Systems and methods for improving positional awareness within an airport moving map
Systems and methods for displaying a location reference indicator (LRI) associated with an ownship icon are provided. In various embodiments, an airport moving map (AMM) is displayed, and the ownship icon is displayed in the AMM, where the ownship icon represents the ownship. A degree of zoom of the AMM is determined. In response to a determination that the degree of zoom is not within a range of center referenced threshold values, a first LRI is displayed that indicates that the icon representing the ownship is not to scale with other objects displayed in the AMM. In response to a determination that the degree of zoom is within the range of center referenced threshold values, a second LRI is displayed.
1. A method for displaying a location reference indicator (LRI) associated with an ownship icon, the method comprising:
displaying an airport moving map (AMM);
displaying the ownship icon in the AMM, the ownship icon representing an ownship;
determining a degree of zoom of the AMM;
displaying, in response to a determination that the degree of zoom is not within a range of center referenced threshold values, a first LRI that indicates that the icon representing the ownship is not to scale with other objects displayed in the AMM; and
displaying, in response to a determination that the degree of zoom is within the range of center referenced threshold values, a second LRI,
wherein:
the first LRI is displayed substantially non-centrally within the ownship icon, and
the second LRI is displayed substantially centrally within the ownship icon.
2. The method of claim 1 , wherein the first LRI is displayed substantially forward within the ownship icon.
3. The method of claim 1 , wherein the first LRI is displayed over the nose of the ownship icon.
4. The method of claim 1 , wherein only one of the first LRI or second LRI is displayed.
5. The method of claim 1 , wherein the second LRI is not displayed.
6. A system for displaying a location reference indicator (LRI) associated with an ownship icon, the system comprising:
a display;
an airport moving map (AMM) database that includes a map of an airport; and
an airport moving map generating system (AGS) communicatively coupled to the display and the AMM database, the AGS configured to:
receive the map of the airport and an ownship position and command the display to render an AMM that includes the ownship icon representing the ownship position on the map of the airport,
determine a degree of zoom of the AMM,
generate, in response to a determination that the degree of zoom is not within a range of threshold values, a first LRI that indicates that the ownship icon is not to scale with other objects displayed in the AMM, and
generate, in response to a determination that the degree of zoom is within the range of threshold values, a second LRI, wherein:
the first LRI is displayed substantially non-centrally within the ownship icon, and
the second LRI is displayed substantially centrally within the ownship icon.
7. The system of claim 6 , wherein the AGS commands the display to render the AMM such that the first LRI is displayed substantially forward within the ownship icon.
8. The system of claim 6 , wherein the AGS commands the display to render the AMM such that the first LRI is displayed within a nose of the ownship icon.
9. The system of claim 6 , wherein the AGS commands the display to render the AMM such that only one of the first LRI or second LRI is displayed.
10. The system of claim 6 , wherein the AGS commands the display to render the AMM such that the first LRI is not displayed.
11. The system of claim 6 , wherein the AGS commands the display to render the ownship icon such that the dimensions of the ownship icon are constant.
