Communications Flashcards
Describe the Flight Interphone system
Permits communication between
-Captain
-First Officer
-3rd occupant
-Ground personal connected at the external power panel near the nose gear
Requires use of the INT (transmittion key and reception knob) controls on the Audio Control Panel (ACP)
Describe the Cabin Interphone System
-Permits communication between between flight deck and cabin
-Requires the use of the CAB (transmission key and reception knob) controls on the ACP
Describe the Service Interphone System
-Permits communication between the flight deck and the exterior maintenance jacks (excluding the external power panel)
-Requires the use of the CAB (transmission key and reception knob) controls on the ACP
What is the purpose of the Radio Management Panels (RMPs)
Used to select and tune all communication radios, SELCAL and standby navigational radios
What is the purpose of the Audio Control Panels (ACPs)
-Selection of radios and inter phone system for transmission and reception
-Control of reception volume
-Transmission of the public address system
-Filtering of Morse code signals from NAVAID reception
Function of each position of the INT/RAD switch
INT- Allows hands free (hot mic) transmission of the flight interphone system through a headset boom or oxygen mask inter phone.
Neutral- Requires the use of a sidestick trigger for transmission
RAD (spring loaded)- allows transmission for the selected transmission key
Recall the function of the AUDIO SWITCHING selector
-Permits selection of ACP 3 by either pilot in the even their respective ACP has failed
-When CAPT 3 of F/O3 has been selected, “AUDIO 3 XFRD” appears on the memo section of the E/WD
NOTE Use of ACP 3 does not affect either RMPs operation
Indications when receiving a transmission from SELCAL
CALL flashes in amber within the respective communication radio transmission keys (VHF 1/2/3 or HF 1/2
Buzzer sounds on flight deck
NOTE pressing RESET key on the ACP will extinguish a flashing CALL MECH or ATT light
Indications when receiving a transmission from Mechanic ground call from the external power panel
MECH flashes in amber within the INT transmission keys
buzzer sounds on the flight deck
Light goes off after 30 seconds if not reset
NOTE pressing RESET key on the ACP will extinguish a flashing CALL MECH or ATT light
Indications when receiving a transmission from Cabin Crew
ATT flashed in amber within the CAB transmission keys
Buzzer sounds in the flight deck
Light goes off after 60 seconds if it is not reset
NOTE pressing RESET key on the ACP will extinguish a flashing CALL MECH or ATT light
