Some years ago but remember having to take off from a snowy DUB in a -400, just after they'd reopened for an Air Ambulance flight.
The CLEARED WIDTH was 30m. The airfield was to be closed again indefinitely for snow clearance afterwards.
Only other OM restrictions were a snow banks limit of, IIRC, 50cms., no crosswind and usually braking/reverser restrictions.
(Strange thing was that ATC would not allow a Fungus 73' to depart, saying conditions were outside his limits ???)
