RNAV doesn't suffer the limitations of a SRA or NDB. It will allow the 'UW' and the 'EDN' to be removed, which are significant costs. In terms of the limited times that 12/30 is used, RNAV will make it easier for the pilots and controllers alike. There's a lot of verbal in an SRA.
Does anyone know whether the five new stands that are being created at Block 33 (the turning area at the SE end of 12/30) are temporary or permanent? Do they have / will they have permanent floodlighting or will the floodlighting be temporary and portable? Permanent floodlighting would presumably prevent any future use of runway 12/30, unless it is designed to fold flat or otherwise be removed when necessary.
Perhaps an arrangement like the movable palm trees in the Thunderbird 2 launch sequence might work.
