filling tanks to negative to go deeper yes.
with motors to go faster.
like when the say Blow negative.
choices are negative positive and neutral.
GWX has a minor positive bouancy pulling you up
slowly to about two metres above ordered depth

Not true.
First the tanks are flooded to negative or neutral bouyancy.
Second power is switched to electric motors.
Third the planes are pointed downward.
In answer to the original question, once neutral bouyancy is established all depth changes are done with the dive planes. The ballast levels recieve minor adjustments if needed.
When surfacing, all water is blown out of the tanks. There is no ballast when surfaced. |
Well I certainly dont intend to argue with your level of experience steve
I stand corrected and will be more detailed and carful next time.
