I haven't did a TR yet on a jet so I'm only working from what I've learnt.
As I understand it after base training you go into line training for a minimum of 68 sectors with a training captain in the LHS, you in the RHS and a safety pilot in the jumpseat in case something happens to the training captain. Once the training captain is happy with your competency (around 68 sectors) he 'Line Checks' you and you are then cleared to fly with an ordinary line captain and no longer require the safety pilot in the jumpseat hence 'safety pilot release', this is the point at which Ryanair start to pay you as I understand it. This is the general procedure for any airline.
Any current FR pilots on here able to clarify this?
