It is if you have to go thru the same old frigmarole every time you go on det! Having done 5 dets in theatre in the last 18 months (and lots of people have done lots more than that) I can safely IDT/IRT has nothing to offer except giving me one or two less to get sh*t together before going on det again.
Sorry guys, but for those of us who go there frequently it is a hinderance and a pain in the backside. When it reaches the stage that this IRT/IDT nause takes precedence over flying training and quals then someone has truly lost the plot.
Sure, first time out there go do all the trg. You'll only do it all again when you get in theatre but hey it's all good practice. But for the third, fourth and fifth times? Get real. Tail wagging the dog. As is fast becoming the norm these days.
