As an occasional hirer from a club aircraft fleet, I got used to the phrase: “It always does that!” when discovering a snag.
’Well I don’t get used to it. In fact I’m not very good at handling “grey areas” at all.
Luckily for me they had a very good and understanding engineering group who were always helpful and I was always happy to wait while things got “adjusted”, however I’m not sure if the CP was impressed. I’m sure he labeled me a pain in the arse.
