Boeing 737 Cold and dark startup noises
 

This video on youtube is great and it’s helping me customise my sounds to various switches and logic operation. Ie when i switch the BATT on, a hum noise starts just like this video...

I have my own replica 737 cockpit and tuning the sounds but just need help with what sounds should be heard and where they come from.


So in that video the pilot switches on the BATT for DC power - A hum noise can be heard and where does this come from?

When he puts AC power on the busses you can hear the Recirculation fans startup. Or is it the fans? Or is this the noise from electrical bay E&E bay?

Eh? Are you having a laugh?

Eh? No i’m not.

You can hear the tappets rattling away until the oil gets circulated to them too.

The guy likes flight simming, Would it really hurt that much to offer some useful information?

Got a pilot from Jet2 to send me a video of him cycling the Recirculation fans etc.

But I couldn’t make out the recirculation fans noise. Can you hear the fans noise and is it loud compared to the air cond packs when on?

Here is my part of my cockpit. its ready to be fitted into the shell very soon. As you can see the detail is amazing and i have spent a fair bit of money. I have also got two 737-600 IPECO seats on J rails and many more items like linked rudder pedals, linked under floor yoke.

So if you dont have an air source during startup and only ground power, after putting the GRD PWR on the busses will you hear the recirc fans without the packs on and supplying air?

So regardless of an air source, the recirculation fans will run and blow air? You’ll also have the equip cooling fans also during the preliminary flightdeck procedure!

That would be great if you could take note next time :)

My cockpit is in my own home. Even got Telex750 airman headsets hooked up as a intercom system.

Ok thankyou for your response, much appreciated

Oh wow pretty cool!
