  • Patent number: 4663968
    Abstract: Continuous display of pitch attitude beyond normal limits of plus or minus 20 degrees is provided by an extended pitch indicator whose operation is coordinated with a primary pitch indicator which provides pitch information through primary ascent and descent ranges (plus or minus 20 degrees). Operation of the extended pitch indicator is coordinated with operation of the primary pitch indicator in such a manner that the extended pitch indicator is hidden from view during flight maneuvers within the primary climb and dive ranges, but which is automatically exposed during flight maneuvers outside of the primary climb and dive ranges. In the preferred embodiment, the extended pitch indicator element is attached to the pitch gimbal and a horizon mask 15 interposed between the extended pitch indicator and the primary pitch indicator scale.
