This is one of the complex obstacle limitation surfaces that are designed to protect the runway. However I understand that SOU may have been given some form of waiver from this by CAA.
Second problem is at least Stands 6-12 were constructed to take a lower weight of aircraft than Stands 1-5. Suspect that this also applicable to Stands 13-14.
Maybe someone out there who is still gainfully employed at SOU can elaborate.
1:5 transitional or 1:7 ? Methinks it is the latter old chap.
