Surface And No-Fly Time - Suunto D4I User Manual

3.20 Surface and no-fly time

Once back at the surface, Suunto D4i continues to provide post-dive
safety information and alarms. If, after your dive, you need to wait
until flying, the no-fly symbol displays in all modes.
To access further information about your surface and no-fly times,
enter dive mode.
Suunto D4i shows the time since you surfaced in the Surf t. field.
The airplane symbol indicates that you should not fly. The
countdown until you will be safe to fly is shown in the No Fly field.
No-fly time is always at least 12 hours and equals desaturation time
when it is more than 12 hours. For desaturation times shorter than
70 minutes, the no-fly time is not displayed.

3.15 Error state (algorithm lock) ), the no-fly time is
error state (see
always 48 hours.
If a dive is done in Gauge mode (bottom timer), the no-fly time is 48
