Aircraft operating and position information display system and method
First Claim
1. A method of displaying aircraft operating and position information with an electronic display unit, comprising:
- determining a position of a first aircraft at an airport;
determining a ground optimum speed range of the first aircraft, with a performance model;
determining a first aircraft ground speed of the first aircraft with a speed sensor;
generating display signals as a function of the first aircraft position, the first aircraft ground optimum speed, and the first aircraft ground speed;
displaying on a screen of the display unit a map of the airport, including geographic locations and dimensions of runways and taxiways, from map data in an airport database;
displaying a first aircraft symbol on the map, the first aircraft symbol displayed in a position on the map indicative of position of the first aircraft; and
displaying an optimum speed range symbol, the optimum speed range symbol having a lower bound end and a higher bound end, on the map; and
wherein the optimum speed range symbol is displayed in a position on the map such that the first aircraft symbol is between the lower bound end and the higher bound end when the first aircraft speed is within the optimum speed range.

Abstract
A method of displaying aircraft operating and position information with an electronic display unit comprises determining a position of a first aircraft at an airport; determining an optimum speed range of the first aircraft; determining a first aircraft speed of the first aircraft; displaying on a screen of the display unit a map of at least part of the airport; displaying a first aircraft symbol on the map, the first aircraft symbol displayed in a position on the map indicative of position of the first aircraft; and displaying an optimum speed range symbol having a lower bound end and a higher bound end in a position on the map such that the first aircraft symbol is between the lower bound end and the higher bound end when the first aircraft speed is within the optimum speed range.
