ABSTRACT:
An aircraft attitude display format which maintains the horizon reference line always in view and which presents the pilot with multiple indications of aircraft attitude differing from level flight. The multiple indications include attitude registration along an angular scale and shape change of the horizon reference line. The display format has the appearance of a fish-eye lens derived optical image and is preferably placed in this form by electronic image processing--which is exemplified by an included mathematical discussion and computer code listing software. Provisions for other data display are also disclosed. Use of the display format in a panel instrument or CRT-based system including the HUD configuration are contemplated.
