And now that I'm thinking about it, is there any explicit provision in the ANO or EASA-FCL that says that the experience hours required for issue or revalidation of a license/rating/whatever, need to be flown legally?
Unenforceable if so ... how many (VFR) flights have you been at 3,001' and not absoulutely certain that that cloud above you doesn't start below 4,001', just to pick a simple example?
Oh, and a possibile interpretation of Mona's OP is that the pilots only discovered after landing that the one doing the flying hadn't been insured! - what then?
