out of curosity, who was your instructor?
the OPV is on the bottom of the lung so you can flush water out of it that may get in via the loop falling out of your mouth (or getting kicked out,which is more likely). were you not taught that skill?
if you have to ascend off the loop, you occasionally roll right so it vents, just like a normal ascent.
a pull dump high is an invitation for all sorts of crap to get stuck in it, like cave silt, rust flakes etc.
Thanks for the input Ron...obviously all aspects of flood removal and bailoff are covered within the Meg training....I was however under the impression that this was about what improvements a user would like to make to his unit. In my case, maybe wrongly, I think that the provision of a pull dump, in particular in a high task load scenario on the ascent,may be a good thing. Remember, with the bov in situ, you have in effect a closed loop and are threrfor relying on the opv to vent gas on the way up.
Dont APD have a pulldump on the lung for just such a thing?
