13/31 is the only licensed runway at Chalgrove. 06/24 and 18/36 are not licensed.
Why would a private GA flight require a licensed runway? The other runways do not have crosses prohibiting their use. The Licensing is for the airfield operator Martin Baker a company World famours for their own IFR let down systems! The licensing is also irrelevant to any military use of the airfield.
The entire site has been sold by the MoD
It would not be the first time the MOD had attempted to sell land they may not own, Halton and Wittering come to mind!
