Free Dive; Repetitive Dive Planning; Flying After Diving - Suunto D4i User Manual

7.2.1. FREE Dive

Each dive series includes dives that have been performed during one day. The day's
dive numbering and latest dive information resets to 0 at midnight, and each day there
is a new series of dives that is recorded in the log book.
The dive is completed once you ascend beyond 0.5 m. A new dive will be registered
in the log book immediately you descend once again.

7.3. Repetitive dive planning

The Suunto D4i includes a dive planner that allows you to review the no-decompression
limits on a subsequent dive, taking the residual nitrogen loading of previous dives into
consideration. The DIVE PLANNING mode is explained in Section 7.5. DIVE PLAN-
NING 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 is displayed on the bottom row. 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 (if the dive has exceeded 10 minutes),
the no-fly time is 48 hours.
The Divers Alert Network (DAN) recommends the following on no-fly times:
