According to Part 107, how may a remote pilot operate a small UA in Class C airspace?
- AAfter receiving prior authorization from ATC
- BBy monitoring the ATC frequency from launch to recovery
- CBy contacting the ATC facility after launching
Show answer
A. After receiving prior authorization from ATC
Operating in Class B, C or D airspace, or within the lateral boundaries of a Class E surface area designated for an airport, requires prior authorization from ATC.
Source: 14 CFR §107.41
In most areas of the United States, where does Class E airspace begin?
- AAt the surface
- BAt 1,200 feet AGL
- CAt 14,500 feet MSL
Show answer
B. At 1,200 feet AGL
In most areas the Class E base is 1,200 feet AGL; in many others it is the surface or 700 feet AGL. Where no lower base is charted, Class E begins at 14,500 feet MSL.

An alert area, charted as "A" followed by a number, informs pilots of
- Aa high volume of pilot training or an unusual type of aerial activity
- Bairspace where flight is prohibited
- Careas with live artillery firing
Show answer
A. a high volume of pilot training or an unusual type of aerial activity
Alert areas contain a high volume of pilot training or unusual aerial activity. Participating and transiting pilots are equally responsible for collision avoidance.

A stall occurs when the smooth airflow over an unmanned airplane's wing is disrupted and lift degenerates rapidly. This happens when the wing
- Aexceeds its maximum speed
- Bexceeds its critical angle of attack
- Cexceeds its maximum allowable weight
Show answer
B. exceeds its critical angle of attack
A stall is caused by exceeding the critical angle of attack. It can happen at any airspeed if a high enough angle of attack is imposed.

Which is a typical effect of operating an aircraft above its maximum weight?
- AA shorter takeoff run
- BA reduced rate of climb and a higher stalling speed
- CImproved maneuverability
Show answer
B. A reduced rate of climb and a higher stalling speed
Excess weight means a longer takeoff, reduced rate and angle of climb, lower maximum altitude, shorter range, reduced maneuverability and a higher stalling speed.

Your small UA releases a payload during flight. What should you anticipate?
- ANo change in handling
- BA change in weight that can shift the CG and affect balance
- CAn increase in stall speed
Show answer
B. A change in weight that can shift the CG and affect balance
Using expendable items or a jettisonable load changes weight during flight, which can shift the CG. Plan for how the CG will move and how the aircraft will respond.

What is a Common Traffic Advisory Frequency (CTAF)?
- AThe frequency used for airport advisory practices at an airport without an operating control tower
- BThe frequency of the nearest air route traffic control center
- CThe emergency frequency monitored by all aircraft
Show answer
A. The frequency used for airport advisory practices at an airport without an operating control tower
A CTAF carries airport advisory practices at airports without an operating tower. It may be a UNICOM, MULTICOM, FSS or tower frequency, and is identified on charts and in the Chart Supplement.

An aircraft reports that it is midfield left downwind for runway 13. Where is it relative to the runway?
- ANortheast of the runway
- BSouthwest of the runway
- CDirectly over the runway
Show answer
A. Northeast of the runway
Runway 13 points about 130° (southeast). Left traffic puts the downwind leg on the left of the landing direction, which is northeast of the runway, flown toward about 310°.

What is ATIS?
- AA continuous recording of local weather and other non-control information, usually updated hourly
- BThe frequency used to request ATC authorization for drones
- CAn automated system that tracks drone Remote ID
Show answer
A. A continuous recording of local weather and other non-control information, usually updated hourly
The Automated Terminal Information Service broadcasts weather, runways in use and other information in a loop. Each update gets a new code letter: Alpha, then Bravo, and so on.

Without a waiver, what is the maximum altitude at which a small unmanned aircraft may be flown under Part 107?
- A400 feet AGL, or higher if flown within a 400-foot radius of a structure and no more than 400 feet above the structure's uppermost limit
- B400 feet MSL, regardless of nearby structures
- C500 feet AGL, or 1,000 feet AGL over congested areas
Show answer
A. 400 feet AGL, or higher if flown within a 400-foot radius of a structure and no more than 400 feet above the structure's uppermost limit
Part 107 limits altitude to 400 feet above ground level. The one exception: within a 400-foot radius of a structure you may fly up to 400 feet above the structure's immediate uppermost limit.

Outside Alaska, which period counts as civil twilight for Part 107 operations?
- AFrom 1 hour before sunrise to 1 hour after sunset
- B30 minutes before official sunrise until sunrise, and from official sunset until 30 minutes after sunset
- CAny time the sun is less than 6 degrees above the horizon
Show answer
B. 30 minutes before official sunrise until sunrise, and from official sunset until 30 minutes after sunset
Except in Alaska, civil twilight is the 30 minutes before official sunrise and the 30 minutes after official sunset. Flying in civil twilight requires anti-collision lighting visible for 3 statute miles.

You move to a new permanent mailing address. How long can you keep exercising your remote pilot privileges without notifying the FAA?
- A30 days
- B60 days
- CUntil your certificate is renewed
Show answer
A. 30 days
After a change of permanent mailing address, you may not exercise the certificate's privileges beyond 30 days unless you have notified the FAA by letter or through the FAA website.

Which combination of conditions produces the highest density altitude?
- ALow elevation, high pressure, low temperature, low humidity
- BHigh elevation, low pressure, high temperature, high humidity
- CHigh elevation, high pressure, low temperature, low humidity
Show answer
B. High elevation, low pressure, high temperature, high humidity
High elevation, low pressure, high temperature and high humidity all reduce air density, which means a high density altitude and reduced performance.

What effect does high density altitude have on the efficiency of a small UA's propellers?
- APropeller efficiency increases
- BPropeller efficiency decreases
- CDensity altitude has no effect on propellers
Show answer
B. Propeller efficiency decreases
Thinner air gives the propellers less air to work with, so thrust, lift and overall performance decrease as density altitude rises.
