All three similar schemes (Kura, CTC and Wings Alliance) have pass/fail selection. The reason for this is the variable quality of candidates. To be fair, in all three schemes the main fail point is the selection process before the sim phase (group exercises, interviews, review of training records etc.) not many candidates are expected to fail after that, but it is possible. The selection processes are all different and sometimes a candidate fails one and passes another. As an example, Wings Alliance had a candidate that we thought was very good but had already been failed at the selection stage with Kura. Happily that pilot now has a job with Stobart, so it worked out.
