Thanks for your thoughts on this and sorry not to have replied earlier but I wanted to check the temperature readings on the plane before doing so.
You are at least partly right: the readings on the ground are 2 deg C apart and I will get the sensors checked at the forthcoming annual.
Yesterday at FL120 and 160 KTAS they were up to 7 deg C apart and, later on the way back, at FL90 and 155 KTAS they were 6 deg C apart.
The sensor on the wing seems to be right because I started to see some icing when entering cloud with a reading of -3 and the ice cleared as the indicated temperature rose above 0 Deg as I descended to get out of it. The TKS system did a good job of keeping the leading edges of both wings and elevators clear whilst I was getting clearance to descend.
I don't know if this sheds any light but would be interested to hear your further thoughts.
Many thanks
John
