Has to be teaching student instructors (military) to teach EOLs. In the CFS(H) system, on the various exercises the staff instructor plays the part of the student, and injects deliberate errors for the student instructor to identify and correct.
So there you are, deliberately getting an EOL wrong, so your student can correct it! And if he doesn't ....... 'cos you're still captain/PIC!
More comfortable in the Squirrel with the throttle in yer left hand rather than in the Gazelle with it in the roof!
It wasn't called "Lemmings' Day" for nothing..........
