Operation
The VHF and/or HF communication systems are tuned to a SELCAL frequency that has been
assigned to a ground station.
When a ground station wants to talk to the flight crew, the ground station sends a SELCAL code
on the assigned frequency. The SELCAL unit monitors the VHF and HF communication systems
audio output channels.
When a SELCAL signal is received, the decoder checks the signal tones for the correct frequency,
sequence, amplitude, and duration.
GF0610_050
" SELCAL, SELCAL"
If all the parameters are met, a SELCAL HF or VHF advisory message will be displayed on EICAS
and the audio integrating system will command an aural message “SELCAL, SELCAL” in the flight
compartment speakers and headsets.
The pilot selects the respective VHF or HF system on the audio panel and when the Push-To-Talk
(PTT) switch is pushed, the EICAS message is cancelled.

RADIO ALTIMETER
The Radio Altimeter (RA) system provides airplane altitude above the terrain up to +2550 feet. The
RA system is comprised of two RA transceivers, each connected to two separate antennas. The
antennas are identical and dedicated, one for transmitting and the other for receiving. The antennas
are positioned on the bottom centerline of the fuselage to minimize performance degradation in turns
and prior to landing while in the flare on landing.

• EGPWS.
• FCUs.
• DAUs (to display processors for PFD displays).
Refer to FLIGHT INSTRUMENTS Chapter 11, for additional information on RA indications.

STATIC DISCHARGER
The airplane wings and tail sections contain static wicks installed to discharge static electricity,
reducing radio interference. They are installed at the following locations:
• Winglets/wingtips and ailerons.
• Elevators, rudder, vertical stabilizer, horizontal stabilizer and tail cone.
GF0610_053
There are two parts to each static discharge assembly: the static discharger and the mounting base.
If any are found missing during the walkaround, refer to the configuration deviation list of the AFM to
verify if you can dispatch.

COCKPIT VOICE RECORDER
The Cockpit Voice Recorder (CVR) is a crash survivable recording device that simultaneously
records four channels of audio data representing the cockpit acoustic environment. The system
consists of:
• CVR.
• Microphone monitor/control panel.
• Remote area microphone.
• Impact switch.
CVR LOCATION
The CVR retains the most recent two hours of recorded information in memory. Input is received
from each audio control panel and CVR area microphone. The CVR also receives digital data (GMT
time) from DAU #4 to synchronize the CVR with the flight data recorder.
