The ADF comprises two independent systems. Each system consists of :
- one receiver 2RP1 (2RP2)
- one loop and sense antenna 3RP1 (3RP2).
In addition, the components given after control the system :
(Ref. Fig. 003)
-
the Radio Management Panel 1(2) (RMP) 1RG1 (1RG2)
-
the CAPT (F/O) Audio Control Panel (ACP) 2RN1 (2RN2)
-
the Multipurpose Control and Display Unit 1(2) (MCDU) 3CA1 (3CA2)

(a) In ROSE and ARC modes If you set the ADF/VOR/OFF switches on the EFIS control section of the FCU to ADF, this causes : display of the characteristics of the ADF 1 and/or 2 stations in the L and/or R lower corner of the ND (item 3) :
-type of station
-shape of the associated bearing display
-station identification or frequency
-tuning mode (nothing : automatically tuned, M : manually tuned
and R : if tuned by the RMP). A single pointer on the heading dial shows the bearing of the ADF 1, a double pointer that of the ADF 2 (item 2). All these data are shown in green except the tuning mode which is shown in white.
(b)
In ROSE NAV and ARC modes If you push the NDB pushbutton switch on the EFIS control section of the FCU, triangle symbols show the ADF stations (item 1).
(c)
In case of NCD, the station characteristics and associated pointer(s) go out of view.
(d)
In case of ADF 1 (2) fault, a red ADF warning message is shown in place of the station characteristics.

(2) On the VOR/ADF/DME RMI If you set the VOR/ADF selector switches (item 4) to ADF, the RMI indicates the ADF bearings :
-
a single pointer indicates the ADF 1 bearing (item 5)
-
a double pointer indicates the ADF 2 bearing (item 6). A warning flag comes into view to indicate system malfunction (item 7) . In this case, the related pointer is at the last valid position (item 8). If No Computed Data (NCD), the warning flag comes into view and the related pointer stays at the position corresponding to the last correct data.

(3) Audio control
(a)
The ADF receiver applies its audio output to the audio integrating system. This system controls and directs the output to the headsets and/or the loud speakers. The AMU controls the audio level through the ACP. On the ACP, the pilot must push the ADF1 (ADF2) pushbutton switch and adjust the related potentiometer to the correct audio level.
