Bunktime
As nobody in EK wants to tell you anything about DEC time although I would have thought those like Wiz would let me tell you what happens in SIA as an example for DEC's.
In SIA regardless of whether you were already rated on type (and most DEC's were not) you still did the full ground school and sim but were let off the circuits if already rated. Providing there was no delay in getting to the sim which in SIA often happened ( in my case being sent on two weeks forced leave after just finishing ground school) I was checked out on the line 3 months after joining. I would have thought EK would be the same kind of timescale??
