does FS9 simulate this? I don't think it does, but i'm just curious :)

Yes it does, but rather badly.Bob ScottATP IMEL Gulfstream II-III-IV-V L-300Santiago de Chile

Although I'm not sure if it simulates icing on the wings but I can atest that it simulates pitot icing, On many many occasions I have seen the ASI go to zero in a climb or during cruise. Although I dont beleive In real lifwe it would just go staright to zero in one shot but I can be wrong.

I think FS2004 does simulate wing icing, but in stock form you don't often get the right conditions perhaps. I have ActiveSky 6 and I've definitely suffered wing icing problems flying an ATR into a storm area - loss of power, loss of lift, had to descend to 2500 feet to avoid falling out of the sky! I think AS6 makes the conditions more likely, but doesn't alter the effect of icing.

yup, can agree that FS2004 simulates wing icing. When using FSUIPC there are several options that effects icing, on the clouds page one can set how icing applies. It also depends on the aircraft you fly. With the default C208 the wing icing effect can be seen and also with the B18 from Milton Shupe. I tried both planes with custom weather settings within FS9 to simulate extreme icing conditions. Both mentioned planes have devices installed to deice the wings. On the same conditions with the PMDG 747 there was no way to deice the plane.The actual ice weight/or if icing applies can be observed with the small little tool called AFSD.On the test with the PMDG 747 i had several hundred kilos ice on the wings and with all devices switched on i had no chance to eliminate the ice from the plane. On the B18 when switching on the de-ice button i could observe how the ice load decreases down to zero kilos.Hope this helpsRon

Hi,FS9 certainly models some form of icing as the airspeed indicator will stop working if the pitot heat is not applied and once pitot heat is switched on the airspeed indicator will start again! which I suppose could be said to be the icing on the cake. Sincere apologies.Andy.

do you loose controls? or they become non responsive?i do have AS6 and buncha planes that should have it (icing stuff)

Hi,I don't think to that extreme. I do know that planes weigh more and you can get into stall conditions much easier.Jimhttp://www.hifisim.com/Active Sky V6 Development Team Active Sky V6 Proud SupporterHiFi Beta TeamRadar Contact Supporter: http://www.jdtllc.com/AirSource Member: http://www.air-source.us/FSEconomy Member:http://www.fseconomy.com/

Since you have AFSD, you can observe the actual effects of icing. Cdi (Induced Drag) increases. You have to fly faster (if you can) to even stay aloft. Angle of Attach increases with wing ice if you stay at the same IAS. Prop efficiency drops. Prop deice (when working) brings it back up to the nominal 80% to 85%. Displayed in another AFSD window. And, carb ice shows in the AFSD 'Power' window. With a CS prop, RPM doesn't drop with icing, so it's harder to tell than with a FP prop. Ron (also)

Jim; You probably know a heck of a lot more about this than I do but...my limited experience with it in 2002 and fs9 are that while it's notvisible on the default aircraft, airframe icing will occur withinroughly the same conditions as it would in real life. In other words, it must be enabled, the temp/dewpoint must support,and precip/visible cloud must be flown in to get it to accumulate. At least thats been my experience.
