Step 4 – ACP (Audio Control Panel)
- Identify each knob:
- VHF 1 / VHF 2 / HF 1 / HF 2 – Rx volume & selection.
- INT – Interphone volume.
- CAB – Cabin address.
- MECH – Mechanical call.
- Transmit key (push and hold to speak on selected radio).
A. Audio Management System (AMS)
The AMS is the core of the communications system. It allows the crew to select and regulate audio signals. Identify each knob:
-
Components:
- Audio Control Panels (ACP): Located on the pedestal (one for Captain, First Officer, and Third Occupant). Used to select communication radios and interphones.
- Audio Management Units (AMU): Located in the avionics bay. They process audio signals.
- RMP Tuning: Communication frequencies are tuned via the Radio Management Panels (RMPs).
-
Operation:
- Transmission: Pressing the PTT (Push-To-Talk) switch on the sidestick or the ACP (INT/RAD switch) activates transmission.
- Reception: Controlled via the VOL knobs on the ACP.
- Call Signs: Entered via the MCDU (Multifunction Control Display Unit) for ATC data link.
Step 7 – Interactive Scenarios
- Typical CBT quiz:
- “VHF 1 fails. How do you transmit on VHF 2?”
→ Select VHF 2 on ACP transmitter selector.
- “How to listen to both VHF 1 and VHF 2?”
→ Pull both VHF 1 and VHF 2 knobs on ACP (volume set).
