Chapter 10: Aircraft Systems › Direction Indicating Instruments › Remote Indicating Slaved Gyro Compass (Flux Gate Compass)
Flux Gate Compass) An elaborate and very accurate method of direction indication has been developed that combines the use of a gyro, a magnetic compass, and a remote indicating system. [Figure 10-82] It is called ... slaved gyro compass or flux gate compass system. A study of the gyroscopic instruments section of this chapter assists in understanding this device. A gyroscopic direction indicator is augmented by magnetic direction information from a remotely located compass. The type…
