Abstract
Approach Decision Display and associated methods and systems are disclosed. A method and system in accordance to one embodiment of the disclosure includes a display of operationally-relevant information for final approach and landing on a cockpit graphical display. Approach Decision Display System (ADDS) provides, in a graphical display, dynamic decision parameters as a function of the health of required equipment for the selected approach and the aircraft's ability to execute the approach and landing.
Claims20
A final approach decision display device comprising:
- quasi-static referents comprising at least one of a ground level indicator, a runway indicator, a touchdown zone elevation tag, an approach path indicator, a missed approach altitude tag, a required visibility tag, a runway visual range tag, a thrust retard capability indicator, and an autopilot disconnect cue;
- dynamic referents comprising at least one of an own-ship symbol, an approach minima tag, an approach minima indicator, an approach minima alert tag, an approach minima alert indicator, a radio altitude tag, a radio altitude indicator, an approach-reference distance tag, an actual runway visual range tag, and a missed approach point symbol;
- and
- status referents comprising at least one of an approach name, a landing clearance status tag, and an autoland status tag wherein said quasi-static, said dynamic, and said status referents are transformed into a graphical depiction of an airplane's landing performance capability.
A system comprising:
- an approach decision display system, said approach decision display system providing operationally-relevant information for final approach and landing;
- a flight management system operatively connected to said approach decision display system;
- a cockpit graphics display system operatively connected to said approach decision display system;
- an aircraft control system operatively connected to said approach decision display system;
- a communications system operatively connected to said approach decision display system
- a navigation system operatively connected to said approach decision display system;
- and
- a control input device operatively connected to said approach decision display system;
- and
- a graphical display of operationally-relevant information displayed on said cockpit graphical display system, wherein said operationally-relevant information comprises of a quasi-static referent, a dynamic referent, and a status referent, further wherein said quasi-static referent, said dynamic referent, and said status referent are transformed into a graphical depiction of an airplane's landing performance capability.
A method of providing a tool for approach decision making on a cockpit display system, comprising:
- initiating the ADDS system;
- receiving flight plan information;
- receiving landing clearance information;
- receiving system performance and system health information;
- processing received said flight plan, said landing clearance, said system performance, and said system health information for display;
- displaying operationally-relevant information wherein said operationally-relevant information comprises of processed information from said flight plan, said landing clearance, said system performance, and said system health information;
- monitoring for landing performance capability degradation;
- updating dynamic referents continuously;
- and
- updating the display of said operationally-relevant information.
