The ascent time (ASC TIME) is the minimum amount of time needed to reach the
surface in a decompression dive. It includes:
•
time needed to ascend to the ceiling at an ascent rate of 10 m/min [33
ft/min] plus
•
time needed at the ceiling. The ceiling is the shallowest depth where
decompression could be made plus
•
time needed at the Mandatory Safety Stop (if any) plus
•
3 minute Recommended Safety Stop plus
•
time needed to reach the surface after the ceiling and safety stops have
been completed.
Your ascent time may increase if you:
- ascend slower than 10 m/min [33 ft/min] or
- make your decompression stop deeper than at the ceiling.
These factors will also increase the amount of air required to reach the surface.
