DIGITAL AUDIO PANEL
The EMB-145 is equipped with three individual Digital Audio Panels
(DAP), one each for the captain, copilot and observer.
This unit allows each flight crew member to select an individual
transceiver, the intercommunication function further permitting
individual selection and audio level adjustment of the following
communications equipment:
x
VHF
communication;
x
Crew/ramp
station
intercommunication;
x
Passenger
address;
x
Reception and amplification of the NAV/COM audio signals.
NORMAL MODE
In the normal mode, each flight crew member may select one COM
transceiver (VHF COM 1, VHF COM 2, VHF COM 3 or HF), the
interphone function and, simultaneously, several audio receivers
(COM 1, 2 and 3, HF, NAV 1 and 2, ADF 1 and 2, and DME 1 and 2).
Also, the unit may provide volume control for each radio equipment,
microphone selection between Boom and Mask (Oxygen Masks), and
audio output selection between Speakers and Headphones.
Other features are the capability to filter the NDB/VOR audio signals,
attenuating morse code or voice signals. Finally, Normal Mode allows
marker beacon audio sensitivity control, which also may silence
temporarily that type of signal.
EMERGENCY MODE
The pilot’s, copilot’s and observer’s digital audio panels are supplied
by ESS BUS 1, ESS BUS 2 and DC BUS, respectively. The
emergency mode must be selected in case power supply fails to come
to pilot’s or copilot’s digital audio panel, which does not mean that
there is a fault of the supplying bus. Selecting the pilot's DAP EMER
button automatically causes the pilot to be connected to COM 1 and
NAV 1 and selecting the pilot's DAP EMER button automatically
causes the copilot to be connected to COM 2 and NAV 2. The others
buttons of the DAP that is in emergency mode will be disabled. These
configurations are emergency modes that assure communication
continuance. Only for the observer’s DAP there is no alternative
means to keep communication capability once its normal power supply
is interrupted.
The interphone function will also be lost.
