Fly/Desat; Plan - Aqua Lung i450T Owner's Manual

FLY/DESAT

The FLY/DESAT screen displays the Time to Fly and the DESAT (desaturation) countdown. The Time to Fly
countdown shall begin counting from 23:50 to 0:00 (hr:min), 10 minutes after surfacing from a dive. The DESAT
counter shall provide calculated time for Tissue Desaturation at sea level taking into consideration the CF (Con-
servative Factor) if it was set on. It shall begin counting down 10 minutes after surfacing from DIVE or FREE dives
counting down from a maximum of 23 to 10 (hr only), then 9:59 to 0:00 (hr:min). When the DESAT countdown
reaches 0:00 (hr:min), which will generally occur prior to the FLY countdown reaching 0:00 (hr:min), it will remain
on the display as 0:00 until the Fly count down reaches 0:00.

PLAN

This mode calculates dive depth and time limits. To do so, it accounts for any residual nitrogen, oxygen, surface
intervals, the programmed gas mix, and PO
are displayed, depending on whether nitrogen or oxygen levels will be the limiting factor. The time limit will display
as 1-99 minutes, all times greater than 99 display as 99.
NOTE: Depths exceeding the MOD (Maximum Operating Depth), if nitrox, or that have less than 1 min-
ute allowed dive time will not be displayed.
