The ILS maps from the CAA show the long approach being right over Sellindge. The flight paths have been overlaid onto an aerial photomap in an attempt to make it more understandable where the flight paths actually are/would be. The flight path above Sellindge seems to be around 2000 to 3000 feet. You can see aerial photomap described in the right-hand column, at the top of the 'Recent Updates' section (5th coloured section down). Just click on the link entitled 'Lydd Airport expansion Flight Path' to view. Once you have finished click on the back arrow at the top of the screen to return to here.
