SkeyeMentor explanation
Educational — not an FAA sourceIn plain English
Prohibits operating so close to another aircraft as to create a collision hazard, and restricts formation flight and carrying passengers for hire in formation.
Why it matters
Formation flight is legal only by prior arrangement with the pilot in command of each aircraft — an informal "let’s join up" does not satisfy this.
Quick example
Two friends want to fly wingtip to wingtip for photos with a paying passenger aboard. Read paragraph (c).
