8. GLOSSARY
Altitude dive A dive made at an elevation above 700 m [2300 ft] above sea-level.
Air time The amount of dive time remaining, based on a calculation of cylinder
pressure and present air consumption.
Ascent rate The speed at which the diver ascends toward the surface.
ASC RATE Abbreviation for ascent rate.
Ascent time The minimum amount of time needed to reach the surface in a
decompression dive.
ASC TIME Abbreviation for ascent time.
Ceiling On a decompression dive the shallowest depth to which a diver may ascend
based on computer nitrogen load.
Ceiling zone On a decompression dive the zone between the ceiling and the ceiling
plus 1.8 m [6 ft]. This depth range is displayed with the two arrows pointing toward each
other (the "hour glass" icon).
Compartment See "Tissue group".
DCS Abbreviation for decompression sickness.
Decompression Time spent at a decompression stop or range before surfacing, to
allow absorbed nitrogen to escape naturally from tissues.
Decompression sickness Any of a variety of maladies resulting either primarily or
secondarily from the formation of nitrogen bubbles in tissues or body fluids, as a result
of inadequately controlled decompression. Commonly called "bends" or "DCS".
Dive series A group of repetitive dives between which the FAVOR AIR indicates
some nitrogen loading is present. When nitrogen loading reaches zero the FAVOR AIR
deactivates.
Dive time Elapsed time between leaving the surface to descend, and returning to the
surface at the end of a dive.
Half-time After a change in ambient pressure, the amount of time required for the
partial pressure of nitrogen in a theoretical compartment to go half-way from its previous
value to saturation at the new ambient pressure.
HP Abbreviation for high pressure (= cylinder pressure).
