7. Above MOD for 100%, missed switch: now TEC-3 gives the same decompression prognosis as TEC-
1. TEC-4 gives the same decompression prognosis as TEC-2.
8. Again below the MOD for 100%: TEC-3 and TEC-4 again show credit for the presence of the 100%
mix in their calculations
9. Above MOD for 100%, switch carried out: TEC-3 and TEC-4 show the tank pressure in the 100%
tank. The RBT agrees. TEC-2 is not receiving anymore signals from the 50% tank and shows “- - -“.
However, the slow ascent and delayed switch to 100% has caused the decompression prognosis to be
shorter on TEC-2 than TEC-3.
