first indicator at a first location on the chart indicating a position of the vehicle on the path relative to the two points responsive to a determination that the current position is on the path, and present on the display device a second indicator on a second location on the chart responsive to an absence of a determination that the current position is on the path, wherein the second indicator indicates the position of the vehicle relative to the second location.

### Claim 14 (depends on 13)

The apparatus of claim 13, wherein the processor unit is configured to present on the display device the second indicator on the second location on the chart further comprises:
the processor unit being configured to identify a distance and a direction from the current position to the second location, wherein the second indicator comprises an arrow identifying the direction and the distance from the current position to the second location.

### Claim 15 (depends on 13)

The apparatus of claim 13 further comprising:
the vehicle, wherein the display and the processor unit are located inside the vehicle.

### Claim 16

A non-transient computer program product comprising:
a computer readable storage medium;
program code, stored on the non-transient computer readable storage medium, for identifying a current position of a vehicle on a chart wherein a scale varies throughout the chart;
program code, stored on the non-transient computer readable storage medium, for determining whether the current position of the vehicle is on a path between two points in a plurality of points;
program code, stored on the non-transient computer readable storage medium, for presenting a first indicator at a first location on the chart indicating a position of the vehicle on the path relative to the two points responsive to a determination that the current position is on the path; and
program code, stored on the non-transient computer readable storage medium, for presenting a second indicator on a second location on the chart, wherein the second indicator indicates the position of the vehicle relative to the second location responsive to an absence of a determination that the current position is on the path.

### Claim 17 (depends on 16)

The non-transient computer program product of claim 16, wherein the path between the two points comprises a line and a width on each side of the line.

### Claim 18 (depends on 17)

The non-transient computer program product of claim 17 further comprising:
receiving a user input for the width.
