Claim 14:
15. A runway awareness and advisory system (RAAS) for an aircraft, comprising:
an output device;
a processor in operable communication with the output device, the processor configured to execute program instructions, wherein the program instructions are configured to cause the processor to:
receive airport map data from an airport mapping database including an identification of taxiways and runways;
receive flight plan data including a planned departure runway from a Flight Management System (FMS);
receive position data for the aircraft from a sensor system of the aircraft;
determine whether the aircraft is on ground and located on a taxiway or in air and aligned with a taxiway based on the position data and the airport map data;
determine whether the aircraft is taking off or on final approach based on data from the sensor system;
output, by the output device, a taxiway take-off or approaching taxiway message when the aircraft is determined to be taking off or on final approach and when the aircraft is determined to be located on the taxiway or aligned with the taxiway
upon a determination that the aircraft is on the ground:
determine whether the aircraft is taking off;
identify a current runway based on the position data;
identify an approaching intersecting runway that crosses the current runway,
output, by the output device, an approaching intersecting runway advisory message of the approaching intersecting runway when the comparison result indicates the current runway and the planned departure runway do not match, and the aircraft is determined not to be taking off, and
inhibit the approaching intersecting runway advisory message of the approaching intersecting runway when the aircraft is determined to be taking off, and the comparison result indicates the current runway and the planned departure runway match.
