Licensed aerodromes
My understanding is that all approaches to non-licensed aerodromes are being withdrawn - it's not the survey that is the issue, it's the cost of keeping the aerodrome going. YLIL RNAV approaches have also been withdrawn, presumably for the same reason.
What should happen, for training etc, is that YPID NDB/VOR approach should be replaced with a CWS non-aerodrome approach like Yarowee - given that the inbound leg of both approaches puts you over water, there is no issue with continuing the descent to minimums (raised to 1360ft) then missed.
Why it should be done eco victim? Sure, there are others around but YPID as a training aid? It's the closest to Melbourne that doesn't involve stooging around in controlled airspace and stuffing other legitimate users.
MB - CTA/noise
EN - CTA/traffic/ML
AV - CTA/traffic
All the others - bloody miles away!
plus PCK - bloody dangerous!
It also serves as a way home for YTYA pilots who could break visual and track up the channel to Tyabb.
Bring back CWS/YPID approaches!
