I have also heard of the AVP moving south and the aircraft stands in it's place. This is what has been said about it.
'Land has also been identified within the extended operational area at
Cloughbank Farm to the west of the aircraft maintenance area. This
area affords direct access to the taxiway network and has the possibility
to accommodate relocated cargo stands or stands required for
overnight parking.'
I believe that the number of stands is 20 (narrow body) or 10 wide in a MARS config.
