Suggest you a gander at the following sites;
BBGA - The British Business and General Aviation Association, EBAA.aero & NBAA.aero
The public areas should give you a quick ref, also get hold of EBAN mag (
ebanmagazine.com) & Aviation Int'l News (AINONLINE.com) & if you can check BART mag (bartintl.com) as well as Fly Corporate mag (flycorporate.com)
