Hello everyone, i wanna ask question about SAT, TAT, i know that you should turn on engine anti ice if TAT +10C or below and there is visible moisture (fog,clouds, rain etc) and turned off when SAT is at -40 or above.
So my question is should i turn on engine anti ice and probe heating, if SAT is -30C and TAT is -11C and there is no visible moisture, like cruising at 330?
