A remote pilot is hired to photograph damage near the top of a 700-ft radio tower. What is the highest altitude the small unmanned aircraft may legally reach during this inspection?

1,100 ft AGL, as long as the aircraft stays within a 400-ft radius of the tower

400 ft AGL, because the 400-ft ceiling has no exceptions

700 ft AGL, matching the exact height of the tower

800 ft AGL, which is twice the standard 400-ft limit

A new 4.2-lb quadcopter will be used for paid real estate photography. Which statement about registration and marking is correct?

The aircraft must be registered and the registration number must be readable on its exterior surface

Registration is optional because the aircraft weighs less than 5 lbs

The registration number may be kept inside a sealed battery compartment

Registration is required only if the aircraft is flown in controlled airspace

A remote pilot buzzes a group of hikers at low altitude to get a dramatic shot, startling several of them. Nobody is injured and the aircraft never touches anyone. How would the FAA most likely view this flight?

A careless or reckless operation that endangered the life or property of another

Acceptable, because no injury or property damage resulted

Acceptable, because artistic flights are exempt from operating rules

A violation only if the hikers file a written complaint

While filming a shoreline, a remote pilot spots a seaplane on final approach to the water roughly a half mile away and converging with the drone's flight path. What must the remote pilot do?

Yield the right of way and maneuver so the drone does not pass close to the seaplane

Hold altitude and heading so the seaplane pilot can predict the drone's path

Climb above the seaplane to keep it in sight during the pass

Descend to 50 ft AGL and hover until the seaplane lands

A remote pilot applicant is reviewing the vertical structure of the National Airspace System. Which statement correctly describes the vertical limits of Class A airspace?

It extends from 18,000 ft MSL up to and including FL600 over the contiguous states

It extends from the surface up to and including 10,000 ft MSL nationwide

It extends from 14,500 ft MSL up to but not including 18,000 ft MSL

It extends from 700 ft AGL up to but not including 18,000 ft MSL

A survey site falls inside an area outlined on the sectional with a blue hatched border and labeled R-2508. The chart panel lists the area as active during daylight hours with a using agency shown. What governs the planned Part 107 flight?

The flight may not enter the area unless permission of the controlling or using agency is obtained

The flight is allowed below 400 ft AGL because restricted areas apply only to manned aircraft

The flight is allowed as long as the aircraft remains at least 3 NM outside the boundary

The flight is allowed once LAANC authorization for the underlying airspace is approved

A METAR reads: KRDU 141753Z 21014G24KT 10SM FEW040 26/17 A3002. How should you interpret the wind group?

From 210 degrees magnetic at 24 knots, with lulls to 14 knots

From 240 degrees true at 21 knots, with gusts to 14 knots

Your sUAS has a maximum airspeed of 30 knots. You fly straight out directly into a steady 12-knot wind, then return on the reciprocal course. What are your groundspeeds?

18 knots outbound and 42 knots inbound

30 knots outbound and 30 knots inbound, since wind does not change groundspeed

42 knots outbound and 18 knots inbound

12 knots outbound and 30 knots inbound

A remote pilot decides to skip the preflight inspection, reasoning, 'This aircraft has flown 200 times without a single problem, so nothing will go wrong today.' Which hazardous attitude is this, and what is its antidote?

Invulnerability — 'It could happen to me.'

Impulsivity — 'Not so fast. Think first.'

Macho — 'Taking chances is foolish.'

Resignation — 'I'm not helpless. I can make a difference.'

1. Regulations
A remote pilot is hired to photograph damage near the top of a 700-ft radio tower. What is the highest altitude the small unmanned aircraft may legally reach during this inspection?
- a.400 ft AGL, because the 400-ft ceiling has no exceptions
- b.700 ft AGL, matching the exact height of the tower
- c.1,100 ft AGL, as long as the aircraft stays within a 400-ft radius of the tower
- d.800 ft AGL, which is twice the standard 400-ft limit
Answer: c
Explanation: Correct answer: 1,100 ft AGL. Under §107.51 the aircraft may fly higher than 400 ft AGL if it remains within a 400-ft radius of a structure and does not climb more than 400 ft above that structure's uppermost limit, so 700 + 400 = 1,100 ft. The 400-ft-only answer ignores the structure exception, and the 700-ft and 800-ft answers apply the wrong math to the rule.

2. Regulations
A new 4.2-lb quadcopter will be used for paid real estate photography. Which statement about registration and marking is correct?
- a.Registration is optional because the aircraft weighs less than 5 lbs
- b.The registration number may be kept inside a sealed battery compartment
- c.Registration is required only if the aircraft is flown in controlled airspace
- d.The aircraft must be registered and the registration number must be readable on its exterior surface
Answer: d
Explanation: Correct answer: the aircraft must be registered and marked so the registration number is legible on an exterior surface. Section 107.13 requires a small unmanned aircraft operated under Part 107 to be registered under Part 47 or Part 48, and the marking must be readable without tools or disassembly. Weight below 5 lbs, hiding the number inside a sealed compartment, and airspace class have no bearing on the requirement.

3. Regulations
A remote pilot buzzes a group of hikers at low altitude to get a dramatic shot, startling several of them. Nobody is injured and the aircraft never touches anyone. How would the FAA most likely view this flight?
- a.Acceptable, because no injury or property damage resulted
- b.Acceptable, because artistic flights are exempt from operating rules
- c.A violation only if the hikers file a written complaint
- d.A careless or reckless operation that endangered the life or property of another
Answer: d
Explanation: Correct answer: a careless or reckless operation. Section 107.23 prohibits operating a small unmanned aircraft system in a careless or reckless manner that endangers the life or property of another, and endangerment alone is enough without an actual injury. Artistic purpose is not an exemption, and enforcement does not depend on someone filing a complaint.

4. Regulations
While filming a shoreline, a remote pilot spots a seaplane on final approach to the water roughly a half mile away and converging with the drone's flight path. What must the remote pilot do?
- a.Hold altitude and heading so the seaplane pilot can predict the drone's path
- b.Climb above the seaplane to keep it in sight during the pass
- c.Yield the right of way and maneuver so the drone does not pass close to the seaplane
- d.Descend to 50 ft AGL and hover until the seaplane lands
Answer: c
Explanation: Correct answer: yield the right of way. Section 107.37 requires the small unmanned aircraft to give way to all aircraft, airborne vehicles, and launch or reentry vehicles, and prohibits operating so close to another aircraft as to create a collision hazard. Holding a predictable path or climbing toward the traffic does not satisfy that duty, and a fixed descent altitude is not what the rule requires.

5. Airspace & Charts
A remote pilot applicant is reviewing the vertical structure of the National Airspace System. Which statement correctly describes the vertical limits of Class A airspace?
- a.It extends from the surface up to and including 10,000 ft MSL nationwide
- b.It extends from 18,000 ft MSL up to and including FL600 over the contiguous states
- c.It extends from 14,500 ft MSL up to but not including 18,000 ft MSL
- d.It extends from 700 ft AGL up to but not including 18,000 ft MSL
Answer: b
Explanation: Class A airspace begins at 18,000 ft MSL and continues up to and including FL600, and every operation inside it is flown under instrument flight rules. The block from 14,500 ft MSL to 18,000 ft MSL is generally Class E, not Class A. The 700 ft AGL and surface figures describe Class E floors and surface areas, and no airspace class uses a nationwide 10,000 ft MSL ceiling.
6. Airspace & Charts
A survey site falls inside an area outlined on the sectional with a blue hatched border and labeled R-2508. The chart panel lists the area as active during daylight hours with a using agency shown. What governs the planned Part 107 flight?
- a.The flight is allowed below 400 ft AGL because restricted areas apply only to manned aircraft
- b.The flight is allowed as long as the aircraft remains at least 3 NM outside the boundary
- c.The flight may not enter the area unless permission of the controlling or using agency is obtained
- d.The flight is allowed once LAANC authorization for the underlying airspace is approved
Answer: c
Explanation: Section 107.45 forbids operating a small UAS in a prohibited or restricted area unless the remote pilot has permission from the using or controlling agency, and the R prefix identifies a restricted area. Restricted areas contain hazards such as artillery or guided missiles and apply to unmanned as well as manned aircraft, so low altitude does not exempt the flight. Staying outside the boundary would be legal, but the question places the site inside, and LAANC addresses controlled airspace rather than special use areas.

7. Weather
A METAR reads: KRDU 141753Z 21014G24KT 10SM FEW040 26/17 A3002. How should you interpret the wind group?
- a.From 140 degrees true at 21 knots, with gusts to 24 knots
- b.From 210 degrees true at 14 knots, with gusts to 24 knots
- c.From 210 degrees magnetic at 24 knots, with lulls to 14 knots
- d.From 240 degrees true at 21 knots, with gusts to 14 knots
Answer: b
Explanation: In a METAR wind group the first three digits are the direction the wind is blowing from, the next two are the sustained speed, and the digits after the G are the peak gust, so 21014G24KT is 210 degrees at 14 knots gusting 24 knots. METAR and TAF wind directions are referenced to true north, not magnetic north, which rules out the magnetic option. The other choices scramble the direction and speed digits or reverse the gust value, which is always higher than the sustained speed.
8. Weather
Your sUAS has a maximum airspeed of 30 knots. You fly straight out directly into a steady 12-knot wind, then return on the reciprocal course. What are your groundspeeds?
- a.30 knots outbound and 30 knots inbound, since wind does not change groundspeed
- b.42 knots outbound and 18 knots inbound
- c.18 knots outbound and 42 knots inbound
- d.12 knots outbound and 30 knots inbound
Answer: c
Explanation: Groundspeed is airspeed adjusted for wind, so flying into a 12-knot headwind gives 30 minus 12, or 18 knots, and returning with that wind as a tailwind gives 30 plus 12, or 42 knots. This is why the outbound leg eats far more battery per mile and why you should turn back well before the halfway point of your endurance. Wind clearly does affect groundspeed, and the reversed option applies the headwind on the wrong leg.
9. Loading & Performance
A quadcopter has an empty airframe weight of 6.8 lbs. You plan to fly it with two batteries weighing 1.9 lbs each and a gimbal camera weighing 1.4 lbs. The manufacturer lists a maximum takeoff weight of 13.2 lbs. How much additional payload may you add?
- a.0.6 lbs
- b.1.2 lbs
- c.2.6 lbs
- d.3.1 lbs
Answer: b
Explanation: Count every item that leaves the ground: 6.8 + 1.9 + 1.9 + 1.4 = 12.0 lbs, which leaves 13.2 - 12.0 = 1.2 lbs of margin. The 2.6 lbs answer comes from forgetting the camera, and 3.1 lbs comes from counting only one battery. 0.6 lbs would apply only if the loaded aircraft already weighed 12.6 lbs.
10. Operations & Safety
A remote pilot decides to skip the preflight inspection, reasoning, 'This aircraft has flown 200 times without a single problem, so nothing will go wrong today.' Which hazardous attitude is this, and what is its antidote?
- a.Invulnerability — 'It could happen to me.'
- b.Impulsivity — 'Not so fast. Think first.'
- c.Macho — 'Taking chances is foolish.'
- d.Resignation — 'I'm not helpless. I can make a difference.'
Answer: a
Explanation: Believing that trouble only happens to other people is the hazardous attitude of invulnerability, and its standard antidote is 'It could happen to me.' Impulsivity is acting before thinking, which is not the reasoning stated here. Macho is taking risks to prove ability, and resignation is feeling that outcomes are outside your control — neither matches a pilot who assumes the aircraft cannot fail.
