Ok, lots of good ideas and help with starting a charter operation - thanks. One more question though: Do the same rules apply if you're just using the plane in support of your business? i.e. Using an aircraft to support my adventure/tourism venture - carrying tourists from the town to the country lodge; transporting canoes/kayaks/supplies to location. Do I still have to go through the same process and paperwork that I would were I to operate my aircraft for miscellaneous charter? Thanks again for your help.
