FAA Unmanned Aircraft General - Small Knowledge Test Practice Test
The FAA Unmanned Aircraft General - Small Knowledge Test (UAG) covers aeronautical knowledge used to plan and conduct small unmanned aircraft operations under Part 107. Its subject matter includes operating limits, weather awareness, airport and airspace cues, aircraft instruments and systems, and decisions that help a remote pilot manage hazards during flight.
Exam overview
About the FAA Unmanned Aircraft General - Small Knowledge Test Exam
Remote pilots need to interpret conditions that affect a small UAS, including visibility, wind, pressure settings, and changing obstacles or nearby traffic. Operational judgment involves recognizing when a planned route or flight condition presents a hazard and choosing a safe response, such as adjusting the operation to maintain separation. Knowledge of aircraft systems supports sound handling of batteries and an understanding of how instruments such as pitot-static systems provide information. Airport cues such as a wind sock can help pilots assess local wind direction and strength. Part 107 operating concepts also include altitude limits and the minimum age for a remote pilot in command. Applying these concepts together helps pilots make informed preflight and in-flight decisions rather than treating operating rules, weather, and aircraft performance as separate concerns.
Sample Practice Questions
Review a selection from this exam's published US Practice Tests practice bank.
For a routine Part 107 operation, what is the general minimum flight visibility required from the control station?
Show answer
Correct answer: CPart 107 generally requires at least 3 statute miles of flight visibility from the control station. The rule also specifies cloud-clearance requirements.
Under Part 107, what is the minimum age to act as a remote pilot in command?
Show answer
Correct answer: BA person must be at least 16 years old to obtain a Remote Pilot Certificate with a small UAS rating and act as remote pilot in command under Part 107.
What does a wind sock primarily indicate at an airport or operating site?
Show answer
Correct answer: AA wind sock aligns with the wind to show its direction; its degree of extension gives a rough visual indication of wind strength.
Why should a remote pilot understand the manufacturer's battery charging instructions?
Show answer
Correct answer: ALithium-based batteries can be damaged or become hazardous if charged improperly. Following manufacturer limits and procedures helps reduce the risk of overheating, damage, or fire.
What is the usual effect of a higher-than-standard altimeter pressure setting on the indicated altitude, compared with using a lower setting at the same location?
Show answer
Correct answer: AWith a higher pressure setting, the altimeter generally indicates a higher altitude at the same physical location. Correct settings matter when interpreting pressure altitude and indicated altitude.
Unless an exception applies, what is the maximum altitude for a small UAS under Part 107 when measured from the surface?
Show answer
Correct answer: CPart 107 generally limits a small unmanned aircraft to 400 feet above ground level, subject to the rule's provision for operation within a 400-foot radius of a structure and remaining within 400 feet of its uppermost limit.
What does a pitot-static system primarily provide to an aircraft's instruments?
Show answer
Correct answer: AA pitot-static system uses ram air and static pressure inputs for instruments such as an airspeed indicator and, in a conventional arrangement, an altimeter and vertical-speed indicator. It does not measure weight or provide propulsion power.
How to use this practice test
The free UAG practice bank contains 50 published questions. A session presents up to 20 questions selected at random and shows results afterward. Use each session to check your understanding of topics such as weather interpretation, operating limits, aircraft systems, and hazard response; revisit missed concepts before another attempt.
Preparation tips
- Practice converting reported visibility, wind, and pressure information into decisions about whether conditions are suitable for a planned operation.
- Review Part 107 operating limits, including the general altitude limit and minimum age for a remote pilot in command, and note when an exception may apply.
- Study how pitot-static instruments obtain pressure information, and follow the aircraft manufacturer's battery charging and handling instructions.
- Use airport wind indicators such as a wind sock to assess local conditions, and plan how you would respond to birds, new obstacles, or other hazards in the flight path.
