Re: OSTC Sport - Gasbedarf

Hallo Jan, die Gasbedarfs-Berechnung und Warnung war ursprünglich nur für den CCR-Modus gedacht um zu warnen, wenn es für einen Bailout-Aufstieg anfängt knapp zu werden. Dazu sind dann die Fülldrücke (ggf. Abzüglich einer "eisernen Reserve") der einzelnen Gase einzugeben. Dann ist mir bei ...

Re: OSTC Sport - Gasbedarf

Am "Startgas" liegt es nicht und die AMV (SAC)-Raten gelten nicht für die jeweiligen Gase, sondern für die Phasen des TG: normal und in der Deko (genauer: auf einem Stop). Evt. liegt der Fehler darin dass du dem Startgas keine Wechseltiefe (MOD) gegeben hast. Das ist eine Schwäche in der a...

Re: Display problem with my OSTC Sport firmware 10.38

Hi Jean, the display problem will most likely go away with an updated firmware, because it is not a hardware problem but the software is just stuck in printing in reverse mode. Seems to be a bug in that old firmware. You do not need to install every single update. As you will be doing a big jump, yo...

Re: TTS bei deaktivierten Dekogasen, Bug?

Hi, i think that solution is warm, but not hot. Try out this: gas1: Air, 56m, first gas2: Nx50, 21m, disabled gas3: O2, 6m, deco gas4 & 5 disabled Start the simulator, descent to 30 m and then give the dive some +5' such that the first stop goes down to 12 to 15 meters. Now ascent to 20 meters a...

Re: Gradient Factors

I really had to look into the code to give a prceise answer. Here it is: 1) The GF-low reference depth is set to the depth of the deepest deco stop found during the whole dive. 2) When two plan are calculated (fTTS or OC bailout), each plan has its own GF-low reference depth. 3) When the GF factors ...

Hallo Enrico, die aktuelle 2er Software berechnet die TTS parallel mit der Berechnung des Deko-Plans. Beide basieren auf den verfügbaren aktiven Deko-Gasen sowie dem aktuellen Gas. Die Berechnung beginnt mit dem aktuellen Gas und schaltet dann entlang des Aufstiegs auf eines der Deko-Gase um, wenn d...

Re: Gradient Factors

Hi Yves, "Variable Speed" is no longer in the current hwOS firmware. As of now, the OSTC always calculates the ascent with 10m/min, as defined within the Bühlmann model. This parameter or better to say speed limitation is important, as can be seen when looking at the half-times of the fast...

Re: OSTC+ Tech simulations

Hi Yves, that's probably one of the longest posts we ever had! I'll try to catch the remaining open items only: Ascents are calculated with 10m/min, because that's the design of the Bühlmann model. Sure the slower the better, so when you do 6m/min or even just 1m/min up from the last stop you'll be ...

Re: OSTC+ Tech simulations

Hi, you are good on track and actually already deep into the details of the deco calculation algorithm. NDL x' is the "count-down" of remaining NDL time. With x = 0 you are riding on the edge of the NDL (in German language we call that "Nullzeitschrammeln"). It is correct that th...

Re: Gradient Factors

The supersaturation bars show the sum of N2+ He, as this is what goes into the deco calculation and what the GF low, GF high and m-line is rated against. The turquoise bar actually just looks like a bar when there is no supersaturation at all, indeed it the 16 horizontal lines that show the relative...

Re: Batterie size issue

For the 1.5 V battery, there is a combination of power consumption calculation and battery voltage levels. The lower one determines the resulting percentage that is shown. Please note that 1.5V cells in the Plus model are intended for emergency use only, as this model internally runs on 3 Volt. So a...

Re: Gradient Factors

Unfortunately other brands than Shearwater do not match that good (to either OSTC or Shearwater), as these tend to add internal safety factors that result in more deco obligation than a calculation with plain & strict Bühlmann and E.Baker GFs would yield.
