SECTION 7
AIRPLANE
&
SYSTEMS DESCRIPTIONS
If the airplane has a heated stall warning system, the vane-type unit in
the wing leading edge is equipped with a heating element. The heated part
of the system is operated by the PITOT HEAT switch, and is protected by
the PITOT HEAT circuit breaker.
The stall warning system should be checked during the preflight
inspection by momentarily turning on the master switch and actuating the
vane in the wing. The system is operational if a continuous tone is heard on
the airplane speaker as the vane is pushed
upward.
AVIONICS SUPPORT EQUIPMENT
The airplane may, at the owner's discretion, be equipped with various
types of avionics support equipment such as an audio control panel,
~
.
microphone-headsets, and static dischargers. The following paragraphs
discuss these items.
AUDIO CONTROL PANEL
Operation of radio equipment is covered in Section 9 of this handbook.
When one or more radios are installed, a transmitter/audio switching
system is provided (see figure 7-12). The operation of this switching
system is described in the following paragraphs.
TRANSMITTER SELECTOR SWITCH
A rotary type transmitter selector switch, labeled XMTR SEL, is
provided to connect the microphone to the transmitter the pilot desires to
use. To select a transmitter, rotate the switch to the number corresponding
to that transmitter. The numbers
1,
2 and 3 above the switch correspond to
·the top
,
second, and third transceivers in the avionics stack.
The audio amplifier in the NA V / COM radio is required for speaker and
transmitter operation. The amplifier is automatically selected, along with
the transmitter, by the transmitter selector switch. As an example, if the
number 1 transmitter is selected, the audio amplifier in the associated
NA V / COM receiver is also selected, and functions as the amplifier for ALL
speaker audio. In the event the audio amplifier in use fails, as evidenced by
loss of all speaker audio and transmitting capability of the selected
transmitter, select another transmitter. This should re-establish speaker
audio and transmitter operation. Since headset audio is not affected by
audio amplifier operation, the pilot should be aware
that,
while utilizing a
headset, the only indication of audio amplifier failure is loss of the selected
transmitter. This can be verified by switching to the speaker function
.
