For desaturation times lower than 70 minutes no no fly time is given In the Permanent Error mode and GAUGE mode the no fly time is 48 hours The Divers Alert Network DAN recommends the following on no fly times e A minimum surface interval of 12 hours would be required in order to be reasonably assured a diver will remain symptom free upon ascent to altitude in a commercial jetliner altitude up to 2 400 m 8 000 ft e Divers who plan to make daily multiple dives for several days or make dives that require decompression stops should take special precautions and wait for an extended interval beyond 12 hours before a flight Further the Undersea and Hyperbaric Medical Society UHMS suggests divers using standard air cylinders and exhibiting no symptoms of decompression illness wait 24 hours after their last dive to fly in an aircraft with cabin pressure up to 2 400 m 8 000 ft The only two exceptions to this recommendation are e Ifa diver has less than 2 hours total accumulated dive time in the last 48 hours a 12 hour surface interval before flying is recommended e Following any dive that required a decompression stop flying should be delayed for at least 24 hours and if possible for 48 hours e Suunto recommends that flying is avoided until all the DAN and UHMS guidelines as well as the dive computer s no fly conditions are satisfied 7 5 PLAN mode The PLAN mode includes a dive planner PLANnodec SUUNTO 7 5 1 Dive P
