Hello,
I'm trying to make sure I understand the gate mentioned in the STAFA documentation:
Traffic departing Manchester (EGCC) and Liverpool (EGGP) requesting FL200 or higher should be positioned by Stafa Sector to the west of Honiley, making use of the airspace extension to the west of L15 and L151. Traffic should be positioned within a ‘gate’ from 6NM west of Honiley to 2NM from the western edge of controlled airspace.
I've attempted to draw what I think are the east/west boundaries of this gate using the range tool, have I understood correctly?

Many thanks,
Alex
