KNOWING WHEN TO FLY
Due to the present lack of a complete data set derived from actual human
testing, there are different recommendations cited by various scientific organiza-
tions for the amount of time a diver should wait before flying after diving. The
DataPlus follows one of the more conservative of these, cited by Divers Alert
Network (DAN); that divers wait at least 12 hours before flying in pressurized
commercial aircraft, and at least 24, or more, hours if your profiles included
repetitive multi-day or decompression dives. More about flying after diving and
DAN's guidelines is presented on page 76 in the Reference section.
The DataPlus tracks how much surface time has elapsed since you surfaced from
your latest dive. The Time to Fly Mode begins a 24 hour countdown that
starts 10 seconds after a dive (Fig. 18). During the first 12 hours, the countdown
appears for several seconds after the Surface Mode during the Surface Sequence.
During the second 12 hours of the countdown, only the word 'FLY' and the
counter will be displayed (Fig. 19). During this second period, depressing the
control button will reactivate the DataPlus, replacing the Time to Fly countdown
with the Surface Display and scrolling Surface Sequence.
WARNING: Battery removal and replacement will clear the Time
to Fly countdown.
