Just to clear things up regarding the original post, given that I'm an ex-UAS stude enjoying the wonders of EFTS groundschool as we speak......
1. On the UAS you are not issued with a Dalton Computer, and not told how to use one either.
2. Following IOT, pilot studes undertake 4 weeks of groundschool at Cranwell where we ARE taught AND examined on how to use the machine and get issued with one.
We then head for Tucano, Squirrel, King Air etc.
Direct-entry RAF studes (plus Navy and Army) get the groundschool BEFORE they do EFT at the UASs or DEFTS.
Hence why your UAS stude didn't know how to work one. So as the UAS stude could not apply for a PPL using his Grob 115 flying until after groundschool, you can feel assured that all exemption-using RAF pilot studes do know how to work the Dalton.
