Hi, this is a question about the most specific things regarding communications in an aircraft. What specifically does a pilot do to communicate with the VHF or HF frequency? That is, how do they select on which radio they want to talk through, and how do they talk over the frequency? I was also wondering how the Ground call on the SELCAL panel works as well. I appreciate any information you can provide me, I find a strong interest in these sort of specific details of flying!
PS: How do you switch between "speaker-phone" and headset transmissions and adjust the volume?

The pilot can select which radio he wants to transmit/receive through the ACP (Audio Control Panel). You can transmit through 3 different mode:
-Pressing a button on the ACP (PTT).
-Using an hand mike (not used in all planes)
-Pressing the button on the Yoke
I was also wondering how the Ground call on the SELCAL panel works as well
If you press the GROUND CALL switch a horn sound to alert ground personnel that pilots want to talk to them
The GROUND CALL light means pilots are called by ground personnel.
Anyone know what is the difference on the ACP between BOOM and MASK?

Thanks everyone for your replys. So you select the radios through the Audio Control Panel (that's on the pedestal right?) and you transmit by pressing the PTT, or the button on the yoke. Where is that button on the yoke? I've seen the trims and A/P disconnect, but not the transmit button. I was also still wondering about the speakers vs. headset. Thanks in advance
PS: that horn thing is actually pretty funny, I think I've been asked that question many times: Do aircraft beep at other aircraft? It's like the "do aircraft have keys?" question. My friends will laugh when I tell them you guys have honked at goats!

Do they need to use the PTT when they are talking to the ground? I always had the impression that it it was more like a telephone where you could both just talk. Also, what is the cabin interphone like, a telephone type of system, or again, with a PTT? Could one of you pilots like Rick767 post a short item by item list that would be the normal steps a pilot would do during ground communications and/or cabin communications? That would be great.

AJ & CX Flyboy...
At least you don't fly to PKU/WIBB Pekanbaru...
"Tower, Indonesia172, I think we'll delay take off and hold on the threshold for a few minutes... please notify traffic"
"172, what's the problem?"
"There's a HUGE lizard taking a stroll crossing the runway in front of us!"
Hmm, a 2.5m long lizard! Fun !
Or CGK/WIII Jakarta Soekarno-Hatta...
"Indonesia 174, be advised we recommend you take 07R. 07L approach has MANY kites. SQ hit a few earlier..."
When losing situational awareness, pray Cumulus Granitus isn't nearby !

The cabin interphone system and the the interphone to the engineer (I think) are both like a telephone. You can talk at the same time.
We chat to the ground engineer normally just before we push back. A typical conversation starts when I see on the door synoptic that all the doors are closed (Including various access hatches and cargo doors).
Pilot Flying (PF): Cockpit to ground.
Engineer (ENG): Go ahead.
PF: Confirm all doors checked closed and locked?
ENG: Confirm, all doors checked closed and locked.
PF: Are we cleared to pressurise?
ENG: Afirm, clear to pressurise.

After pushback.....By this time, the start should be complete and the AFTER START checklist complete
ENG: Ground to cockpit, pushback complete, set park brake.
PF: Park brake set, start is complete you are cleared to disconnect.
ENG: Roger, pin removed, clearance on the right hand side, bye bye.
PF: Bye bye.
Sometimes we need to start one engine on the bay with ground air etc..and that will involve more procedures.
As for calling the cabin, none of our procedures really specify that we have to call them using the cabin interphone expect some emergencies, and there is no specific wording we have to use, so that is normally very casual speak.
Sorry I had to split this message up. My computer cannot seem to do long replies on this forum. Not sure why, it just times out.
