1. DESCRIPTION
The SC 063 Sight Compass (Figure 4) is a modified version of a standby type Aircraft
Compass which has had its compensating assembly removed and a collimator sight
attached.
Modified features include:
A.
Reversed magnetic polarity, which permits the operator of the Sight Compass to view
the aircraft being checked from the front. This makes communications (hand signals)
between the Aircraft occupant and the Sight Compass operator convenient.
B.
Attached to the front of the Sight Compass is a combination magnifying lens (to
increase the readability of the dial) and a collimating lens (to ensure precise sighting
alignment).
C.
Attached to the rear of the Compass is an adjustable Sight Lens. The lens is precisely
aligned to ensure that the overall accuracy of the dial falls within ± 1°.
D.
The Compass is mounted on a bracket, which can be attached to a monopod assembly
(supplied with the Sight Compass).
E.
The Sight Compass is painted red and has a caution label attached to it to prevent
inadvertent installation in an Aircraft.
F.
The SC 063 Sight Compass is packaged in a protective carrying case.
