Clanging background noise in cockpit

sg_aviation

Hi,

I'm regularly noticing a clanging background noise while on the ground. It does not relate to aircraft movement, turning on any specific system or air flow.

In fact it sounds quite annyoing and I am unable to identify any rule when/where it occurs.

Any ideas?

This will be a tricky one to deduce without a video. A "clanging" noise suggests it could be the passenger boarding/deboarding audio, but it is difficult to say without a video.

Here you go:

The before flight the sound stops when closing doors, after landing it starts when reaching taxi speed.

Mine makes a crash bang sound right after the FO calls out "Go" before he says rotate, and then it happens again on landing while rolling off the runway i think, sounds like a big bang

@sg_aviation That's not something I can replicate on my end, but it possibly sounds like the audio you would hear if you taxied the aircraft on dirt or gravel, etc.

Do you perhaps have FS Realistic installed? As I believe certain settings have caused similar issues in other aircraft.

@Sergekoko That's not something we can replicate on our end, nor we have seen it reported. Do you perhaps have FS Realistic installed?

I dont, but i suspect it may be the scenery or something as well having that bump

No FS Realistic and no GSX installed, plus it relates to aircraft specific actions.

@Mark Here's more details about how to reproduce:

Departure

Load flight
Select "Turnaround" state from EFB
Sound appears
Set EXT AC to OFF or Close FWD PAX DOOR from EFB
Sound disappears
Set EXT AC to ON or Open FWD PAX DOOR from EFB
No sound appears!

Arrival

Land aircraft
Decelerate below 15 kt
Sound appears
Connect Ground Power & APU
Set EXT AC or APU to OFF
Sound disappears
Set EXT AC or APU to ON
No sound appears!

This indicates a bug, since I cannot imagine any situation where such sound could appear in line with the actions described. While the sound may be similar to ground roll rumbling, it can also be a clacing induced by air vent/flow or similar - in the end it's up to you to define the sound origin, since there is no other source like FS Realistic etc.
