TAT indication

[George Papanikolopoulos]

Is it normal when flying the B737-700 with all the latest builds, at FL320
and Active Sky showing -37 C at that altitude (and appr. 20-25C on ground),
to have only -5 C TAT indication in the PFD display?

Hi George,
TAT = Total Air Temperature, so it's also takes friction head into
consideration, but -5° on that altitude doesn't look very realistic.
Ciao
