Hi,

as i am now diving with a OSTC2 and OSTC4 (both on newest firmware; both used with ZH-L16+GF and same gradient factors) a im wondering, how the OSTC4 is calculating the no fly waiting time. In the OSTC2 set to to "flying".

On the OSTC4 i found no option to change this. And in the manual no hint (or i missed it) how it is calculated or can be changed to different parameters...

During the last dive the OSTC2 and 4 showed the same deco times. But the next morning, the OSTC2 showed no waiting time, whereas the OSTC4 showed 11hours...

Hi,

the OSTC2 really calculates a no-fly-time, it is done in the same way as a deco stop calculation, with the only change that the target depth is not surface pressue but an aircraft cabin altitude pressure. The OSTC4 does the traditional 24 hours count-down.
