Solid State Vertical Scale Aircraft Engine Performance Indicator Group.
Abstract
The design work performed on a totally solid state engine performance instrument group is discussed. The particular application is a dual channel indicator with the parameter displayed as an analog bargraph with redundant numeric. The display medium is gallium arsenide phosphide (GaAsP) LED emitting light in the red spectrum. Emphasis is given to the bargraph drive and control circuitry, A/D conversion chips, pertinent LED developments and formats, a method of brightness control and instrument maintainability.
