Abstract:
An integrated flight control indicator for providing visual information indicative of aircraft flight parameters, said integrated flight control indicator comprising:a) a sky arc;b) an earth arc visually distinguishable from said sky arc, said sky arc and said earth arc cooperating to generally define a circle, the relative lengths of said sky arc and said earth arc indicating pitch of the aircraft, the sky arc having a length greater than a length of the earth arc to indicate pitch up and the earth arc having a length greater than the length of the sky arc to indicate pitch down;c) a horizon line extending approximately between two intersections of said sky arc and said earth arc so as to provide a visual indication of the roll of the aircraft; andd) bank angle markers extending radially inward from two intersections of said sky arc and said earth arc to two ends of said horizon line, the angle between said bank angle markers and said horizon line varying with the pitch of the aircraft such that during level flight, the bank angle markers are co-linear therewith, during pitch down the bank angle markers angle up from said horizon line, and during pitch up, the bank angle markers angle down from said horizon line;e) wherein said sky arc and said earth arc provide a visual indication suitable for use in instrument panel displays, heads-up displays, and helmet-mounted displays.
