SPECIAL NOTE: As soon as the NAV1 radio is tuned to a valid ILS frequency, the VOR/GPS
switch changes to VOR and the autopilot to NAV ARM mode. If a valid ILS frequency is in
range, the autopilot will follow it´s localizer beam. Valid ILS frequencies are between 108.10
and 111.95 and the decimal part starts with an odd digit: 108.10, 108.15, 108.30, 108.35,
108.50, ..., 108.95, 109.10, 109.15, ..., 111.95.
