Don't feel sorry.... The majority of us only use it on first contact with a new ATC freq. It's actually required in many FIRs; may stop your light twin being vectored too close to us and giving you a nasty surprise
By reading the weekly incident reports it seems that the whale itself is the one with the most botched landings and complaining about wake turbulence ...... even behind the 'light twins'!
Or is it a drivers problem?
