In the absence of a further NOTAM to delay its use, and looking at the approaches flown on 02 this morning (on he runway centreline, well east of the VOR/DME final approach track), I would say that the RNAV IAP is now being used.
An acquaintance of mine (who doesn't like aircraft) recently purchased a waterside property on the Itchen, notwithstanding my advice that he'd shortly be under the approach path. Could shortly be an addition to the local anti-airport NIMBYs?
How long do we have to wait for a 20 RNAV IAP?
