Rivet Joint
Suprisingly enough the current take-off run avaiable (TORA) for RWY 02 (1723m) is greater than that on RWY 20 (1650m). This is due to a requirement for the latter to have a 60 metre overrun (the "strip end", plus a runway end safety area (RESA) ) for the same purpose and to protect the undershoot for the reciprocal runway. The latter ends about the top of the bank which goes down to the M27.
As mentioned in a previous post the RESA width is supposed to be twice the runway width. Due to the top of the bank running diagonally across the RESA, the full double runway width is not attainable for the complete RESA, hence the "fudge" that I previously mentioned. If/when the starter strip is installed CAA may insist on clawing back the missing part of the RESA width which will reduce the increase in 20 TORA from the intended full 170 metres.
In respect of any increase in 02 landing distance available (LDA), as the same applies to 02 (ie strip end + RESA) an increase of 20m may be possible, more is possible dependant upon any extra land (at twice runway width) available beyon the end of paved surface. To avoid a wing tip hitting a fence when the aircraft lines up, one must assume that there will be- hopefully this has been considered??????
