in my limited personal experience of this airline recruiters are generally only interested in aeroplane (and possibly helicopter) hours. Anything else (microlights, gliders, whatever) is in the "well I guess it's something to chat about during the interview" pile. I have separate log books for my (thousands of hours of) non-aeroplane flying and they have never even been looked at at an airline interview - all they were interested in was the aeroplane hours.
