Hi Dominican
Maybe crap to you and moi, however to JCAB of the utmost importance!
As you would have realised well and truely by now paperwork is paramount - the ability (or lack) to actually fly and command the aircraft almost - I do say, in fairness, almost - a curious western ideology.
Of course with your in-house T&C the JCAB is merely a jumble of letters to you now - maybe yes, maybe no, maybe maybe......??
Glass not new (doesn't mean still can't get cut) but couldn't find answer easily via Mr Boeing - although sure it's there, somewhere.
Appreciate your time
cheers
