About this practice test

This set drills these topics: propeller inspection, airframe inspection, motor inspection, remote pilot responsibility for safe condition, maintenance schedule authority, battery visual inspection, battery damage and leakage, battery connector inspection, battery cycle tracking, firmware update verification, compass calibration, imu calibration, gps lock verification, failsafe setting verification, maintenance logkeeping, screw and fastener check, cable and wiring inspection, landing gear inspection, antenna inspection, gimbal and payload security, recording media readiness, preflight condition assessment, post-crash inspection, post-repair test flight, non-manufacturer parts and modifications, remote id preflight check, remote id broadcast module, electromagnetic interference and compass, takeoff and landing area assessment, battery storage maintenance, battery cell balance check, motor mount and arm lock check, propeller installation, control response check, operating environment risk assessment, debris and contamination check, battery connection security, firmware and app compatibility, compass calibration location, battery charge confirmation, structural deformation, payload attachment and interference, cooling and ventilation check, sensor and lens inspection, remote id failure action, reporting recurring defects, flight time tracking, spare parts readiness, preflight checklist use, aircraft storage condition, battery inspection before charging, motor rotation check, folding and transport reassembly, moisture and connector dryness, final go or no-go decision. Maintenance questions are fewer but easy to miss: there is no FAA-mandated inspection schedule for sUAS, so the manufacturer's instructions and the remote PIC's judgment rule.

When this set feels easy, switch to the Exam Simulator for a timed, no-feedback run at real test spec, or review with flashcards.

Frequently asked questions

How many questions are on the real Part 107 test?

The FAA Unmanned Aircraft – General (UAG) knowledge test has 60 multiple-choice questions with 3 options each. You get 2 hours at a PSI testing center, and the test fee is $175.

What score do I need to pass?

You need at least 70% correct — 42 of 60 questions — to pass the UAG knowledge test.

Are these the actual test questions?

No. These are original practice questions written from the same public FAA study material the real test covers: 14 CFR Part 107 and the FAA Remote Pilot – sUAS Study Guide (FAA-G-8082-22).
