My reading:
CAo 95.55:
9.1:
i) a relevant aeroplane must not be flown over a populous area or a public gathering unless:
(i) a certificate of airworthiness under regulation 21.176 of CASR is in force for the aeroplane; or
(ii) the requirements mentioned in paragraph 9.7 are complied with in relation to the aeroplane;
And 9.7 says:
(b) in the case of any other aeroplane:
(i) an experimental certificate under regulation 21.195A of CASR, or an SAB flight permit, must be in force for the aeroplane; and
(ii) an approval authorising flight in the aeroplane over a populous area or public gathering must be in force under regulation 91.045 or 91.050 of CASR, which approval imposes no conditions or limitations that would prevent the flight.
..And the certificate says, among many other things:
18. Operation over a closely settled area shall be avoided at all times.
and separately,
20. The operation over a built up area of a town or city is subject to:
-- at a height and speed being able to glide clear of persons or dwellings.
None of this makes sense, I'm missing something.
- You CAN operate over a closely settled area if its unavoidable?
- You CAN operate over a built up area?
Isn't a built up area a closely settled area? Who decides what is unavoidable, my wallet? My passenger? My need for a toilet stop?
The SAAA has a paper that applies to their aircraft which makes sense.
