Hi there,
asked before in https://forums.flightsimulator.com/t/a320nx-triple-click-after-external-power-on/333382 but still not sure why is it not there anymore. I remember it was at the beginning, dissapeared and then was available again.
Currently I cannot hear clicks. Are they non existent in NEO variant? I am asking cause I believe that this sound is a sign that you can continue with APU fire test after turning EXT power on (at least heard that from 320 Sim Pilot on YT).
Thank you for your answers.
If you are referring to the three ‘chirrups’ sounds in quick succession - that is confirmation that the FMGC’s have completed self-test and the Fly By Wire systems have come online and are capable.
You’ll hear them the after the test period of about 10-15 seconds when switching from Battery to EXT Power - or, if you go from Battery direct to APU - in the absence of EXT Power. They work the same on the NEO as they do on any of the other variants.
Last time I flew the latest FBW DEV version (in between HF1 and HF2 post SU5 I’m pretty sure I recall they were audible.
Thank you for your answer.
The problem is that these clicks are inaudible for me. I can’ t hear them even with having headphones on. Using lastest dev version installed one more time after last hotfix.
Going from battery to external power and all is ok with the aircraft but missing the sound.
Did you try aligning the IRS’s? - I think they can tank - and not sound off - if GPS PRIMARY LOST is in - indicated on the FMGC. Which can persist until you’re aligned.
Not strictly how it works real world - but give it a go and see.
Remember to listen out just after you get IRS alignment after however long you’ve set it to do so.
Yes I did. Tried to use different options from instant aligning to real but still sound is missing after alignment. Checked also on default livery.
No idea if it is only my case or is it missing already cause I remember it was available some time ago.
I’ve just this minute started up the FBW A320 (latest as of 1300 UTC 08/08/2021 development version) and the three clicks are indeed missing.
Thank you for confirmation so I know that is not my setup. Will wait for the fix till the team will be able to look into that
