ACS Area of Operation V

Part 107 operations and decision-making

The biggest share of the test: radio calls, airports, emergencies, aeronautical decision-making, physiology and maintenance, grouped the way the FAA's Airman Certification Standards group them.

Part 107, explained · Last reviewed October 25, 2026 against the FAA Airman Certification Standards. UAV Campus is not affiliated with the FAA.

What does the Part 107 test ask about operations?

Operations is the largest area of the 60-question test, at 35 to 45 percent. The FAA's Airman Certification Standards split it into six tasks: radio communications, airport operations, emergency procedures (including lithium batteries and lost control links), aeronautical decision-making, physiology, and maintenance and inspection.
