•  If a diver had less than 2 hours total accumulated dive time in 

the last 48 hours, then a 12 hour surface interval before fl ying is 
recommended.

•  Following any dive that required a decompression stop, fl ying 

should be delayed for at least 24 hours, and if possible, for 48 
hours.

UHMS guidelines and the dive computer wait to fl y  conditions 
are satisfi ed.
