NAV1
The NAV1, is an important type of a radio navigation instrument.
The needles indicate the course line on the VOR and the glideslope on the ILS.
Flags indicate To/From (or off) and glideslope availability.
Adjustment of the course line on the instrument is communicated to the Flight Simulator.
This version contains five stepper motors to control the needles, the
flags and the compass rose (OBS).
This NAV1 now has a stronger FL20 motor for the OBS.
The NAV1 is only available as master instrument. An Interface Box is needed (see General concept).
The instrument is illuminated by (2) leds.
The NAV2 is similar to NAV1 but with less indicators, see NAV2.
