System and method for increasing visibility of critical flight information on aircraft displays
First Claim
1. A system for increasing visibility of flight information on a visual display, comprising:
- a flight management information unit, said flight management information unit operable to determine at least one of a current position, direction, pitch and path of an aircraft;
a data storage unit, said data storage unit operable to store target data and terrain data; and
a processing unit coupled to said flight management information unit, said processing unit operable to;
receive said at least one of current position, direction, pitch and path of said aircraft;
receive said target data and said terrain data;
generate a first plurality of control signals for a visual display, said first plurality of control signals representing a flight control symbol for said visual display;
generate a second plurality of control signals for said visual display, said second plurality of control signals representing a second symbol for said visual display, said second symbol associated with said pitch of said aircraft;
generate a third plurality of control signals for said visual display, said third plurality of control signals representing a gap in said second symbol for said visual display, said gap associated with a position of said flight control symbol on said visual display; and
generate said third plurality of control signals for said visual display so as to adjust a transparency of said gap and enhance a visibility of at least one of said target data and said terrain data on said visual display.

Abstract
System and method increase the visibility of critical flight information on electronic displays. An aircraft display system includes a processing unit, a flight management system, a navigation system, a database for storing target data and terrain data, a graphics display generator, and a visual display. The flight management system and/or the navigation system provide real-time aircraft operational and flight control information. The processing unit directs the graphics display generator to generate graphic control signals for the visual display, which increase the transparency of a segment of a zero pitch reference line in the vicinity of a flight path marker on the display.
