Methods and systems are provided for displaying an unusual attitude of an
aircraft in a head-up display system. The system comprises a projection
unit configured to project the unusual attitude of the aircraft and a
processor coupled to the LCD projection unit. The processor is configured
to control the LCD projection unit during the unusual attitude of the
aircraft to produce an attitude indicator of the aircraft and a horizon
symbol. The horizon symbol divides the attitude indicator into a first
region having a first display characteristic and a second region having a
second display characteristic different from the first display
characteristic. The first display characteristic is substantially uniform
throughout the first region, and the first region indicates a ground with
respect to the aircraft.
