If you look at the call system section (5.10.13), it says under attendant call that it sounds a "two-tone chime" in the cabin. In the NGX it, from the cockpit, I hear only a one-tone. Obviously - if this is an error - it's a trivial one at best. I'm just curious if the cabin hears a two-tone chime but the flight deck only hears one.

Yes, I was wondering about this as well. Is "two-tone" no longer the standard? Travis McKinney

Are you using the attendant call button or the "chime" switch (originally a No Smoking switch)? Either way, I'm pretty sure the FA call would not be audible from the flight deck.

I could hear it in the cockpit of an A320 with closed doors (seatbelt on during descend), so I think, you can hear it in the 737 as well ;)

We are talking about the "Attend" button, right? Yeah I hear one tone, which apparently isn't correct. Or is it?

Adding on to this If I may, I have yet to hear a seatbelt sign sound in a FSX plane that sounds just like the real thing, the seatbelt sign in the 737NGX has only one tone when it should have two as well as the attend button.

They're not all the same, ya know

As I understand the original question, the matter is whether the "attendant" button (which we definitely can hear) should actually be one tone or "two-tone," as it is in most 737NGs in the U.S. anyway. As of now, we hear one beautiful tone, but usually, so far as I have experienced, the 737NG has a "two-tone" attendant call in actual operations--this is further specified in the manual, as Ruben 1123 mentioned earlier.

Yes, the attendant call. tj, yes and thanks.

Plus it is also very very low - the sound needs to be pumped up a bit - and for all you people who tell me the chime is not for the cockpit - in the real plane you can still here it very loud in the cockpit - and on top of that the ground crew call sound is also very low and that you are def not supposed to hear in the cabin

Uh, I hear two tones. Faint, but it's there. Trevor

Trevor, I'm not so sure that you hear a two-tone chime. Please confirm (and make sure it's not in your head )

I'll confirm when I get home, but I've flown several flights now, and I use the chime all of the time. Besides, there are plenty of other weird things in my head. No room for auditory hallucinations. Trevor

Thanks; do tell.

All 737NG's and Classics I've been on, have had a single tone, but way louder, chime for the fasten seatbelt sign... (and I do fly quite a bit NG's with lots of different customer numbers ;-) )
