AIDING PILOT PREVIEW, REHEARSAL, REVIEW, AND REAL-TIME VISUAL ACQUISITION OF FLIGHT MISSION PROGRESS

Embodiments of the invention permit flight paths (current and planned) to be viewed from various orientations to provide improved path and terrain awareness via graphical two- dimensional or three-dimensional perspective display formats. By coupling the flight path information with a terrain database, uncompromising terrain awareness relative to the path and ownship is provided. In addition, missed approaches, path deviations, and any navigational path can be reviewed and rehearsed before performing the actual task. By rehearsing a particular mission, check list items can be reviewed, terrain awareness can be highlighted, and missed approach procedures can be discussed by the flight crew. Further, the use of Controller Pilot Datalink Communications enables data-linked path, flight plan changes, and Air Traffic Control requests to be integrated into the flight display of the present invention.
Abstract: 
NASAs Langley Research Center has developed a synthetic 3D visualization flight display, which presents flight data information in an intuitive way using 3D computer graphic capabilities. The flight crew can preview and rehearse flight maneuvers in a realistic environment. The display also provides an unimpeded visualization of the surrounding environment in the case of inclement weather, enabling safer flying conditions. Flight crews can rewind/fast forward/pause to certain areas of an approach or go-around and discuss abort strategies or point out dangerous terrain. New pilots can safely train on upcoming flights because of the intuitive and easy-to-follow technology. Seasoned pilots will notice the current paper chart arrangement but with information presented in a quickly interpretable manner. Flight crews can use the technology as a refresher for destinations less frequently traveled. The technology is widely applicable for civilian, military, and even unmanned flights.
Benefits: 

Safety - Increased safety through better training and realistic terrain visualization

applications: 

The technology enables improved products for a variety of commercial and military applications:

Manned aerospace - flight plan display

Unmanned aerospace - real-time 3D environment

Oceanographic - synthetic 3D environment for rehearsing complex underwater exploration routes
