Flypast or 'Display'
A question.
If a privately owned aeroplane does a 'flypast' of an event, by which I mean it flies past/overhead the event at a legal height, in a straight line or doing a gentle turn, without then returning to the vicinity of that event, would that be considered a legal operation - a 'flyby' or 'flypast' ?
(Presuming no-one involved has any 'display' authorisation of any sort.)
It seemed to me that would be legal, even if not necessarily well advised - assuming all the relevant care was taken with regard to numbers of people at the event and suitability of forced landing areas.
Now - suppose that three aeroplanes in a loose gaggle did the exact same thing, would that be legal or would that be pushing the boundaries of acceptable practice? That seems to me to be more dubious. Any thoughts anyone. please?
