Subtask 34-53-00-710-056-A ** ON A/C NOT FOR ALL

A. Operational Test of the ADF

ACTION	RESULT
1.On the center pedestal, on one ACP: push the ADF1 pushbutton switch. 2.On the RMP:
set an ADF local frequency . ADF-Frequency Selection ** ON A/C NOT FOR ALL	On the CAPT and F/O NDs: the ADF1 pointer moves and shows the station direction. the station identification or frequency comes into view in the left lower corner.
	In the loudspeakers: if the station set is a A1 station, you cannot hear the identification signal. Do step 3 if the station set is a A2 station, you can hear the identification signal. Go to step 4.
3.On the RMP1 (RMP2):
set the BF0 function. ADF-Frequency Selection ** ON A/C NOT FOR ALL	in the loudspeakers, you can hear the identification signal but it is weaker.
4.On the RMP1 (RMP2):
set a non local ADF station. ADF-Frequency Selection ** ON A/C NOT FOR ALL	On the CAPT and F/O NDs, the ADF1 pointer goes out of view.
	In the loudspeakers, no signal is heard.
