Can someone explain why is it at EDI when you're cleared taxi to holding point D for departure, you're "
Clear to cross the 12 undershoot"????
I thought that when you're clear to proceed to D you are clear through the whole route to D and anything that's in the way. Then you have to read this nonsense back as well!!
Remembering that landing or taking off involves passing through that same silly undershoot 20 feet further away (the runway), but you're not told "clear to land/take off 24 and to fly through the 12 undershoot".
Please someone explain
