EASA ATPL includes LAPL privileges (at a matter of interest EASA PPL currently does not include LAPL privileges) so as long as you have a valid medical and the requisite hours you may exercise the privileges of the LAPL.
As airpolice says, every day's a school day.
My imperfect understanding is that a LAPL implies single engine piston. I thought that if you had an ATPL, you still needed a SEP RATING in order to fly a say, Cessna 150. If you choose to exercise the LAPL privileges of an ATPL, does that bypass the requirement for SEP rating?
Interesting about the EASA PPL not including LAPL privileges. We've had folk thinking they can fly under LAPL in their 2nd year of medical, 'cos it says so on their certificate. Wrong at the moment...
