Rather than requiring you to make stops at fixed depths, the dive computer lets you
decompress within a range of depths (continuous decompression).
The ascent time (ASC TIME) is the minimum amount of time needed to reach the
surface in a decompression dive. It includes:
•
the time needed at the deep stop
•
the time needed to ascend to the ceiling at an ascent rate of 10 m/33 ft per minute.
The ceiling is the shallowest depth to which you should ascend.
•
the time needed at the ceiling
•
the time needed at the Mandatory Safety Stop (if any)
•
the time needed to reach the surface after the ceiling and Safety Stops have been
completed
WARNING
YOUR ACTUAL ASCENT TIME MAY BE LONGER THAN DIS-
PLAYED BY THE INSTRUMENT! The ascent time will increase
if you:
•
remain at depth
•
ascend slower than 10 m/33 ft per minute or
•
make your decompression stop deeper than at the ceiling
These factors will also increase the amount of air required to
reach the surface.
Ceiling, ceiling zone, floor and decompression range
When in decompression, it is important that you understand the meaning of ceiling,
floor, and decompression range.
