Using a ILS test signal generator verify proper deviation of the LOC/GS deviation
indicators on the SN3500. Tune the NAV1 to match the ILS test signal generator
frequency (usually 108.1 MHz.). Select LOC 1 on the SN3500. Adjust the signal
generator to verify the following indications on the SN3500 LOC deviation
indicator, center, 2 dots fly left, 2 dots fly right, and LOC flagged. Adjust the signal
generator to verify the following indications on the SN3500 GS deviation indicator,
center, 2 dots fly up, 2 dots fly down, and GS flagged. Repeat for NAV2.
