Part 107 Study Guide

Airspace Classifications and Rules

• Class B, C, D, E, G: Understand the hierarchy from most restrictive (Class B around major hubs) to least restrictive (Class G at low altitudes). Know which classes require ATC authorization for sUAS operations.
• Controlled vs. uncontrolled airspace: Controlled airspace (B, C, D, E) has defined dimensions and often requires authorization. Class G is uncontrolled and generally allows Part 107 operations without prior approval in many areas.
• Sectional charts: Learn to read VFR sectional charts — airspace boundaries, altitudes (MSL/AGL), airport symbols, and special use airspace (restricted, prohibited, MOA).
• LAANC: Low Altitude Authorization and Notification Capability provides near-instant authorization in controlled airspace up to published altitudes. Know when LAANC applies and how it differs from manual airspace authorizations.

Weather and Micrometeorology

• METAR and TAF: Decode aviation weather reports (METAR) and forecasts (TAF). Know wind, visibility, cloud layers, and precipitation codes. These are frequently tested.
• Cloud clearance and visibility: Part 107 requires 3 statute miles visibility and specific cloud clearance distances (500 feet below, 1,000 feet above, 2,000 feet horizontal in most cases). Memorize the exact values.
• Wind effects: Understand how wind affects sUAS stability, battery drain, and safe operations. Know when to postpone flights due to high winds.
• Density altitude: High temperature and elevation reduce air density, degrading propeller and motor performance. Know how to interpret density altitude and its impact on takeoff and climb.

FAA Regulations for Remote Pilots

• 14 CFR Part 107: The primary regulation governing small UAS operations. Study certificate requirements, pilot responsibilities, and operational limitations.
• Registration: sUAS between 0.55 and 55 pounds must be registered. Know the registration process, marking requirements, and when recreational vs. Part 107 rules apply.
• Waivers: Operations outside Part 107 limits (e.g., BVLOS, over people) require a waiver. Understand the waiver process and common waiver types.
• Certificate requirements: Age (16+), English proficiency, passing the knowledge test, and TSA security vetting. Know how to maintain currency (recurrent training every 24 months).

sUAS Operations

• Pre-flight inspection: Check aircraft, batteries, propellers, and control links before every flight. Document inspections when required.
• VLOS (Visual Line of Sight): You must maintain unaided visual contact with the aircraft. Understand exceptions and BVLOS waiver requirements.
• Right-of-way: sUAS must yield to manned aircraft. Know the order of priority: aircraft in distress, balloons, gliders, airships, airplanes/rotorcraft, then sUAS.
• Night operations: Part 107 allows night flights with anti-collision lighting visible for 3 statute miles and updated recurrent training. Know the 2021 rule changes.
• Emergency procedures: Lost link, low battery, and in-flight emergencies. Know when to declare an emergency and how to minimize risk to people and property.

Loading, Performance, and Weight & Balance

• Max takeoff weight: Part 107 applies to sUAS under 55 pounds at takeoff, including payload and accessories.
• Center of gravity (CG): Improper CG affects stability and control. Understand how payload placement and battery position affect CG.
• Density altitude effects: High density altitude reduces lift and motor efficiency. Know how to use performance charts and when to reduce payload or delay flights.
• Battery considerations: Cold reduces battery capacity; heat can damage cells. Plan for reserve power and safe return. Understand battery storage and transport rules.

Common Mistakes to Avoid

1. Memorizing without understanding: The exam tests application, not rote recall. Focus on why rules exist and how they apply in real scenarios.
2. Neglecting sectional charts: Chart reading is heavily tested. Practice identifying airspace, altitudes, and symbols until it becomes second nature.
3. Confusing MSL and AGL: Sectional chart altitudes are often MSL; Part 107 altitude limits (400 ft AGL) are AGL. Know when to convert and how.
4. Skipping METAR/TAF practice: Weather decoding appears on almost every exam. Use real METARs and TAFs to build fluency.
5. Underestimating regulations: Regulations carry the highest exam weight (25–30%). Spend adequate time on Part 107 text and related rules.
6. Ignoring weak areas: Track which topics you miss on practice tests and target those areas instead of only reviewing what you already know.
7. Not taking full mock exams: Simulate the real test with 60 questions under timed conditions to build stamina and time management.
8. Arriving unprepared on test day: Bring valid ID, know the testing center location, and get adequate rest. Small oversights can derail your attempt.
