How long is the runway? , Will it be extended to cope with an E170 or c series for Example.
Runway distances are shown on NATS AIS,
Dimensions 1837m x 30m
25 TORA 1714m, TODA 1824m, ASDA 1714m, LDA 1469m
07 TORA 1649m, TODA 1777m, ASDA 1649m, LDA 1311m
but to extend east ward will require a road diversion and put the final approach lower over the village of Irthington which is 600m from the existing end of the runway.
The other way the main M6 - A69 cross country road is 400m from the end, as well as another minor road being in the way.
So no I doubt the runway will ever get extended
