26 channels in 133.3 to 136.0 MHz
What is the frequency range of TACAN?
1000 MHz band. selection by pre set channels 1 - 126
What are the frequency ranges for VOR?
108 to 117.95

Activated by an inertial switch or manual switch to on.
Can't be disarmed
Can be reset by going ON then ARM
What system is in place for the erection of AIs?
Two mercury switches which sense movement in the pitch and roll axes.
These switches then operate torque motors which will cause gyroscopic precession to level the platform.
What is the operating principle of ILS?
