TAT probe indication - A320
During icing conditions the probe heat is selected when on the ground. The TAT probe is not heated in this case, so, my question is, how accurate is the SAT on the ground? I mean, if the ATIS is indicating zero degrees, but the SAT shows 2 or 3 degrees (after several hours sitting at the bay), is it ok to use what is indicated on this system?
Many thanks.

SAT and TAT probes are designed to operate when the aiplane is moving through air.
So when sitting still on the ground, they are not accurate and are usually off by 2-4 degrees celsius.
So on the ground, the only temp you SHOULD rely on is what is given to you on the ATIS or by the tower...
Its as simple as that!
