Dive planner
VI Dive planner
XP AIR has a dive planner which allows the planning of no-stop dives as well as decompression dives
with freely determinable surface intervals.
Basis of the planning:
• selected fraction of oxygen and MOD
• selected microbubble level
• water temperature of the most recent dive
• altitude range (if any)
• status of saturation at the time the dive planner is selected
• assuming a normal workload of the diver and observance of the prescribed ascent rates
!
WARNING
If two or more divers using computers are planning a dive, planning for all divers has to be based
on the dive computer showing the shortest no-stop times. Failure to do this may lead to serious
injury or death from decompression sickness.
1 Planning a no-stop dive
With the contacts B and
+ or B and – you can
select the dive planner
at the surface. (The
dive planner cannot be
selected in gauge mode)
NO
The microbubble
warning and its duration
are displayed if XP AIR
detects an increased risk
due to the accumulation of microbubbles.
Enter the dive planner with B and E.
The input window for the time interval is
displayed if there was a remaining desaturation
(DESAT) before the Dive Planner has been
selected. This surface interval between now
and the beginning of the dive can be changed
with the contacts B and + or B and – in steps
of 15 minutes.
NO
If a microbubble warning (no dive) and its
duration has been displayed, XP AIR proposes
this time – rounded up to the next 15 minutes – as surface interval. If the
proposed interval is shortened, the microbubble warning appears.
With B and E you confirm the displayed interval (if applicable), then XP AIR
starts scrolling the no-stop times. The no-stop times are displayed in 3
metre increments (10 ft) and are displayed for every increment for about 2
seconds. The process starts at 3 metres (10 ft).
If a microbubble level has been selected (L1-L5), the MB no-stop time
is shown.
No-stop times will be displayed as long as the selected maximum
operating depth (MOD) is not exceeded.
NO
On page 25 you will find further information and safety considerations
regarding the microbubble warning.
