What's actually on it

CategoryApprox. weightWhat it really tests
Regulations15–25%Part 107 operating rules: altitude and speed limits, visual line of sight, waivers, accident reporting
Airspace & requirements15–25%Reading sectional charts, airspace classes, LAANC authorization. The section that fails people
Weather11–16%METARs/TAFs, density altitude, how weather affects small aircraft performance
Loading & performance7–11%Center of gravity, load factor in turns, battery and payload effects
Operations35–45%Crew resource management, emergency procedures, physiology, maintenance, night operations

The three things that fail first-time takers

  1. Sectional charts. Nothing in consumer drone flying prepares you for reading aviation charts. Expect several questions that hand you a chart excerpt and ask what airspace sits over a point. Drill these until they're boring.
  2. METAR/TAF decoding. Raw weather text like KAUS 121753Z 18011KT 10SM SCT025 BKN250 28/17 A3002 is on the test. Learn the format once and it's free points.
  3. Memorizing numbers loosely. 400 feet AGL, 100 mph groundspeed, 3 statute miles visibility, 500 feet below / 2,000 feet horizontal from clouds. The test loves swapping these in plausible wrong answers.

Part 107 FAQ

Do I need Part 107 to fly my drone at all?
Only for any flying that isn't purely recreational: real estate photos, inspections, YouTube monetization, anything for a business. Recreational flyers follow the separate TRUST rules instead.
How long should I study?
Most people with no aviation background pass comfortably after 15–25 hours of focused prep over 2–4 weeks. Existing pilots mostly need the drone-specific regulations.
What happens if I fail?
You wait 14 calendar days and pay the testing fee again, which is exactly why drilling to a green readiness score before booking beats "feeling ready."
Does the certificate expire?
The certificate itself doesn't expire, but you must complete free online recurrent training every 24 calendar months to keep flying under Part 107.

Drill it until test day is boring

The Part 107 app has hundreds of exam-style questions, a built-in METAR/TAF weather decoder, full timed simulations, and an AI tutor that knows the FARs.
