Thanks for reply, Genghis the Great
From what I've read here, RE the FAA vs JAA/UK CAA differences, ehm.
So it's bit exaggerated, right? I know that some hours as PIC in FAA are not considered P1 in JAA. I don't know other exact details of filling out logbook differences.
Pretty much any commercial standard logbook, so long as you fill in all of the basic flight data and use approriate column headings, will meet all of the requirements of any regulatory authority, and CAA and FAA don't seem to object to seeing each others stamps and signatures in my logbook.
BUT, this should cover these doubts..
As you mentioned, you use CAA logbook for many things.
Seems I'd probably go for separate logbooks. I don't fancy copying the data to PC and all around (besides photocopied backup) as I know myself a bit.
Can I 'carry forward' half empty logbooks into another one? Ie, when I finish up my CPL trainings and do instructing or focus on one side of flying for the time being.
Fake Sealion just mentioned RAF and RN logbooks data carried forward.
I don't know if 'merging' logs doesn't have some rules.
Is CAA or FAA logbook better for gliders?
