An airfield would be classified as PRIVAT if there was reliable information as to the operator/owner. That can be a cattle station (grazing), research institute, outback school, aborigine reserve, holiday resorts & outback public places to name just a few. If the operator/owner can not be located and the aerodrome appears to be well maintained (markers, windsock etc) it should be classified an ALA. In some circumstances it may be NONE SPECIFIC, meaning the operator/owner is known, the airport is available to the public but it is not listed in an official national airport database. An airport with status UNKNOWN is usually marked as DISUSED. Permission to use private airfields are always required unless it states other wise. Airports marked as PUBLIC are usually published on the national air services website with reliable updates.
MID AIR COLLISION
There can be no doubt a mid air collision particularly in a class G (uncontrolled airspace) is a real possibility. Especially close to VFR approach points and airstrips where traffic converges. The see and avoid is the usual procedure with some competent radio work but often this is not enough. When venturing out for a bit of local fun flying it is always a good idea to make prior separation arrangement before flight planning with other known pilots. This could be a horizontal, a vertical separation or both. One pilot may fly at a slightly diff and more.....
