Where is the main induction valve?

To quote the guide:

The ventilation system is controlled from the Misc. Systems Control Panel in the control room.

.....

The ventilation system can be purged and filled with fresh air by opening the main induction valve while the submarine is surfaced. DO NOT open the main induction valve while the submarine is submerged! This will flood the ventilation system and rapidly fill the submarine with water.

I can't find this valve. How do I open it, or is it taken care of automatically?

Welcome aboard Subway Commander, it's always good to see new faces round these here parts!

When you are in the misc. system control panel, press 'p' to start/stop purging the ventilation system!

Welcome to SubSim SubwayCommander.

I had a bit of trouble logging in again after my previous SubwayCommander account got banned, weird. Thanks to the admin for helping!

Pressing P did the trick indeed, thanks for the help guys!

Actually - in real life - the main induction valve has a couple if electrodes on the masthead - when sea water completes the circuit - the valve slams shut via high pressure air... When that happens - you can hear it - boom... Welcome aboard...

Very interesting, thanks Scott! I figured there would be some kind of safety system but wasn't sure what it was or how it was triggered. I'll add that to the sim straight away.

Hi Geoff,

Happy to help... Yeah - normally there were actually two bangs that could be heard throughout the boat and probably for miles... One for the close and another when it opened again - there was a great deal of force involved... Boom - - - Boom... When I was in - the USS Houston (rep as bad luck boat) had the induction valve closure mechanism fail - or - something wasn't lined up properly - they took massive amounts of sea water down the induction mast and the ventilation system distributed it nicely around the boat - they were pulling wet stuff off for weeks... Same boat that snagged a tow line between a tug and barge with their sail - immediately sinking the tug and killing some of its crew - during the filming of Hunt for Red October...

It's been a while but I was actually qualified all the real operational watch stations (ETOW, QMOW, STOW, FTOW, and COW)... If any questions ever come up - please feel free to ping me...

Regards,
Scott ET1/SS

Hmm - for those interested - the Houston was MUCH worse than I even knew...

This reads like a horror story:

TheGeoff, please make sure the main induction valve can still fail, so we can have some hilarious endings to our games when we fail to notice it's broken.

[TheGeoff]

Done -the main induction valve will now shut automatically when water reaches the top of the sail to prevent flooding, but it is occasionally possible for the detection mechanism to fail. I've also added 'boom' sound effects for opening and closing the valve, hopefully they sound close to the real thing.

Hmm - for those interested - the Houston was MUCH worse than I even knew...

Terrifying stuff... that's one unlucky ship. No wonder it ended up with such a reputation.

Yea, I was a plank-owner on the Jacksonville and I think they were in the running with us for the unluckiest LA class. I was the lookout for our first collision and I think she is up to 4 or 5 of them now. Amazed she is still in the fleet. Not for long though I am sure.
