PDPS (Pre Dive Planning Sequence)
The PDPS displays Depths and allowable No Deco Dive Times
(up to 999 minutes), NDLs (nitrogen based limits) if nitrogen is in
control or OTLs (oxygen based limits) if O2 is in control.
It will sequence through PDPS screens displaying Depths from 30
to 190 FT (9 to 57 M) with Plan times* based upon the previ-
ous dive profiles in a series of repetitive dives and taking into
account descent and ascent rates of 60 FPM (18 MPM).
*If less then 1 minute time is available, dashes will be displayed for time, and
Depth values will flash.
