Abstract: A collimated head up display of pitch related information for an aircraft operator. A generated pitch signal combines a gyroscope signal referenced to the airframe with an inertial signal referenced to the head up display or combiner screen. A pitch error signal representing the difference between the generated pitch signal and the inertial pitch signal is limited and integrated to develop a pitch correction signal which is added to the gyroscope signal. Reference of the inertial signal to the combiner screen of the display eliminates static alignment errors. The pitch correction signal may be selected for display during alignment of the combiner screen.
