ABSTRACT:
A liquid crystal display flight indicator unit having the capability to display a horizontal situation indicator (HSI) or an attitude direction indicator (ADI) on the viewing area of the same unit. Signals from existing aircraft electronics are processed to determine whether the incoming signal is an HSI or ADI graphical image to be displayed on the viewing area. A unique component layout is described to enable HSI and ADI to be contained within a unit having a chassis size not larger than previously known HSI and ADI units.
