It read in the 50's or 60's (F) no matter how cold outside. That *did* do wonders for my calcuated TAS :). I spoke to GRT (I have an EIS 6000) and they told me to get it away from the fuselage. So I relocated it to the outboard inspection cover on the bottom of the right wing. It was a bit of a chore snaking the wire through the wing but now it works like a champ and gives believable readings. One downside to this location is that while parked or taxiing on hot blacktop you will get false high readings due to reflected heat from the blacktop. That's not where I'm usually concerned about either icing or airspeed.

I have a Dynon Skyview and it says do not locate the probe in the sun which rules out the top of the fuselage, in the vicinity of engine heat which rules out the bottom (exhaust) or exposed to cabin heat at the rear of the probe which nixes the clever idea I saw one dude use by mounting the probe in the cabin air NACA inlet. Now I don't have a clue. Any input appreciated. GC LFG -- For archives and unsub http://mail.lancaironline.net:81/lists/lml/List.html
