SUUNTO HELO2 - Manual (Page 76)

7.3. Repetitive dive planning
The Suunto HelO2 includes a dive planner that allows you to review the no-decom-
pression limits on a subsequent dive, taking the residual nitrogen loading of previous
dives into consideration. The dive plan mode is not meant for technical dive planning
which the Suunto Dive Planner PC software is meant for. However, the dive plan mode
can be used to plan short recreational dives.
The PC software takes the residual inert gas of the previous dives into consideration
when the dive profile is downloaded from the dive computer. It is also possible to check
how the planned air consumption corresponded to the actual air consumption. The
DIVE PLANNING mode is explained in Section 7.5.1. DIVE PLANNING mode (PLAN
NoDec).
7.4. Flying after diving
In the DIVE mode, the no-fly time is displayed in the center window next to the airplane
image. In the TIME mode, the airplane image is shown in the top left corner.The no-
fly time and the surface time are shown in the TIME mode as well. Flying or traveling
to a higher altitude should be avoided at any time when the computer is counting down
the no-fly time.
The no-fly time is always at least 12 hours, or equivalent to the so-called desaturation
time (if longer than 12 hours). For desaturation times lower than 70 minutes, no no-
fly time is given.
In the Permanent Error mode and GAUGE mode, the no-fly time is 48 hours.
The Divers Alert Network (DAN) recommends the following on no-fly times:
