System and method for confirming received taxi instructions
A method and system are described for enhancing ground situational awareness to an aircrew via an alphanumeric display of an air traffic control ground clearance, including displaying a symbol for each stage of the clearance. A crewmember may accept or change each stage via a graphical user interface within the alphanumeric display.
1. A system for modifying autogenerated displayed taxi instructions to a crewmember of an aircraft, comprising:
a display located on board the aircraft for manual use by the crewmember, where the display shows:
a series of alphanumeric symbols, each representing an individual pathway segment;
a graphical user interface with a selection box for each individual alphanumeric symbol; and
a processor configured to:
receive a taxi destination that is manually entered by the aircraft crewmember;
identify the initial location of the aircraft;
autogenerate taxi instructions made up of a series of pathway segments to direct the aircraft from the initial location to the taxi destination;
accept an approved pathway segment that is manually selected by the crewmember using the selection box, where a manually accepted taxi pathway is created that comprises the pathway segments between the initial location and the approved pathway segment;
delete a declined pathway segment that is manually de-selected by the crewmember, where the pathway segments between the declined pathway segment and the taxi destination are deleted from the taxi instructions;
autogenerate a revised taxi pathway comprising a series of alternative pathway segments between the approved pathway segment and the taxi destination;
revise the taxi instructions to combine the manually accepted taxi pathway and the revised taxi pathway; and
modify a graphic display of the alphanumeric symbols to indicate acceptance of the revised taxi instructions.
2. The system of claim 1 wherein the processor is further configured to:
delete a declined pathway segment when a de-selection box for the alphanumerical symbol representing the declined pathway segment is selected.
3. The system of claim 1 wherein the processor is further configured to:
delete a declined pathway segment when the selection box for the alphanumerical symbol representing the declined pathway segment is selected twice.
4. The system of claim 1 wherein the processor is further configured to:
display a text box for manual entry of the taxi destination.
5. The system of claim 1 wherein the display is further configured to:
display a moving map including the pathway segments and the aircraft.
6. A system for modifying autogenerated displayed taxi instructions to a crewmember of a vehicle, the taxi instructions defining a plurality of pathways, the system comprising:
a display configured to display:
a series of alphanumeric symbols, each representing an individual pathway segment along the taxi instructions;
a graphical user interface with a selection box for each individual alphanumeric symbol; and
a processor configured to:
accept an approved pathway segment that is manually selected by the crewmember using the selection box, where a manually accepted taxi pathway is created that comprises the pathway segments between the initial location and the approved pathway segment;
delete a declined pathway segment that is manually de-selected by the crewmember, where the pathway segments between the declined pathway segment and the taxi destination are deleted from the taxi instructions; and
modifying a graphic display of the alphanumeric symbols to indicate acceptance of the revised taxi instructions.
7. The system of claim 6 wherein the processor is further configured to:
display a text box for manual entry of a taxi destination.
8. A method for modifying autogenerated taxi instructions using a display device onboard an aircraft, comprising:
receiving a taxi destination that is manually entered by an aircraft crew;
identifying the initial location of the aircraft;
autogenerating taxi instructions made up of a series of pathway segments to direct the aircraft from the initial location to the taxi destination;
serially displaying a series of alphanumeric symbols representing each individual pathway segment along the taxi instructions;
displaying a graphical user interface with a selection box for each individual alphanumeric symbol;
accepting an approved pathway segment by manually selecting its selection box, where a manually accepted taxi pathway is created that comprises the pathway segments between the initial location and the approved pathway segment;
deleting a declined pathway segment by manually de-selecting its selection box, where the pathway segments between the declined pathway segment and the taxi destination are deleted from the taxi instructions;
autogenerating a revised taxi pathway comprising a series of alternative pathway segments between the approved pathway segment and the taxi destination;
revising the taxi instructions to combine the manually accepted taxi pathway and the revised taxi pathway; and
modifying a graphic display of the alphanumeric symbols to indicate acceptance of the revised taxi instructions.
9. The method of claim 8 , further comprising:
deleting a declined pathway segment when a de-selection box for the alphanumerical symbol representing the declined pathway segment is selected.
10. The method of claim 8 , further comprising:
deleting a declined pathway segment when the selection box for the alphanumerical symbol representing the declined pathway segment is selected twice.
11. The method of claim 8 the method further comprising:
displaying a text box for manual entry of a taxi destination.
12. The method of claim 8 , further comprising:
displaying a moving map including the pathway segments and the aircraft.
