Anytime I use the Winter Wonderlane theme, at about 3000 feet I lose my airspeed indication. It just rolls back to 0. I am using this theme on a flight I created. I asked this question a couple of weeks ago, and the one rsponse I got said to turn the de-ice on, that did not work. This has happened on both a 737 and 747. I have used the clear weather theme and never have had this problem. Any answers would be appreciated. Thanks.Andy

You should turn on the pitot heat. Not the de-ice.Alex
