3. Diving with Galileo2000m/6600ft (switch point at815mbar);- class 2: from approximately2000m/6600ft to approximately3000m/10000ft (switch point at725mbar);- class 3: from approximately3000m/10000ft to approximately4000m/13300ft (switch point at610mbar);- class 4: above approximately4000m/13300ft. In this altitude classGalileo functions in gauge mode only(automatic switch from computer mode).The altitude classes are defi ned in terms ofapproximate elevations because the effectof weather conditions can make the switchpoint pressure occur at different levels.No deco datagauge modeSwitch point at 610 mbar / 8,85 psiSwitch point at 725 mbar / 10,51 psiSwitch point at 815 mbar / 11,82 psiSwitch point at 905 mbar / 13,82 psi4000 m13120ft3000 m9840ft2000 m6560ft1000 m3280ftGalileo deals with altitude automatically: itmonitors the atmospheric pressure every60 seconds, even when it is turned off, andif it detects a suffi cient drop in pressure, itdoes the following:- it switches on (if it was off);- it indicates the new altitude range bymeans of black segments inside thestylized mountain and, if applicable, theprohibited altitude range;- it indicates the desaturation time, whichin this case is an adaptation time tothe new ambient pressure. If a diveis started during this adaptation time,Galileo considers it a repetitive dive,since the body has residual nitrogen.0 m3.6.1 Prohibited altitudeGoing to altitude, as much as fl ying afterdiving, exposes your body to a reducedambient pressure. In a way similar to theno-fl y time, Galileo advises you whichaltitude classes are safe to reach after adive and which aren’t. If you have to driveover a mountain pass to return home aftera dive, it can be quite important to have thisinformation.The prohibited altitude classes aredisplayed by grey segments inside thestylized mountain. This can be combinedwith black segments indicating currentaltitude. In the example above, the diver ispresently at altitude class 2 and should notreach altitudes of class 4.Galileo has an altitude alarm: if you were toreach an altitude that according to Galileois incompatible with your current residualnitrogen levels, it will warn you with analtitude alarm (see section 1.4 for moreinformation).3.6.2 Decompression divesin mountain lakesIn order to assure optimal decompressioneven at higher altitudes, the 3m/10ftdecompression stage is divided into a4m/13ft stage and a 2m/7ft stage in altituderanges 1, 2 and 3.If atmospheric pressure is below 610mbar(altitude higher than 4000m/13300ft), nodecompression calculation is carried outby Galileo (automatic gauge mode). Inaddition, the dive planner is not available inthis altitude class.60
