Not mentioned in the manual, which states
the F-5E Tiger II contains only the same basic navigation and communication avionics
as the real airplane does. UHF Comms are available, while VOR navigation is controlled
via the selector for mode and the NAV MHz / KHz controls on the pilot’s left side panel.
TACAN is selected using the controls below the comms radio beneath the radar.
There is no approach mode or ILS available in this aircraft, nor GPS or autopilot
