FAA Flight Instructor Airplane (FIA)Regulations (14 CFR 61/91)Medium

Two pilots agree to fly their airplanes in close proximity for a photography session, with no passengers carried for hire. According to 14 CFR 91.111, what condition must be satisfied before this formation flight is conducted?

  1. APrior arrangement between the pilots in command of each aircraft, and neither aircraft may be operated so close to the other as to create a collision hazard
  2. BA formation flight waiver must be obtained from the FAA regardless of the purpose of the flight
  3. COnly the lead aircraft's pilot needs to plan the flight; the other pilot may join at will
  4. DFormation flight is prohibited under all circumstances in the National Airspace System
Show answer & explanation

Correct answer: A. Prior arrangement between the pilots in command of each aircraft, and neither aircraft may be operated so close to the other as to create a collision hazard

14 CFR 91.111 requires prior arrangement between the pilots in command of aircraft flown in formation, and prohibits operating so close to another aircraft as to create a collision hazard. It also separately prohibits formation flight when carrying passengers for hire.

Why the other options are wrong

  • B. No general FAA waiver is required for formation flight outside of special use airspace or airshow contexts.
  • C. Both pilots in command must arrange the flight in advance, not just the lead pilot.
  • D. Formation flight is permitted with prior arrangement; it is not universally prohibited.

Formation Flight (91.111)

Aircraft may not be operated in formation except by prior arrangement between the pilots in command, and never so close as to create a collision hazard; formation flight carrying passengers for hire is prohibited.

  • Prior arrangement between PICs required
  • No operating close enough to create collision hazard
  • Prohibited when carrying passengers for hire

Memory trick: Fly in formation? Shake hands first — plan it, don't wing it.
