Flying on Business
Much of general aviation activity in piston-powered airplanes is for recreation-the proverbial $100 hamburger ($1000?) on nice sunny weekends. Still, there are many general aviation pilots who fly-using the technical phrase-for the furtherance of business. Were not talking banner tows, flight instruction, skydiving, or true commercial endeavors. Furtherance of business denotes those operations that are only incidental to that business or employment. (14 CFR 61.113)
