Part 107 Test Questions (41 Sample Questions Explained)

31 According to 14 CFR part 48, when must a person register a small UA with the Federal Aviation Administration?

A. All civilian small UAS weighing greater than .55 pounds must be registered regardless of its intended use. [See 48.1 and 48.15. This is the reason why the registry will be found illegal because it went after model aircraft ALSO which are protected because of Section 336. See my article on why the registry is illegal. Until it gets struck down, this is the law we have to know to pass the test! J]
B. When the small UA is used for any purpose other than as a model aircraft.
C. Only when the operator will be paid for commercial services.

UA.I.B.K1 Registration requirements for small unmanned aircraft systems.

32 According to 14 CFR part 48, when would a small UA owner not be permitted to register it?

A. The owner is less than 13 years of age. [48.25 says, “(b) A small unmanned aircraft must be registered by its owner using the legal name of its owner, unless the owner is less than 13 years of age. If the owner is less than 13 years of age, then the small unmanned aircraft must be registered by a person who is at least 13 years of age.” Keep in mind that they are trying to make you know Part 48. There are other answers as to why a person could not register via Part 47 such as being a foreign citizen.]
B. All persons must register their small UA.
C. If the owner does not have a valid United States driver’s license. [Part 48 doesn’t require this and Part 47 doesn’t require it either.]

UA.I.B.K1 Registration requirements for small unmanned aircraft systems.

33 According to 14 CFR part 107, how may a remote pilot operate an unmanned aircraft in class C airspace?

A. The remote pilot must have prior authorization from the Air Traffic Control (ATC) facility having jurisdiction over that airspace. [You are going to have to have an airspace waiver. §107.41 says, “No person may operate a small unmanned aircraft in Class B, Class C, or Class D airspace or within the lateral boundaries of the surface area of Class E airspace designated for an airport unless that person has prior authorization from Air Traffic Control (ATC).” The FAA is handling those authorizations via a waiver process currently. Let me know if you need one! J]
B. The remote pilot must monitor the Air Traffic Control (ATC) frequency from launch to recovery. [This is the smart thing to do and maybe also required via the waiver, but it isn’t required per the regulations.]
C. The remote pilot must contact the Air Traffic Control (ATC) facility after launching the unmanned aircraft. [Um. The idea would be to call before launching, not after.]

UA.I.B.K16 Prior authorization required for operation in certain airspace.

34 According to 14 CFR part 107, what is required to operate a small UA within 30 minutes after official sunset?

A. Use of anti-collision lights. [§107.29(b) says, (b) No person may operate a small unmanned aircraft system during periods of civil twilight unless the small unmanned aircraft has lighted anti-collision lighting visible for at least 3 statute miles. The remote pilot in command may reduce the intensity of the anti-collision lighting if he or she determines that, because of operating conditions, it would be in the interest of safety to do so. (c) For purposes of paragraph (b) of this section, civil twilight refers to the following: (1) Except for Alaska, a period of time that begins 30 minutes before official sunrise and ends at official sunrise; (2) Except for Alaska, a period of time that begins at official sunset and ends 30 minutes after official sunset[.]”]
B. Must be operated in a rural area.
C. Use of a transponder.

UA.I.B.K9 Daylight operation.

35 You have received an outlook briefing from flight service through The briefing indicates you can expect a low-level temperature inversion with high relative humidity. What weather conditions would you expect?

A. Smooth air, poor visibility, fog, haze, or low clouds. [A temperature inversion means some warm air on top of some cold air. The cold air underneath on the ground, along with a high relative humidity, means you are expecting fog in the cooler area. You should also check the METARS for the airports in the area as you will most likely have a temperature/dewpoint spread that is low. Example 12/10. The air will be smooth because there is little convection.]
B. Light wind shear, poor visibility, haze, and light rain. [The cold air underneath means you are not going to have much convection so light wind shear is a wrong answer.]
C. Turbulent air, poor visibility, fog, low stratus type clouds, and showery precipitation. [Once again, you are going to have very little convection because of the cold air.]

UA.III.B.K1i Weather theory: Fog.

36 What effect does high density altitude have on the efficiency of a UA propeller?

A. Propeller efficiency is increased.
B. Propeller efficiency is decreased. [A high density altitude decreases the power output of a normal aspirated engine because there are less air molecules in the combustion. Most drones are electric so I’m taking this out of the equation. There are fewer air molecules flying over the wing (the propeller) which results in a decrease in lift.]
C. Density altitude does not affect propeller efficiency.

UA.III.B.K1a Weather theory: Density altitude.

37 What are characteristics of a moist, unstable air mass?

A. Turbulence and showery precipitation. [Cumuliform clouds, turbulent air, good visibility, and showery precipitation are all characteristics of unstable air.]
B. Poor visibility and smooth air. [Poor visibility and smooth air are characteristics of stable air.]
C. Haze and smoke. [Haze and smoke the causes of the poor visibility in stable air!]

UA.III.B.K1d Weather theory: Air masses and fronts.

38 What are the characteristics of stable air?

A. Good visibility and steady precipitation. [It would be poor visibility].
B. Poor visibility and steady precipitation. [Yes! stratiform clouds, smooth air, poor visibility in haze and smoke, and continuous precipitation.]
C. Poor visibility and intermittent precipitation. [No intermittentent is more like unstable air that creates cumulonimbus clouds]

UA.III.B.K1c Weather theory: Atmospheric stability, pressure, and temperature.

39 (Refer to FAA-CT-8080-2G, Figure 12.) The wind direction and velocity at KJFK is from

[SPECI KJFK 121853Z 18004KT 1/2SM FG R04/2200 OVC005 20/18 A3006]

A. 180° true at 4 knots. [This is how you remember if something is true or magnetic. “If it is in print, it must be true.” The only exceptions are for runways, VOR compass rose, and AWOS/ASOS headings when you call from a phone.]
B. 180° magnetic at 4 knots.
C. 040° true at 18 knots.

UA.III.A.K2 Aviation routine weather reports (METAR).

40 (Refer to FAA-CT-8080-2G, Figure 12.) What are the current conditions for Chicago Midway Airport (KMDW)?

[METAR KLAX 121852Z 25004KT 6SM BR SCT007 SCT250 16/15 A2991

SPECI KMDW 121856Z 32005KT 1 1/2SM RA OVC007 17/16 A2980 RMK RAB35]

A. Sky 700 feet overcast, visibility 1-1/2SM, rain. [Time, wind direction and speed, visibility in SM, clouds, Temperature/ dew point, altimeter in inches of mercury. It is almost always the same format. Just go through and find the two wrong answers.]
B. Sky 7000 feet overcast, visibility 1-1/2SM, heavy rain. [This can quickly be eliminated because it is always two zeros after the end for the altitude of the base of the clouds. It would be 700, not three zeros to make 7000.]
C. Sky 700 feet overcast, visibility 11, occasionally 2SM, with rain. [Clever. Really clever. Looking at the other material, like LAX above which shows 6SM, that should have clued you in that the value for that place should be a number in statute miles.]

Figure 20 area 2 of the Part 107 sample knowledge test questions

41. Refer to FAA-CT-8080-2G, Figure 20, area 2.) Why would the small flag at Lake Drummond of the sectional chart be important to a remote pilot?

A— This is a VFR check point for manned aircraft, and a higher volume of air traffic should be expected there.

B— This is a GPS check point that can be used by both manned and remote pilots for orientation.

C— This indicates that there will be a large obstruction depicted on the next printing of the chart.
