The CAAP about landing areas was only advisory and looking at the regs I could only find this:
(1) A person must not land an aircraft on, or engage in conduct that causes an aircraft to take off from, a place that does not satisfy one or more of the following requirements:
blah blah
(d) the place (not being a place referred to in paragraph (a), (b) or (c)) is suitable for use as an aerodrome for the purposes of the landing and taking‑off of aircraft;
and, having regard to all the circumstances of the proposed landing or take‑off (including the prevailing weather conditions), the aircraft can land at, or take‑off from, the place in safety.
Faark, your regs are a bit anal. Over here you can land anywhere you like so long as you have the owners permission. It goes without saying the place of landing must be suitable for use as such.
