'Pay as you Go' Line Training
Remember that once you are Line Training, and have been 'released' (from the Safety Pilot), you are now earning money for Easyjet (or Ryanair or any other 'Pay as you Go' airline. You are taking work away from an experienced pilot for the sake of profit for the airline
This is an abuse of a privilege provided by the regulatory bodies to allow the continuing training of professional pilots. It is not meant to be a revenue earner for an airline and the CAA / IAA / EASA should stop it
