6.1.6. Decompression dives
When your NO DEC TIME becomes zero, your dive becomes a decompression dive
so you must perform one or more decompression stops on your way to the surface.
The NO DEC TIME on your displaywill be replacedby an ASC TIME, and a CEILING
notation will appear.An upwardpointing arrow willalso promptyou tostart yourascent.
If you exceed the no-decompression limits on a dive, the dive computer will provide
the decompression information required for ascent. After this, the instrument will
continue to provide subsequent interval and repetitive dive information.
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 to ascend to the ceiling at an ascent rate of 10 m per minute/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)
