Dive Planner The dive planner facilitates the calculation of decompression profiles for simple dives Two different modes are available here Mode Description In the surface mode the user is able to plan a dive on the Surface mode basis of the parameters entered The current CNS load is taken into account during the calculation In dive mode the decompression profile is calculated Dive mode based on the current situation When calculating the decompression profile all gases input and the defined low and high gradient factors are taken into account Additionally the profile for the respective active circuit CC or OC is generated The dive planner is only intended for planning simple dives Multi level dives are therefore not supported Furthermore the following assumptions are applied to the calculation When calculating the decompression profile all gases input and the defined low and high gradient factors are taken into account Additionally the profile for the respective active circuit CC or OC is generated The dive planner is only intended for planning simple dives Multi level dives are therefore not supported Furthermore the following assumptions are applied to the calculation e The speed of descent and ascent is 10m per minute e In OC mode the gas with the highest PPO2 below 1 61 is used for a gas change e In CC mode the gas with the highest PPO2 below 1 05 is used for a gas change diluent

GF99 The current supersaturation gradient is then displayed as a percentage for a pure BUhImann 99 99 profile The number is calculated with reference to the current ambient pressure and M value It would appear conceivable that the figure is the current gradient tactor although this is not the case because this is calculated otherwise The current GF generates a stop rounded to the nearest 3 metres A GF of 40 reflects a stop at the next 4 5 metres The computer rounds the value up and displays a stop in the next 6 metres The GF form a line from the start of decompression star ted at the deepest stop and going right to the surface The gradient used for the stops is based on this line When ascending per BUhImann the decompression depth is reached if the ambient pressure of the next highest deco stage does not undercut the maximum ambient pressure tolerated by all relevant tissues The GF99 value displayed can be used for various purposes For example in order to carry out an aggressive ascent which still runs constantly per a reasonable format If a diver loses a large proportion of his brea thing gas and is required to ascend rapidly then he is able to ascend until a GF99 value of 90 Is displayed If in doing so an intended deco stop is missed out then a Missed Deco warning is displayed and must be confirmed It is then necessary to wait until this reduces to 80 and then ascend once again until 90 is displayed once
