Abstract

Abstract:

A new algorithm is presented for attitude indicator used in an aircraft cockpit to reduce the consumed time for graphics switching. The algorithm gets the coordinates of pixels in a horizontal scanning line and fills the graph with horizontal or vertical lines. This way, the horizontal buffer is not needed. Graphics in the attitude indicator are switched using less memory and less calculation time than the original algorithm.

Key words: filling algorithm , attitude indicator , electronic integrative display
