FAR 91.109 — Simulated Instrument Flight
FAR 91.109 explains dual control requirements for flight instruction, safety pilot rules for simulated instrument flight, and ATP flight test seat requirements.
FAR 91.109 governs three related situations: giving flight instruction, flying under the hood (simulated instrument flight), and certain flight tests.
- Flight instruction generally requires the aircraft to have fully functioning dual controls. An exception allows instrument instruction in an airplane with a single throwover control wheel if the instructor judges the flight safe and the person manipulating the controls holds at least a private pilot certificate with appropriate ratings.
- A throwover-equipped airplane may also be used for a flight review (§61.56), recent experience, or an instrument proficiency check (§61.57) if rudder pedals exist at both stations, the pilot flying is qualified as PIC for the whole flight, and the instructor meets §61.195(b) and has at least 25 hours PIC in make and model.
- Simulated instrument flight requires a safety pilot in the other control seat with at least a private certificate (category/class appropriate), adequate forward and side vision (or a competent observer to supplement it), and fully functioning dual controls — with a throwover-wheel exception for single-engine airplanes.
- For an ATP flight test, class/type rating ride, or Part 121 proficiency check, the other pilot at the controls must be fully qualified to act as PIC.
This rule matters because hood time and instruction are core to building proficiency safely — knowing the safety pilot and equipment requirements keeps the flight legal and protects everyone on board.
