and updating my Jepps on Saturday afternoon like a good little Jaba, I noted the YMAV airspace was still C over D.
Sounds like planning was rather.......well ........ someone will have a word for it
I think the way it works is that for June maps etc. ASA release the data to Jepp and others sometime in Feb/March I think. There was also an AIC (H02/10) published back in mid-April that mentioned the change.
3.4 Avalon Airspace changes
AVALON Class C CTR is reclassified to Class D with surrounding Class
E airspace during hours of tower operation, and Class E airspace
replacing the CTR outside of tower hours. Refer to CTA/R airspace
amendments.
Contact Jepp and see what they say -
