101-01200 - Barfield SC063 Compass Calibration Device

The SC063 is designed as a portable calibration device used to check the accuracy of mounted aircraft compasses. Unlike a standard compass, it has been specially re-screened and engineered to provide precise alignment and reliable readings. This tool helps ensure that aircraft magnetic compasses remain accurate, supporting safe navigation and compliance with maintenance standards.

Unlike a typical aircraft compass, the SC063 has had its compensating magnets removed and includes a collimating sight and magnifying lens. This prevents calibration offsets and ensures accurate readings under all conditions. The unit is not intended to be used as an aircraft compass in flight but as a calibration reference tool for ground use.

Setup is minimal. The unit mounts on a bracket that can be attached to a 5’ 6” monopod, which provides a stable reading height for the operator. The monopod can be adjusted so the compass aligns precisely with the operator’s line of sight, reducing the time required for calibration preparation.

All external parts, including the mounting bracket, monopod, and hardware, are constructed from non-magnetic materials. This design choice prevents interference with the SC063’s magnetic accuracy, ensuring that readings remain precise during calibration work.

The SC063 is engineered to be accurate to within ±1 degree. The magnifying lens improves dial readability, while the collimating sight guarantees proper alignment. This combination allows technicians to calibrate aircraft compasses with high confidence in the reliability of the readings.

Yes, the SC063 is designed to be lightweight, durable, and handheld for easy portability. It comes with a protective carrying case that keeps the device and its accessories secure during transportation, making it suitable for both field and hangar use.

No, the SC063 is not designed or approved for use as an aircraft compass. It is strictly a calibration device and should never be installed in an aircraft for navigation purposes. Its design and labeling specifically discourage such use.

The SC063 incorporates a collimating sight and an adjustable sight glass at the rear of the compass. These components ensure proper alignment, allowing technicians to transmit signals to and from the aircraft cockpit with improved precision.

Yes, the SC063 is supplied with a mounting bracket and monopod support. This hardware provides stability during calibration and can be adjusted so the sight compass aligns with the operator’s eye level. The accessories are built from materials that won’t compromise the unit’s magnetic accuracy.

The SC063 comes with a rugged, protective carrying case. This case is designed to safeguard the device during transport and storage, keeping all components organized and ready for use in the field.

The SC063 should be kept in its protective case in a clean, dry location away from extreme temperatures. Proper storage prevents damage to sensitive components and helps maintain calibration accuracy, extending the unit's service life.

The SC063 is largely maintenance-free but should be inspected periodically for dirt, dust, or physical damage. Keeping the sight glass and magnifying lens clean ensures clear readings. If the unit shows signs of wear, it should be serviced according to the manufacturer’s guidelines.

The SC063 is used by aircraft maintenance technicians, MRO providers, and aviation operators responsible for navigation system upkeep. It’s particularly useful during scheduled inspections or after compass-related repairs. By ensuring compass accuracy, the SC063 plays a key role in flight safety.
