Description :
This is a Master Indicator used in the N-1 Compass System, a remote-indicating, gyro-stabilized navigation system employed by the U.S. Air Force during the 1950s and 1960s.
The N-1 Compass System was designed for all-latitude operation, making it a cutting-edge navigation tool at the time.
Aircraft Usage:
The N-1 system was installed at the navigator's station and was commonly used in the following U.S. Air Force aircraft:
- B-52 Stratofortress (early models) – Strategic bomber
- C-130 Hercules – Military transport aircraft
- KC-135 Stratotanker – Aerial refueling tanker
System Features:
- Remote-Indicating: Displays directional information from a remotely located sensor.
- Gyro-Stabilized: Uses a gyroscope to provide stable and accurate readings.
- All-Latitude Operation: Unlike standard magnetic compasses, the N-1 could function effectively at any latitude, improving navigational reliability in polar regions.
Historical Reference:
The KC-135 Flight Manual (1966 edition) includes an illustration of the N-1 Indicator, showing its design and integration within the aircraft's navigation system.
This instrument represents a significant advancement in mid-20th-century aviation technology, aiding in precise navigation for long-range military operations.
