No GA (saved) Hobbs Time, based on Oil Pressure switch?

Is there a true GA Hobs time . ie Hours that the Low Oil pressure is above a
minimum value, indicating the engine is running, There appears to be two Times
being kept and State saved. (1) Tach Time - Hours, function of accumulated RPM
(2) Flight Time (counting when RMP .> RPM Min, and Speed > speed min) There is
no true Hobbs Time, ie Oil pressure > Oil pressure Min. With the lack of True
GA Hobbs time, (as defined above), this may explain what the C172 Classic, has
BOTH its Tach Hours, and its Hobbs Hours, displaying the Tach Time ?? I would
suggest that all 3 times should be being kept track of, and state saved for
each plane in their State saved file. ( including Tach Time for each engine)
Note: Flight Time cannot be used to be correct Hobbs time, since the speed ,
even when set to Zero, still will not allow the Time to be counted, Unless
speed is GREATER than Zero. Setting a negative Min speed does not work …( Non
signed Integer arithmetic ?) Even if it could count at Zero speed, using RPM
instead of Oil pressure is only a rough approximation, of the required use of
a minimum Oil Pressure. In any case, the Flight Time, needs to be what is is
– ie FLIGHT TIME, and saved, so what appear to be missing is the 3rd Saved
Hours, TRUE GA Hobbs Time, a function of just OIL Pressure.

Hello @N6722C No, there no Hobbs time evaluated based on oil pressure rather
than RPM and speed. I have added a task in our backlog so that we expose some
additional parameters to do that or make the simvar writable to allow people
implement their own logic. Thank you for pointing out this issue. Regards,

Thanks Sylvain, Making both the SImvars that end up being saved in the
state.cfg file, writable, might be the best solution, as it would be backward
compatible with the existing aircarft, and allow for either of those saved
Hours that end up in state.cfg, to be controller by the plane developer, if
needed . Then there is the addition issue to be corrected, where the C172
Classic, display just one of those Hours in BOTH the Hobbs, and the RPM Hobs
Hour Counters, and that is set in the Model, so cannot be corrected by anyone
but Asobo. (Along with the Two Breakers that have invalid animation tags, I
mentioned some time ago, and you said you would get the developer/modeler to
correct - any idea when that may happen – ie Hopefully next SU update when
Asobo Premium Planes may get an Update/refresh - some of the DRM encoding
removed from their .cfg files ? ) Regards, Geoff
