Every Part 107 flight has exactly one remote pilot in command. Not a committee, not the client, not the person holding the controller if that is someone else. One person is answerable for the flight, and if you hold the certificate on a job site, that person is you.
The section is five short paragraphs, and the exam draws from all of them.
Paragraph (c) deserves a second read. The standard is not that you will not lose control. The standard is that if you lose control — battery failure, motor failure, radio interference, a bird strike — the aircraft still poses no undue hazard. That is a planning requirement. It is why you position yourself so the aircraft is never directly over the crowd, why you choose a takeoff point that is not in a parking lot, and why you know before you launch where a dead aircraft would fall.
Final authority is a legal term with a practical edge. Your client wants one more pass at dusk in gusting wind. Your site foreman wants you over the active crane. Your employer wants the shot. Section 107.19(b) makes you the person who decides, and § 107.23 makes you the person who answers for it if the decision was careless. Nobody who pressures you into a bad flight will be named on the enforcement action.
You are shooting a construction progress set. The superintendent asks you to hover over the crew pouring a slab so the client can see the finish work. Your aircraft is a 5-pound quad with no operations-over-people category. The correct answer is no, and the correct next sentence is an alternative: you can shoot the same slab obliquely from 60 feet to the side, or you can shoot it in ten minutes when the crew breaks for lunch. Final authority is easier to exercise when you arrive with a plan B.
Section 107.12 answers this and it surprises people. A person may manipulate the flight controls of a small UAS if either of the following is true:
The second path is real and useful. You can hand the controller to an untrained client, a student, or a crew member as long as you are supervising and can take over at once — typically through a dual-controller trainer link, or by taking the controller back. Handing someone a controller and walking away is not supervision. Standing beside them with a slave controller and your thumb near the override is.
The point that matters most: delegating the sticks does not delegate the responsibility. You remain the remote PIC. Everything that person does with your aircraft lands on your certificate.
A certificated remote PIC lets an uncertificated colleague fly the aircraft during a survey. Which statement is correct?
Answer: B. Section 107.12(a)(2) permits an uncertificated person to manipulate the controls under the direct supervision of a remote PIC who has the ability to immediately take direct control. TRUST is the recreational test and has no role under Part 107. The remote PIC keeps full responsibility under § 107.19.
Condition for safe operation — § 107.15. No person may operate a small UAS unless it is in a condition for safe operation, and prior to each flight the remote PIC must check the aircraft to determine that it is. The rule then adds a second, continuous duty: no person may continue flight when he or she knows or has reason to know the aircraft is no longer in a condition for safe operation. A vibration that starts mid-flight, a battery warning, a control surface that stops responding cleanly — the flight ends.
Medical condition — § 107.17. No person may manipulate the controls, or act as remote PIC, visual observer, or direct participant, if that person knows or has reason to know of a physical or mental condition that would interfere with the safe operation of the small UAS. Note the breadth: it reaches the VO and the crew, not only the pilot.
A common wrong answer says a remote pilot must hold at least a third-class medical certificate, or must be examined by an Aviation Medical Examiner. Neither is true. Part 107 substitutes a self-assessment duty for the medical certificate, and that duty extends to visual observers and direct participants — people who could never hold a pilot medical in the first place.
Section 107.61 sets four eligibility requirements. Subject to the alcohol and drug provisions of §§ 107.57 and 107.59, a person must:
You may take the test at 14 but you cannot hold the certificate until 16. Those are two different ages and the exam knows it.
The path after you pass looks like this: your Airman Knowledge Test Report is valid for 24 calendar months. You file FAA Form 8710-13 through IACRA, using the FAA Tracking Number you created before the test. The TSA runs a security threat assessment. When it clears, you can print a temporary certificate — valid for up to 120 calendar days under § 107.64 — and the permanent plastic card arrives by mail. The certificate itself never expires; what expires is your knowledge recency, covered in Lesson 1.10.
What is the minimum age to be issued a remote pilot certificate with a small UAS rating?
Answer: B. Section 107.61(a) requires the applicant to be at least 16 years of age. A person may sit the knowledge test at 14, but the certificate cannot be issued until 16.
Put your remote PIC designation in writing on multi-person jobs. A one-line entry in the crew briefing — name, certificate number, the phrase remote pilot in command — costs nothing and removes any argument later about who was in charge. It also forces the conversation on jobs where a client assumes their staff member is running the flight.
