IAS INDICATOR

[andrewgeorge60]

Hello everyone.  I Decided that i fancied a challenge, i decided to set the weather to heavy snow.  I was flying a 737-700 (The one by moach).  I completed all the checklists and checked all of the instruments.  i got about 9 miles out of EGCC Manchester England.  The IAS simply reset to 0.  So did the stand by.  I couldnt fly the aircraft safely so had to turn back for a touch and go.  This happens with all aircraft, but only in heavy snow.  Any ideas, im lost???

Thanks,

Andy

ICE !

(turn on the pitot heat) (It's an electric heating element that keeps (or melts) ice from forming in/on the pitot-tube ( the device the IAS gauge uses to measure airspeed))

Thanks, I thought i had done.  I went through the checklist!! does anti ice and pitot heat need to be on or r they the same things

I'm not sure how FS9 ties that together.. I'd imagine if you need anti-ice for the airframe and/or prop, you'd need it for the pitot-tube also.. If in doubt, just use the key-board shortcut for turning on pitot heat.. OR.. install a seperate pitot heat switch on the panel.
