MFR Model# SC063

Overview

The SC063 is a portable, self-contained calibration device used to check mounted aircraft compasses. This device consists of a modified aircraft compass which has been re-screened to indicate 180 degrees from normal. The SC063 allows the operator to stand facing the aircraft making it considerably easier to transmit signals to and from the aircraft cockpit. The SC063 is unique in that the compensating magnets have been removed and a combination magnifying lens and collimating sight added. The compensator has been removed so the compass indicates magnetic direction at all times and is not subject to calibration offsets. The magnifying lens increases the readability of the dial, and the collimating lens insures precise sighting alignment. Attached to the rear of the compass is an adjustable sight lens. The lens is precisely aligned to insure that the overall accuracy of the dial does not exceed +1.

The sight compass is painted red and a caution label is attached to prevent inadvertent installation in an aircraft. Each unit is painted red for clear identification, and must not, under any circumstances, be used as an aircraft compass.

The monopod support provides a stable reading while not requiring long setup times. The 5 foot monopod assembly is furnished in sections consisting of assorted lengths. Combinations of these lengths may be chosen to adjust the sight compass to the eye level of the operator.

All external parts were designed of materials which will not affect the magnetic accuracy of the sight compass.
