1: DME Selector 2: AP-FD-Avionics Master Switch
3: Active Transponder Selector 4: Copilot HSI Nav Source Selector
The Avionics Master Switch (2) controls the avionics bus and supplies COM1/2,
NAV1/2, ADF1/2, Transponder 1/2, the autopilot, the RMI´s and the marker bea-
con and glideslope indicators with power.
The DME selector (1) controls the DME readout on the pilot´s HSI. It can be set to
receive the DME signal from either NAV1 or NAV2 sources, and it also contains a
DME hold function. For DME hold, rst tune the desired NAV radio to the DME
signal you want to receive and hold. Next, select the respective NAV radio via the
DME selector (1), then switch the DME selector (1) to the HOLD position. You may
now tune a different station on the respective NAV radio, while the original DME
signal is still displayed. Note that there is no indication about which frequency
is used for the DME readout. To cancel DME hold, switch the DME selector (1) to
either NAV1 or NAV2 position.
The active Transponder Selector Switch (3) toggles the status of the two KT 76C
transponders. The selected transponder is made the active one, while the other
one is automatically switched to standby mode.
The Copilot HSI Nav Source Selector Switch (4) selects either NAV1 or NAV2 as the
data source for the Copilot´s HSI.
