Bendix-King Avionics
Paket (Radios)
The Piper Cheyenne is equipped with a complete avionics suite, the
„Silver Crown Plus“ series by Bendix-King. This suite is composed of
the KMA 28 Audio Panel, two KY 196A VHF communication receivers,
two KY 53 navigations receivers, two KR 87 ADF receivers, and two KT
76C mode C transponders.
1: DME Selector 3: Active Transponder Selector
2: AP-FD-Avionics Master Switch 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 beacon 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 sour-
ces, and it also contains a DME hold function. For DME hold, first 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.
