Figure 11-7 Annunciator/Control Panel
Audio Panel
The audio panel has an amplifier located beneath the panel face. It amplifies the audio from the
ICS and the UHF, TACAN, and VOR receivers. The amplifier is energized immediately when
DC power is applied to the aircraft. Power to the amplifier is not affected by the AVIONICS
MASTER switch or the avionics control transfer system. Audio switches (sometimes called
"mixer switches"), located in the center of the audio panel, enable either normal or emergency
reception. When forward (ON) in the UHF, TACAN, and VOR position, audio from each radio is
amplified and sent to the respective headset. The center OFF position allows no audio to the
headset. The aft EMER AUDIO position is used only if the audio panel amplifier fails, in which
case the amplifier is bypassed. The resulting loss of volume can be compensated for by adjusting
the VOL knobs on the individual UHF, TACAN, and VOR control panels. The VOL knob on the
audio panel adjusts the volume of the amplified ICS, UHF, TACAN, and VOR audio. The VOL
knob is the only control for the individual pilot's ICS volume. Imbalance between ICS and the
UHF, TACAN, and VOR audio can be corrected by adjusting the VOL knobs on the individual
control panels (Figure 11-1).
Course Deviation Indicator (IND-350)
The course deviation indicator (CDI), located on the right side of the instrument panel in both
cockpits, is a secondary navigational instrument in the VOR/TACAN system. It assists the pilot
in interpreting the RMI and in maintaining a desired flight course. The OBS knob sets the
selected course. The CDI (deviation bar) indicates deviation from course. The TO-FROM
