Don't we have enough paperwork to fill in and/or rules to follow.
Now if I have to take the LPC of someone who does not have the same state of license issue, I need to get the approval of that state to be able to do his LPC.
In my company our pilots have license which are issued from all european countries, it's going to be a nightmare to ask every state to be approved to do the exam. Even if this is only a one time brief, that's going to be impossible to follow and probably adding an extra fee every time !
i thought that it was working perfectly within the JAA system (At least at a TRE level for LPC on MPA), you just needed to know which license you could revalidate yourself by signing it and those who did not allow it.
