1 meter per 20 seconds!?

applesthecat · 05-02-09, 11:49 PM

What is a normal descent/ascent rate for a type vii sub? I find that my sub goes up or down by about 1 meter every 20 seconds and perhaps only a little faster with blow tanks or crash dive.

Is this normal? The sub had a nose down attitude of only about 5 degree when descending. Also, is there a way to manually manipulate the dive planes, like on silent hunter I to dive faster?

I also found I could not rise with my engines off. Shouldn't blowing ballast rise the sub regardless of forward speed? Don't subs rise by positive buoyancy?

I had no damage to my dive planes.

Thanks

I can only say that it's way too slow

. When crashdiving it should probably be more like 1m/1s.

It's not possible to manually manipulate the dive planes.

Yes, you should be able to rise without engines... and blowing ballast should get you to the surface fast.

I find blowing just half the tanks in an emergency surface is that fast,the sudden blast of oxygen at the surface into the boat almost knocks the men out

You have to use some speed to make your sub respond to dive-plane inputs. No speed = no pressure on the planes = no changes in depth.

The way the game is coded means speed is the key I'm afraid....the faster the speed, the faster the descent.

Hypoxia is a pathological condition in which the body as a whole (generalized hypoxia) or a region of the body (tissue hypoxia) is deprived of adequate oxygen supply. Variations in arterial oxygen concentrations can be part of the normal physiology, for example, during strenuous physical exercise. A mismatch between oxygen supply and its demand at the cellular level may result in a hypoxic condition. Hypoxia in which there is complete deprivation of oxygen supply is referred to as anoxia. When there is flatulence in a sub when under pressure, the men will experience euphoria a condition that is overcome by flatulence with particulate which is to be avoided. A rush of salty clean AIR (not oxygen)will cause the inner ear to pop causing a distress on the knee joints and a relaxed bowel movement on those seated. This was a known issue and was never treated in the training manuals. Notice all the men stand up when opening the hatch (in all movies).
