Just to clear up what specifically happens to arrivals to AVV in CTAF procedures at night. At approximately 30 NM AVV, aircraft are given winds at the aerodrome and asked intentions. Clearance to 3000' is given at the appropriate distance to AVV. Most times crews are given instruction to climb to 3000', instead of 2500', in case of missed approach. At 12 NM, last control zone step, crews are cleared to leave controlled air space via ILS, Localizer, VOR or visual approach (as per stated intentions). No landing clearance is given as such except reminder of SAR watch cancellation when clear of runway. If aircraft climb to 3000', recontact with Avalon Approach should occur to state further intentions. It would be best to confine comments to these procedures instead of comments at other destinations. Conjecture on what happened last week is only conjecture until the true facts are published.
