1. 1Which operation falls within the general applicability of 14 CFR Part 107?

   1. A. A civil small UAS inspection flight in the United States, with no applicable exclusion
   2. B. An air carrier operation conducted in the United States using a small UAS
   3. C. A recreational flight conducted under the provisions of 49 U.S.C. 44809
   4. D. A flight elected under Part 91 using a small UAS with an airworthiness certificate

   Answer: A

   Explanation: "this part applies to the registration, airman certification, and operation of civil small unmanned aircraft systems within the United States." The inspection flight is within the stated scope. The other operations are expressly excluded by paragraph (b).

2. 2Which airspace class generally surrounds the nation's busiest airports from the surface to 10,000 feet MSL?

   1. A. Class B
   2. B. Class C
   3. C. Class D
   4. D. Class G

   Answer: A

   Explanation: "Class B airspace is generally airspace from the surface to 10,000 feet mean sea level (MSL)" This describes the usual Class B structure; individual published boundaries still control.

3. 3Which product reports observed current surface weather rather than a forecast?

   1. A. A TAF
   2. B. A METAR
   3. C. A winds-aloft forecast
   4. D. A forecast surface-prognostic chart

   Answer: B

   Explanation: "A METAR is an observation of current surface weather reported in a standard international format." METAR is an observation; the other products forecast conditions.

4. 4A small UAS is loaded to its published maximum gross weight. Why must the PIC still evaluate the day's takeoff and climb conditions?

   1. A. Maximum gross weight guarantees full climb performance in all weather
   2. B. Actual conditions may require a lower operating weight
   3. C. The published limit applies only to the empty aircraft
   4. D. Payload weight does not affect performance after takeoff

   Answer: B

   Explanation: "the aircraft may not always safely take off with this load under all conditions." The published maximum is not a guarantee for every combination of altitude, temperature, humidity, obstacles, and launch conditions.

5. 5What is a CTAF used for at an airport without an operating control tower?

   1. A. Obtaining radar separation instructions for the airport traffic pattern
   2. B. Broadcasting and monitoring airport traffic advisories
   3. C. Receiving individual runway-entry clearances from other pilots
   4. D. Transmitting only to request services from the airport's operator

   Answer: B

   Explanation: "A CTAF is a frequency designated for the purpose of carrying out airport advisory practices" CTAF supports airport advisory practices. It does not turn pilot transmissions into ATC separation or runway clearances, and its purpose is broader than requesting operator services.

6. 6Under Part 107, what is a control station?

   1. A. The aircraft's onboard navigation receiver
   2. B. An interface used to control the aircraft's flight path
   3. C. A ground location providing air traffic clearances
   4. D. The observer's position for monitoring nearby traffic

   Answer: B

   Explanation: "means an interface used by the remote pilot to control the flight path of the small unmanned aircraft." A control station is the pilot's flight-control interface; it is not defined as a navigation receiver, ATC facility, or observer location.

7. 7Which radius combination normally describes the inner surface area and outer shelf of Class C airspace?

   1. A. 3 NM inner radius and 5 NM outer radius
   2. B. 5 NM inner radius and 10 NM outer radius
   3. C. 5 NM inner radius and 20 NM outer radius
   4. D. 10 NM inner radius and 20 NM outer radius

   Answer: B

   Explanation: "the airspace usually consists of a surface area with a five nautical mile (NM) radius, an outer circle with a ten NM radius" The usual Class C radii are 5 NM for the surface area and 10 NM for the outer shelf. Individual published boundaries still control; the alternatives substitute different radii.

8. 8How should a remote pilot interpret the METAR wind group 22012G20KT?

   1. A. Wind toward 220° magnetic at 12 knots, with 20-knot gusts
   2. B. Wind from 220° magnetic at 20 knots, with 12-knot gusts
   3. C. Wind from 220° true at 12 knots, gusting to 20 knots
   4. D. Wind toward 220° true at 20 knots, gusting to 12 knots

   Answer: C

   Explanation: "The first three digits indicate the direction the true wind is blowing from" Wind is from true 220°; 12 is sustained speed and G20 is peak gust speed.

9. 9A payload moves aft without changing total aircraft weight. Which assessment correctly addresses the resulting balance risk?

   1. A. The CG remains fixed because the total weight is unchanged
   2. B. The CG moves forward because weight has been moved aft
   3. C. The CG can move aft and must remain within allowable limits
   4. D. The allowable aft-CG limit automatically moves with the payload

   Answer: C

   Explanation: "its location depends on the distribution of aircraft weight." Weight distribution controls CG location. Aft relocation can change balance even with unchanged gross weight; the aircraft's allowable limits do not shift to accommodate it.

10. 10At a non-towered airport, what service may a UNICOM station provide?

    1. A. Issuing binding runway assignments equivalent to tower clearances
    2. B. Providing radar separation between participating airport aircraft
    3. C. Giving airport weather information and a recommended runway
    4. D. Authorizing pattern entry with priority over other arriving aircraft

    Answer: C

    Explanation: "UNICOM is a nongovernment air/ground radio communication station which may provide airport information" UNICOM can supply airport advisory information. A recommended runway is not a tower clearance, radar separation, or priority authorization.
