RE: Does
It all comes down to what the`FAA defines as "business purpose"........
The only references I could find were references to the US IRS rules as to "business purpose"....... IF that is the definition then if the activity of the pilot either generates taxable income or tax deductible expenses then it is a "business purpose".
So I would think one measure would be using the example of attending a RC event:
If as the pilot you receive income or other remuneration for attending he event it is "business purpose"
If as the pilot you expense some of the cost for taxes you have declared "business purpose"
Say you own "Great BIG RC Hobbies" and attend an event and also have a vendor booth at the event, does that make any flying at the event "business purpose"?
Gets very interesting and complicated.
