(d) an aircraft that is flying or operating for the purpose of, or
in the course of:
(i) the personal transportation of the owner of the
aircraft;
(ii) aerial spotting where no remuneration is received by
the pilot or the owner of the aircraft or by any person
or organisation on whose behalf the spotting is
conducted;
(iii) agricultural operations on land owned and occupied
by the owner of the aircraft;
..............
shall be taken to be employed in private operations.
Pretty sure that means that an aircraft owned by a station and flown on the station land or flying the owner of the station around is therefore legally a private flight and as such his PPL would be enough right?
Irrespective of whether he is getting paid extra to fly it or not, it still counts as a private operation...though i'm sure some lawyer boffin would argue otherwise somehow!! I ain't no lawyer, just giving my interpretation, always happy to be proven wrong and learn something
