First Claim
Patent Images
1. A display apparatus for an aircraft comprising:
- a) an electronic display unit having,1) a display screen,2) a flight path vector symbol displayed on said screen,3) a speed error tape displayed on said screen, said tape having a first end and a second end, said first end adjacent said flight path vector symbol, said tape extending from said symbol to said second end,4) at least one speed bug positioned adjacent to said tape, each of said bugs representative of an associated reference speed, and,5) whereas the position of said speed bug relative to said first end of said tape is indicative of the difference between a current speed of said aircraft and said associated reference speed and once the associated reference speed is achieved said bug vanishes.

Abstract
An aircraft display combines speed error tapes and multiple speed reference bugs to produce a display which reduces pilot workload. The length of the speed error tape is indicative of the difference between a current aircraft speed and a reference speed. Multiple reference bugs are adjacent to the error tape and are indicative of the difference between the current aircraft speed and other selected reference speeds. The reference bugs move along the error tape thereby communicating the status of the current aircraft speed relative to the multiple reference speeds. The display reduces the need for the pilot to scan and analyze numerous instruments for the same information.

11. An information display device for vehicles comprising:
-
a) electronic display means for displaying information to an operator, said display means having; 1) a display screen; b) an error tape displayed by said display means on said display screen, the length of said tape being variable and representative of a difference between a current vehicle parameter and a primary reference value; and
,c) at least one reference bug displayed on said display screen, said bugs positioned adjacent said tape, said bugs being moveable along the length of said tape, the position of each of said bugs along said tape indicative of a difference between said current aircraft parameter and a secondary reference parameter associated with each of said bugs and once the reference parameter is achieved said at least one reference bug vanishes. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A vehicle comprising:
-
a) a frame; b) an engine support by said frame; and
,c) an electronic display supported by said frame, said display having, 1) a display screen, 2) a flight path vector symbol displayed on said screen, 3) a speed error tape displayed on said screen, said tape having a first end and a second end, said first end adjacent said flight path vector symbol, said tape extending from said symbol to said second end, 4) at least one speed bug positioned adjacent to said tape, each of said bugs representative of an associated reference speed, and, 5) whereas the position of said speed bug relative to said first end of said tape is indicative of the difference between a current speed of said aircraft and said associated reference speed and once the associated reference speed is achieved said bug vanishes.
