I've told a few lighties in the past who are insistent on following very closely behind me in the Q400 'just be aware, we give out a lot of wake'. But only when, as mentioned in previous posts that the light plane driver isn't really taking the wake stuff into consideration. I don't think guys say it as a wank thing on purpose - it's that missing thing in aviation...what is it again? Oh yeah - AIRMANSHIP!
Ask the Rex cadets at Wagga how much wake the Q400 provides. You'll find the answers pretty entertaining.
