Runway 02 could possibly have the TORA increased. Looking at Google Earth the proposed extension will require re-alignment of the current boundary fence in order to accommodate it. Assuming that there is only 164 metres to play with, subtracting the minimum 150 metres (strip end + 90 metres) that gives a potential TORA 1737 metres. I any of the land outside of the current boundary fence, as it appears that it is, anything that can be reclaimed by levelling it will be a bonus and possibly permit further extension of the 02 TORA towards the maximum 1799 metres.
From the airport website:
Our plans will not lead to an expansion of the airport site. Southampton’s longer runway and expanded parking facilities will be fully contained within the current airport boundary.
Is there an inconsistency here, are does the current boundary fence not represent the actual airport boundary?
