FAA 107 Weather Effects & Flight Planning 5

Question 1

What weather product provides continuous weather radar data most useful for identifying precipitation near a planned drone flight area?

Accepted Answer

NEXRAD radar imagery via apps like ForeFlight or AirMap

Answer

NEXRAD radar imagery, available through aviation apps, provides near-real-time precipitation data to identify rain, hail, and storm cells near planned flight areas.

Question 2

A drone pilot notices their aircraft is drifting consistently in one direction despite a hover command. What does this indicate?

Accepted Answer

A persistent crosswind affecting the drone's position

Answer

Consistent drift in one direction during hover indicates a persistent crosswind that the drone's flight controller is compensating for, or occasionally failing to fully compensate for.

Question 3

What is the maximum wind speed generally considered safe for most consumer and commercial drones per manufacturer guidelines?

Accepted Answer

20-25 mph (17-22 knots)

Answer

Most consumer and commercial drones have rated wind resistance of approximately 20-25 mph; exceeding this risks loss of control, though pilots should always check their specific aircraft's manual.

Question 4

Which surface is most likely to produce thermal updrafts that could affect low-altitude drone operations on a hot sunny day?

Accepted Answer

Dark asphalt parking lots or rooftops

Answer

Dark asphalt and rooftops absorb solar radiation rapidly and produce strong thermal updrafts as heated air rises, creating turbulence hazardous to low-altitude drone operations.

Question 5

What does 'VFR not recommended' in a standard weather briefing mean for a drone pilot operating in uncontrolled airspace?

Accepted Answer

Current or forecast weather is below VFR minimums, making visual flight unsafe though not always illegal

Answer

'VFR not recommended' means a briefer believes weather is or will be below VFR minimums in the area, advising caution even if a pilot believes they can maintain VFR.
