3. Diving with Galileoat L4 but decide not to carry out all therequired L4 stops, you can cascade downthrough L3, L2, L1 all the way to L0. Onlydecompression stops relating to L0 aremandatory and must be respected at alltimes, whereas the level stops calculatedby the MB levels are recommended but notmandatory. Section 3.5.5 describes how tocascade to a lower level.EnglishFor FULL lay-out, the underlying L0information is shown in the sequence rightafter the BUDDY tank pressure and beforethe CNS O 2. This is displayed instead ofthe MB level no-stop or decompressioninformation and remains there only for5 seconds, after which it is replaced againby the information relative to the active MBlevel.3.5.5 Level stop ignored/MB levelreducedIf a level stop is required and you ascend1.5m/5ft or more above it, Galileo willreduce your active MB level to the next onecompatible with the current depth. Whenthis happens, the new active MB level ispermanently displayed on the screen. It is nolonger possible to fi nish the dive with the MBlevel set at the beginning of the dive. Whenthe level stop depth is the same as the decostop depth, ascending 1.5m/5ft above it willcause Galileo to cascade down to L0.At the end of the dive, for fi ve minutes afterreaching the surface, the active (reduced)MB level is shown on the display. After fi veminutes Galileo changes to surface modeand switches back to the MB level set priorto the dive, but the reduced MB level isrecorded on the fi fth page of the logbook.3.6 Altitude and thedecompression algorithm NOTE:The nitrogen bar graph alwaysreferences the underlying L0 calculation.3.5.4 Cascading MB levelsWhen diving with an MB level, Galileocarries out all calculations relating to L0 andto all MB levels in between the currentlyactive one and L0. This gives the diver thefl exibility to start with a given MB level butto cascade down to a less conservativelevel during the dive: if you start the diveAtmospheric pressure is a function of altitudeand of weather conditions. This is an importantaspect to consider for diving, because theatmospheric pressure surrounding you hasan infl uence on ongassing and offgassingof nitrogen. Above a certain altitude, thedecompression algorithm has to change inorder to account for the effect of the changein atmospheric pressure.Galileo divides the possible altitude rangein 5 classes:- class 0 (not indicated on the computerdisplay): from sea level to approximately1000m/3300ft (switch point at905mbar);- class 1: from approximately1000m/3300ft to approximately59
