Dear Steve,
1, 2 I agree.
3. Yes, you have to click to acknowledge the eras report, or whatever they call it this week, but there is no way of providing feedback.
4. We record everything these days. Cvr, Qar, crew control calls, sim sessions.
Why not record your debrief? It is the only thing which may safeguard your career in case of a he-said, she-said situation.
Nothing to do with lack of confidence in your abilities.
I myself and a number of people I know have, at one time or another, been blind sighted and given a different eras report from the debrief.
Count yourself lucky, that you haven't had that problem...yet?
