I'm surprised more comment hasn't been made on this FOI response. A quick read through the document makes it look highly likely that once you start on the path to officer aircrew, you will finish it. Chop rates look very low indeed.
97.8% pass IOT
87% (average across the 3 streams) pass to OCU
On the other hand, it does show how few even start the journey. Less that half the applicants walking through the door get invited to OASC.
What it doesn't tell us, and therefore doesn't really help the person making the request, is the OASC percentage pass rate. Does anybody have this final piece to the jigsaw?
