What was he doing on a technicians course in the first place?
We are engineers and they are pilots I don't see it as being closely related at all.
I'd definitely fail a sim' check
Does that make me a bad engineer?
Pilots need to know how to safely operate an engine as a user, we need to know how to troubleshoot, maintain, replace and rectify them (and operate them on EGR's and Taxi).
That's my understanding
