Would be grateful if you could provide a link to the State Letter. Have my doubts that it will have any positive impact.
An earlier change to OLS in Annex 14 did benefit SOU due to the reduction of runway strip width from 150 to 140 metres, which improved the obstacle limitations beneath the 1:7 Transitional Surface. This resulted in larger aircraft being able to park nose in Stands 7-12.
