as the TAT probe freezes the indicated temperature increases toward zero - ice temperature in a static airflow
A plainly incorrect statement - as it presumes that ice will be at zero (presumably Celsius)
at any ambient temperature!!!
In any case - I am aware of the icing conditions and engine effects in the links you posted. You appear to think that that is the only possibility for engine rollback, and indeed dismiss high altitude temperature increases as misunderstood icing events. The science for high altitude warming is well understood - and there is no evidence that the JJP 146 event (certainly) was an icing event. Both events occur, both are rare.
