It will be interesting to see if the runway extension (given that planning permission is granted ) occurs with resurfacing and groving .On the subject of stands,I remember a A321 parked up on 13/14,facing out due to ILS infringement ,given this fact surely this 13/14 combination could be used as an additional stand for 320/738 operations.
If so that would give 5 stands as opposed to 4 for operation of a small LCC commitment.
