A question about gauges
 

If you go to the station for blowing the main ballast tanks, there are a number of gauges facing you. The upper left and upper right appear to be calibrated for high pressure air, but I can see no indications on them which conform to my understanding of the operation of the MBT's/HP Air.

Would I be correct in thinking that whatever they indicate hasn't yet been incorporated in the game, or, if they are working, what precisely are they indicating?

welcome aboard!
 

I'm coming to suspect it's a measurement of the captain's intra-cranial vacuum pressure. If you watch it carefully, every time the pressure reduces, it happens immediately after he's been a clot!

Hi Fidd,
I think the 2 meters measure the air pressure inside the FWD and AFT MBTs.
On the surface, blowing the 2 MBTs will create a pressure of about 1 kg/cm² in each tank.
If you flood the tanks, the pressure is reduced to almost zero.

If you blow the tanks at a depth of 140 m, you'll see the pressure build up to about 2 kg/cm² and then reduce to 1 kg/cm² when the boat reaches the surface.

I think I read somewhere that the pressure had to be carefully monitored not to exceed a certain level. I noticed that after performing an emergency surface (blowing Main Ballasts) from a depth of 200 m, the compressor leaks all the way down to zero, at which point the diesel can't be started, nor can the compressor! If that's the case, what is the critical pressure not to exceed?
