OooOoookay. I think I understand
So either he has to,
Do the SEP to add to his ATPL which means trading in for an EASA one, all of which can be done online or in a couple of hours at Gatwick.
Or
He can separately apply for a LAPL, for which his Class 1 Medical is already valid with an SEP rating on it but that includes all the restrictions applied to a LAPL with regards to flying those types, then when it's time to renew his JAA ATPL he will change to an EASA one and include SEP as a rating...
I'll pass it on.
Purple Pitot, we're planning on doing it in the spring up in Inverness, we have a small mafia of bizjet/turboprop fruitcakes (i.e. you'd fit right in
). If you fancy doing it around then, PM me and we'll set things up for you up here
