P 51 Mil and Civ Airspeed indicator blockage

[Yossarian1943]

Hi all,

currently using Prepar3d V4 4.5.1230293 all modules, together with Active Sky Version 7070 for Prepar3d V4.

From time to time I noticed that my airspeed gauges stop working. The needle is in "0" position like the pitot tube is iced.

I cannot bring it back to live. It seems that the pitot heating is not working.

I noticed the same issue with the Spitfire.

Never had this kind of problems with FSX and Active Sky.

Any suggestions or ideas anybody?

Thanks for assistance.

best regards

Marc

Hi,

I don't have P3D, I use FSX with an outdated version of Active Sky (Next), but this is a known issue for at least my build of Active Sky. It has to do with how AS handles probe icing outside of the default WX engine. If AS determines that icing conditions exist, and the probe is not heated, then AS sends a signal to block the probe. For some reason subsequently turning on the probe heat does not clear the blockage. Myabe a communication breakdown with AS, or just simulating a blockage past the heating element. The solution is to be much more proactive with Pitot heat and use it as an anti-icing system (preemptive) and not a de-icing system (reactionary).

Perhaps newer builds behave similarly, you have to check with HiFi. It forces you to act more realistically anyways.

Hello Marc,

yes as flapman mentioned, I believe this is a known issue or feature of Active Sky making it possible to ice up a tube that cannot be cleared as can happen in reality.
