Part 107 Remote Pilot (UAG) practice questions with answers

Answer: A) Generally state and local laws

• ACorrect. The FAA focuses on safety.
• BIncorrect. Part 107 doesn't address privacy.
• CIncorrect. Privacy is mainly state and local law.
• DIncorrect. State and local laws apply.

Answer: B) The remote pilot certificate with a small UAS rating, and identification

Under 14 CFR 107.7(a)(1), the remote PIC must have the remote pilot certificate with a small UAS rating and identification in physical possession and readily accessible, and must present them when asked.

• AIncorrect. Part 107 does not require an FAA medical certificate.
• BCorrect. 107.7(a)(1) requires the certificate with a small UAS rating and identification to be in physical possession and readily accessible. The certificate must also be presented when the FAA, NTSB, TSA, or law enforcement asks for it.
• CIncorrect. Part 107 operations require a remote pilot certificate with a small UAS rating, not a private pilot certificate.
• DIncorrect. Part 107 has no 90-day flight-time logbook requirement. Recency is met through the aeronautical knowledge requirements of 107.65.

Answer: A) Yes; they may regulate land use such as takeoff sites

• ACorrect. Check local ordinances.
• BIncorrect. Land use rules are local.
• CIncorrect. Local land use rules can apply to all.
• DIncorrect. Local land use rules can apply broadly.

Answer: C) The highest terrain or obstacle in the quadrangle is covered by 3,500 feet MSL

The Maximum Elevation Figure, printed in thousands and hundreds of feet MSL, shows the highest known elevation in the quadrangle, including terrain and vertical obstacles. 3⁵ means 3,500 feet MSL.

• AIncorrect. MEFs are given in feet above mean sea level (MSL), not above ground level (AGL).
• BIncorrect. The MEF is for situational awareness about terrain and obstacles. It does not set a required minimum flight altitude.
• CCorrect. The MEF shows, in thousands and hundreds of feet MSL, an elevation that covers the highest known terrain and vertical obstacles (towers, trees, etc.) in the quadrangle.
• DIncorrect. The MEF has nothing to do with airspace floors. Class E floors are shown by vignettes, shaded lines, and altitude labels, not by the quadrangle MEF.

Answer: C) Not fly inside the TFR

• AIncorrect. The TFR still applies.
• BIncorrect. The TFR still applies.
• CCorrect. VIP TFRs prohibit unauthorized flights, including drones.
• DIncorrect. The TFR still applies.

Answer: C) 18,000 feet MSL

• AIncorrect. Class A starts higher.
• BIncorrect. That is the Part 107 limit.
• CCorrect. Class A begins at 18,000 feet MSL.
• DIncorrect. That is a Class E floor.

Answer: A) A sudden, drastic change in wind speed and/or direction over a very small area

Wind shear is a sudden, drastic change in wind speed and/or direction over a very small area. It can happen at any altitude and can push a small UA off course or cause a sudden loss of altitude.

• ACorrect. The FAA defines wind shear as a sudden, drastic change in wind speed and/or direction over a very small area. It can happen at any altitude and can cause loss of control or a sudden loss of altitude.
• BIncorrect. This describes wake turbulence, which aircraft generate. It is not a weather phenomenon.
• CIncorrect. This describes a thermal (convective current). It can cause bumpy air, but it is not the definition of wind shear.
• DIncorrect. This is the temperature/dew point spread, which is used to predict fog and clouds. It has nothing to do with changes in wind.

Answer: B) Advection fog

• AIncorrect. Radiation fog forms on calm, clear nights.
• BCorrect. Advection fog forms as moist air is carried over a colder surface by the wind.
• CIncorrect. Steam fog forms over warmer water.
• DIncorrect. Ice fog forms in very cold air.

Answer: A) The sudden drop in weight and shift in CG can make the aircraft climb abruptly or become unstable

Releasing a heavy payload suddenly changes both the aircraft's weight and its CG. The aircraft may climb abruptly or become unstable, so the remote PIC should plan for this effect before the drop.

• ACorrect. Releasing a load removes weight all at once and can shift the CG. With thrust still set for the heavier weight, the aircraft may balloon upward or pitch and roll until the pilot or flight controller compensates.
• BIncorrect. CG depends on how all of the weight is distributed, including payload. The FAA notes that the CG can shift when load items are shifted or expended.
• CIncorrect. Density altitude depends on atmospheric conditions such as elevation, pressure, temperature and humidity, not on aircraft weight.
• DIncorrect. Removing weight does not reduce rotor thrust. With the same thrust and less weight, the aircraft tends to climb, not sink.

Answer: A) Oscar

• ACorrect. It's standard ICAO phonetics.
• BIncorrect. That's an older alphabet.
• CIncorrect. It's Oscar.
• DIncorrect. It's Oscar.

Answer: A) Downwind

• ACorrect. The downwind leg runs parallel to the runway in the opposite direction of landing.
• BIncorrect. Final is aligned with the runway for landing.
• CIncorrect. Base is perpendicular to the runway.
• DIncorrect. Crosswind is perpendicular after takeoff.

Answer: A) The tablet may overheat and dim or shut down mid-flight

Tablets and phones used as control displays can overheat and dim or shut down in direct sun. Shade them and monitor their temperature so the control station stays in a condition for safe operation.

• ACorrect. Consumer tablets and phones can thermally throttle, dim or shut down in heat and direct sun, and the pilot loses telemetry and the video feed. Shade the device and watch its temperature so the system stays in a condition for safe operation (14 CFR 107.15).
• BIncorrect. The aircraft's GPS receiver is on the aircraft. A warm tablet on the ground does not affect its satellite reception.
• CIncorrect. Altitude comes from the aircraft's own sensors and is sent to the display. Heating the tablet does not bias that data; the real risk is the display failing.
• DIncorrect. Heat does not improve radio performance. Overheated electronics are more likely to degrade or fail.

Answer: C) Ahead and to the right

• AIncorrect. That is 10 or 11 o'clock.
• BIncorrect. That is 6 o'clock.
• CCorrect. 2 o'clock is about 60 degrees to the right of straight ahead.
• DIncorrect. Clock positions are horizontal.

Answer: A) The control link is lost or the pilot cannot control the aircraft, so it no longer flies in a predictable or planned manner

A flyaway is when the control link is lost or the pilot cannot control the aircraft, so it no longer operates in a predictable or planned manner. A lost-link event in which the aircraft follows its programmed procedure is not a flyaway.

• ACorrect. The FAA defines a flyaway as an interruption or loss of the control link, or the pilot being unable to control the aircraft, with the result that it is not operating in a predictable or planned manner.
• BIncorrect. This is a lost link: the aircraft is still behaving in a predictable, planned way. FAA guidance states that lost link is not considered a flyaway.
• CIncorrect. The pilot still has control and the aircraft responds to inputs, so this is not a flyaway.
• DIncorrect. The aircraft stays under the pilot's control and behaves predictably, so it does not meet the definition of a flyaway.

Answer: A) An open patch of ground well away from vehicles, rebar-reinforced concrete, and metal structures

Calibrate the compass in an open area away from metal, reinforced concrete, vehicles, and other magnetic sources. Interference can give a faulty heading reference, and the aircraft is then not in a condition for safe operation.

• ACorrect. A magnetometer calibrated away from ferrous metal and magnetic fields gets a clean reference. That supports the preflight check that the sUAS is in a condition for safe operation.
• BIncorrect. Being level doesn't help here. The steel rebar inside reinforced concrete can distort the magnetic field and corrupt the calibration.
• CIncorrect. The vehicle's steel body and electrical systems create magnetic interference that can produce a bad heading reference.
• DIncorrect. Having gear close by is convenient, but a metal case and batteries near the aircraft can disturb the compass during calibration.
