So there I was in the VCR this morning while TEAM was is progress.
We get 10 DME checks on inbound a/c to the departure runway. (sometimes!

)
However, we have to protect the Glide Path critical area out to 15 DME.
So what happens if an a/c at 11-15 miles has a bit of a nasty because of a dodgy GP indication.
Who's at fault?
