I seem to remember Bristows bonding some new blokes for a type rating and they left early, Bristows tried to get there money back but it ended up in court. The short of it all, if my memory is correct (know doubt someone in pprune will correct me if I'm wrong) is that you cannot be bonded for a type conversion if the company need you to fly there a/c, they can only bond you if they have paid for your initial license. Worth looking into ITI. Any Bristow or ex Bristow blokes (or birds) care to comment.
