Free Dive; Repetitive Dive Planning; Flying After Diving - Suunto D4 User Manual

7.2.2. FREE Dive

Dive series is only for 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 D4 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 7.5.1. Dive Planning
mode (MEMPlan).

7.4. Flying after diving

In DIVE mode, the no-fly time is shown in the center window next to the airplane image.
In TIME mode, the airplane image is shown in the top left corner and the no-fly time
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 FREE 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:
