Module 13. Aircraft aerodynamics, structures and systems

When a compass is in the slave mode

  • the azimuth gyro will wander uncompensated
  • azimuth gyro will be corrected by long term monitoring of the flux valve
  • the azimuth gyro is slaved to the annunciator or synchroniser circuit

Explanation

In slaved (slave) mode the directional gyro's azimuth output is continuously monitored against the flux valve, which senses the Earth's magnetic field, and slowly corrected to remove gyro drift. This long-term magnetic monitoring keeps the heading accurate; in free (DG) mode the gyro would wander uncompensated.
