Abstract
Abstract An aircraft display and control system includes a primary flight director and a head-up display. A flight management system computer generates a current aircraft velocity vector reticle, a desired aircraft velocity reticle, a speed reticle, an acceleration reticle, and a pitch reticle. The flight management system computer conformably generates a waypoint icon in the pilot's view through the windshield superimposed upon the position in the view of the geographic location and altitude of the actual waypoint.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
59 words
A primary flight display, comprising: a flat-panel color display device; a flight director reticle displayed on the display device indicating a desired aircraft velocity vector computed by an autopilot from an operator-entered desired flight path and indicating required pitch and roll commands; and a flight path angle reticle displayed on the display device indicating a current aircraft velocity vector.
Claim 2
Dependent Claim
59 words
A primary flight display, comprising: a flat-panel color display device; a flight director reticle displayed on the display device indicating a desired aircraft velocity vector computed by an autopilot from an operator-entered desired flight path and indicating required pitch and roll commands; and a flight path angle reticle displayed on the display device indicating a current aircraft velocity vector.
Claim 3
Dependent Claim
27 words
A primary flight display as recited in claim 1, comprising a speed reticle displayed on the display device indicating current speed error compared to a desired value.
Claim 4
Dependent Claim
23 words
A primary flight display as recited in claim 1, comprising a pitch reticle displayed on the display device indicating current aircraft pitch attitude.
Claim 5
Dependent Claim
26 words
A primary flight display as recited in claim 1, comprising a longitudinal acceleration reticle displayed on the display device indicating acceleration along the current flight path.
Claim 6
Dependent Claim
80 words
A primary flight display, comprising: a flat-panel color display device; a flight director reticle displayed on the display device indicating a desired aircraft velocity vector; and a flight path angle reticle displayed on the display on the display device indicating a current aircraft velocity vector, wherein the flight director reticle comprises a first reticle including a pair of quarter-circles indicating desired vertical aircraft velocity vector and a second reticle including a pair of quarter-circles indicating desired horizontal aircraft velocity vector.
Claim 7
Dependent Claim
80 words
A primary flight display, comprising: a flat-panel color display device; a flight director reticle displayed on the display device indicating a desired aircraft velocity vector; and a flight path angle reticle displayed on the display on the display device indicating a current aircraft velocity vector, wherein the flight director reticle comprises a first reticle including a pair of quarter-circles indicating desired vertical aircraft velocity vector and a second reticle including a pair of quarter-circles indicating desired horizontal aircraft velocity vector.
Claim 8
Independent Claim
88 words
A method for displaying information to an aircraft pilot, comprising the steps of: receiving operator-entered inputs specifying a desired flight path; generating first display signals representative of a desired aircraft velocity vector computed by an autopilot from the operator-entered inputs, said first display signals indicating required pitch and roll commands; generating second display signals representative of the current aircraft velocity vector; and simultaneously displaying on a flat-panel display device a flight director reticle and a flight path angle reticle respectively generated from the first and second display signals.
Claim 9
Independent Claim
