Where is probe heat  on/off switch on Overhead panel?  :D

In the real 777 there is no probe heat switch. Probe heat is automatically applied when the first engine is started.

So CS would have to simulate this in their 777, too. Apparently, as judged by your post, they haven't.

It's the same for the fuel mixture: There is no fuel mixture lever on a jet aircraft. Still MSFS wants the fuel mixture to be set to '(full) rich' to start your jet engine. Unfortunately, CS hasn't coded this command either ...
