An aircraft head up display system that displays a basic mode, an en route mode, or an approach/landing mode. When the aircraft attitude changes to predefined unusual attitude conditions, the display changes to an unusual attitude mode to indicate the unusual attitude condition. The display in the unusual attitude mode removes non-essential symbols and displays the aircraft air speed, altitude and attitude. The attitude display includes an unusual attitude ball display containing a horizon symbol, a series of simulated section lines to indicate an area below the horizon, a pitch ladder, a water line indicator, and a roll indicator.
