"Jumping the Bovingdon Stack"
Folks,
"Jumping the Bovingdon Stack" in mentioned in the British Midland DC9 thread on the AH and N forum.
Would any ATCO like to explain? I'm guessing that, instead of having to cross BNN at 6000ft as per the SID, an aircraft with a "sporting" rate of climb could cross higher, with the lower-level holding traffic underneath, rather than above. Alternatively, I could be deeply misled.....
Hopefully I'm safe here. Mods - please don't move me to the ATC forum. I'm still in therapy from the last drubbing.
