Not sure what the pay is like. Fair I suppose. (Sorry, couldn't resist..)
The exam wasn't the ATP exam. It was actually the 'Private Pilot Aviation Law' exam. These blokes I think had been well prepped by ANA sources for the ATP but not for the AvLaw judging by their comments afterwards. I'd estimate there were only about 5 out of 20 questions that were common knowledge questions and the others seemed to be Japan-specific i.e. what's the max speed of a piston aircraft in the 'control zone'?
