Abstract
The present invention is directed to a system and methods, embodiments of which provide increased situation awareness information in an improved Synthetic Vision System (SVS). According to the present invention, a Primary Flight Display (PFD), a top-down view Multi-Function Display (MFD), and side-view Vertical Profile Display (VPD) are presented on one user interface with an input device, such as a transparent touch screen for quick and easy data entry. The present invention also provides color shading, such as red, to communicate areas where the aircraft may be in conflict with terrain or obstacles at a point in time in the future.
