Hi, I've spent hours trying to research this area regarding flying within 50m of a vehicle without much luck. Paragraph 2c states: must not fly within 50 metres of any vessel, vehicle or structure which is not under the control of the person in charge of the aircraft. How do you all interpret "under the control of the person in charge of the aircraft" An example. 1) If someone I know was on a quad bike and I told them to drive to a certain point, turn round and come back again. Yes? 2) A car was travelling down a non active closed for the day 1.5 mile runway at an event. Strictly speaking not in my control this one so I may well have to keep the minimum 50 metre distance. Or depending on what you all think in control is?? Initially I though in control was driving. vessel...yes, vehicle....yes, structure....no. What's your thoughts or does or does anyone have a link to more info?
