Re: [PSUBS-MAILIST] Ambient Pressure (No Subject)

I would like to make a comment on your dive plan.  I think that a sub should 
never get into a negative buoyancy state.  When it starts to descend it gains 
speed.  To compensate, you have to become quit a bit positive buoyant in 
order to stop the decent.  Then you fight the accent.  Set your buoyancy a 
slight bit positive and fly the sub with your motors.  It is amazing how fast 
you get overwhelmed when trying to compensate with valving.
