Hi there I wonder if someone can help. I'm using AS6 alongside a range of aircraft, and almost always during a flight the Airspeed indicator goes from the initial airspeed eg 250 knots down to zero. The same goes for the air speed shown in FS9 when you display it at the top of the screen. If you refresh the weather in AS6 the ASI comes back, (and then goes away again!)but it is a real nuisance as some aircraft are not happy with this, esp if you using auto-throttle!I have installed the latest upgrades of AS6 and use FSUIPC 3.53. No failures are set.Does anyone know how to fix this? I've looked through the forum and can find nothing similar. Thank you in anticipation. RegardsGraham

Reason: Icing...Fix: Turn on pitot heater or disable icing in ASv6 options.;-) JT

Nothing to do with Active Sky 6. You just using it in winter, that's all. Your pitot tube is icing for sure. Turn on the pitot de-icer and you should be fine.

Acually, I have had this problem as well. I suspected icing initially, but it occurs with pitot heating on. I get one drop, around the time AS6 gets busy, then it returns and will be stable for the rest of the flight. I wouldn't be too quick to dismiss this yet.

Hi,Some aircraft don't correctly enable the pitot heat system properly with cockpit-controlled pitot heat switches. In some cases I believe using the CTRL-H key manually will enable this (I may be wrong on the default keyboard shortcut, but it is the one for pitot heat). In other cases, anti-ice and/or de-ice must also be enabled to prevent pitot blockage (depends on internal systems programming).The only effect which brings ASI to zero is the pitot icing/blockage effect, which only occurs when "in" a cloud layer which has been set for icing. Certain clouds (thunderstorm, for example) will generate severe icing and potentially block your pitot tubes (and give plenty of airframe icing) regardless of anti-ice/de-ice or pitot heat. So if you were flying in thunderstorms this might be normal.Also, it being winter and all, many areas are prone to icing, and as in the past several years for us have shown, we will get several "Airspeed 0" support requests during this time due to the above issues.However, it is interesting that you note it only drops during weather updates. That indeed is strange, and something I have not ever experienced or seen reported until now. It might some something FSUIPC-related. Nothing in our icing processes have changed for quite some time. I will investigate with the latest FSUIPC, and would appreciate any other input as to how to duplicate (perhaps certain weather date/time and location/aircraft?).Best,

Same problem last night and pitot are on with MD-82 Lago, take of at 19h Zulu from LTAC Ankara Rwy03R SID Telvo on climb aprox 10nm inbound Telvo airspeed drop to 0LTAC 0 0 N40

Anybody have new information about this problem .. because i have always the problem with many aircarft: pssa321,md80 lago... etc this evenings take off from kmdt and i climb at 9600ft ias drop 2 or 5 minutes and pitot is on ...thanks for reply

Hi,Not that I am aware of. It seems to be something system specific for you. Do you have a registered FSUIPC? Did you adjust the icing level there?Can you try a default plane and see what happens?Hope this helps,Jimhttp://www.hifisim.comhttp://sales.hifisim.com/pub-download/asv6...development.jpg http://sales.hifisim.com/pub-download/asv6-banner-proud.jpg
