Abstract

A system and method of conveying missed approach procedures to a pilot are provided. The system and method include rendering a graphic representation of at least one leg of the missed approach procedure on a display. A determination is made as to whether the aircraft is at least substantially flying the at least one leg of the missed approach procedure. At least one visual characteristic of the rendered graphic is selectively varied based on the determination of whether the aircraft is at least substantially flying the at least one leg of the missed approach procedure.

Claims

1. A method of conveying missed approach procedures to a pilot, comprising the steps of:

rendering a graphic representation of at least one leg of the missed approach procedure on a display;

determining, in a processor, whether the aircraft is at least substantially flying the at least one leg of the missed approach procedure; and

selectively varying, in response to one or more commands from the processor, at least one visual characteristic of the rendered graphic representation of the at least one leg of the missed approach procedure based on the determination of whether the aircraft is at least substantially flying the at least one leg of the missed approach procedure,

wherein;

the missed approach procedure comprises a plurality of legs; and

the rendered graphic includes a plurality of icons, each icon representative of one of the plurality of legs of the missed approach procedure.

2. The method of claim 1, further comprising:

determining when the aircraft has at least substantially flown the at least one leg of the missed approach procedure represented by the rendered graphic; and

varying the at least one visual characteristic of the rendered graphic when the aircraft has at least substantially flown the at least one leg of the missed approach procedure.

3. The method of claim 1, further comprising:

selectively generating a sound based on the determination of whether the aircraft is at least substantially flying the at least one leg of the missed approach procedure.

4. The method of claim 1, further comprising:

rendering text representative of the at least one leg of the missed approach procedure.

5. The method of claim 1, wherein the visual characteristic includes one or more of color, relative intensity, and relative size.

6. The method of claim 1, further comprising:

determining that a leg of the missed approach procedure is to be flown; and

rendering the leg of the missed approach procedure that has been determined is to be flown with a visual characteristic that differs from other legs of the missed approach procedure.

7. The method of claim 6, wherein the visual characteristic includes one or more of color, relative intensity, and relative size.

8. The method of Claim 6, further comprising:

rendering text representative of the leg of the missed approach procedure that has been determined is to be flown.

9. The method of claim 1, further comprising:

receiving a user input; and

in response to the user input, automatically flying the at least one leg of the missed approach procedure that is represented by the rendered graphic.

10. The method of claim 9, further comprising:

loading the at least one leg of the missed approach procedure that is represented by the rendered graphic into an active flight plan.

11. A display system for conveying missed approach procedures to a pilot, comprising:

a display configured to render a graphic representation of at least one leg of the missed approach procedure; and

a processor coupled to the display, the processor configured to (i) command the display device to render the graphic representation of the at least one leg of the missed approach procedure and (ii) determine whether the aircraft is at least substantially flying the at least one leg of the missed approach procedure and, in response to the determination, to selectively command the display to vary at least one visual characteristic of the graphic representation of the at least one leg of the missed approach procedure rendered on the display,

wherein;

the missed approach procedure comprises a plurality of legs; and

the rendered graphic includes a plurality of icons, each icon representative of one of the plurality of legs of the missed approach procedure.

12. The system of claim 11, wherein the processor is further operable to:

determine when the aircraft has at least substantially flown the at least one leg of the missed approach procedure represented by the rendered graphic; and

command the display to vary the at least one visual characteristic of the rendered graphic when the aircraft has at least substantially flown the at least one leg of the missed approach procedure.

13. The system of claim 11, further comprising:

a speaker coupled to the processor and responsive to a signal to generate an audible sound,

wherein the processor is further operable, in response to the determination of whether the aircraft is at least substantially flying the at least one leg of the missed approach procedure, to selectively supply the signal to the speaker.

14. The system of claim 11, wherein:

the display is further configured to render text; and

the processor is further operable to command the display to render text representative of the at least one leg of the missed approach procedure.

15. The system of claim 11, wherein the visual characteristic includes one or more of color, relative intensity, and relative size.

16. The system of claim 11, wherein the processor is further operable to:

determine that a leg of the missed approach procedure is to be flown; and

command the display to render the leg of the missed approach procedure that it has determined is to be flown with a visual characteristic that differs from other legs of the missed approach procedure.

17. The system of claim 11, further comprising:

a user interface coupled to the processor and responsive to user input to supply a user selection signal;

wherein the processor is responsive to the user selection signal to load the at least one leg of the missed approach procedure that is represented by the rendered graphic into an active flight plan.
