GENERAL INFORMATION
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.

2. DIMENSIONS AND WEIGHT
A. Length: 2.75 in. (7 cm)
B. Width: 2.36 in. (6 cm)
C. Height: 3.34 in. (8.5 cm)
D. Weight: 0.72 lbs. (0.325 Kg)
3. CAPABILITIES
The Sight Compass is a small, readily portable, convenient instrument which can be used to:
A. Determine the magnetic suitability of a Compass swinging area.
B. Check and layout Compass swinging bases.
C. Determine the magnetic heading of an Aircraft.
NOTE: Since the Sight Compass is used extensively when a prepared base is not
available, operating personnel should be familiar with its three uses and with
the method of checking its accuracy.
4. ACCESSORIES PROVIDED
A. A monopod assembly, which is provided in assorted lengths. Combinations of lengths
may be chosen to support the Sight Compass at the operator’s eye level. Although the
Sight Compass can be hand held, experience has shown that the use of the monopod
provides more stable sightings.
NOTE: All external parts of the Sight Compass, such as the mounting bracket and
monopod, have been selected to contain no materials which could affect the
magnetic accuracy of the Sight Compass. Any other support, such as a
camera tripod, must be carefully checked for the presence of any ferrous
materials before being used.
B. A case, which facilitates protecting and carrying the Sight Compass.
C. The reference laminated card described in page 1, paragraph 2.B.
