FAA Part 107 Exam: Weather-Related Questions

Importance of Weather Knowledge

• Weather-related questions are common in the FAA Part 107 exam.
• These questions are generally easier, providing an advantage if well-prepared.

Key Weather Questions for Exam Preparation

Question 1: Real-Time Weather Observations

• Options: TAF, METAR, SIGMET
• Correct Answer: METAR
  • Provides hourly weather updates with real-time data on wind, visibility, temperature, and precipitation.
  • TAF: Terminal Aerodrome Forecast – gives future weather conditions for the next 24-30 hours.
  • SIGMET: Focuses on hazardous weather like turbulence, not real-time data.

Question 2: Minimum Visibility for Drone Operations

• Correct Answer: 3 miles
  • Required to ensure pilots maintain line of sight and avoid hazards.

Question 3: Sudden Change in Wind Speed/Direction

• Options: Wind Shear, Gust Front, Microburst
• Correct Answer: Wind Shear
  • Rapid changes in wind speed or direction that destabilize drones.
  • Gust Front: Caused by thunderstorm outflows.
  • Microburst: A specific type of wind shear (localized downdrafts).

Question 4: Cloud Type Indicating Thunderstorms

• Options: Stratus, Cirrus, Cumulonimbus
• Correct Answer: Cumulonimbus
  • Associated with thunderstorms, lightning, and turbulence.

Question 5: Most Dangerous Condition for Drones

• Options: Light Rain, Freezing Rain, Drizzle
• Correct Answer: Freezing Rain
  • Coats drones with ice, affecting sensors and propellers.

Question 6: Front Bringing Thunderstorms

• Options: Cold Front, Warm Front, Stationary Front
• Correct Answer: Cold Front
  • Forces warm, moist air upward, creating unstable conditions.

Question 7: High Humidity's Effect on Drone Performance

• Options: Reduces Lift, Increases Lift, No Effect
• Correct Answer: Reduces Lift
  • Lowers air density, reducing propeller efficiency and stability.

Question 8: Aviation-Specific Forecast Tool

• Options: METAR, TAF, PIREP
• Correct Answer: TAF
  • Provides forecast specifically for aviation, covering conditions within 5 miles of an airport.

Question 9: Temperature Inversion

• Options: Cold air under warmer air, Warm air under cooler air, Rapid drop in temperature
• Correct Answer: Cold air trapped near the surface under warmer air
  • Creates stable air layers but can trap pollutants and reduce visibility.

Question 10: Most Hazardous Condition for Drones

• Options: Fog, Cross Winds, Thunderstorms
• Correct Answer: Thunderstorms
  • Combines wind shear, lightning, and turbulence.

Conclusion

• Reviewing these weather-related questions can help ease exam anxiety and improve performance.
• Understanding weather impacts on drone operations is crucial for safe and effective flying.
