What's on the Part 107 knowledge test

The Part 107 knowledge test, Unmanned Aircraft General – Small (UAG), has 60 scored multiple-choice questions plus 5 unscored ones.¹²³ You get 2 hours, and you need 70 percent to pass.¹² PSI’s bulletin puts 48 percent of the questions on regulations, so learn the Part 107 numbers first.²

New from October 26, 2026: current chart images

From October 26, 2026, the UAG test includes image-based questions that aren’t in the test supplements.⁹ The FAA says the images come from its latest charts, including Sectional Charts, and both of its UAG samples use Sectional excerpts.⁹

As of its September 2026 advisory, the FAA hadn’t set a date to remove supplements.⁹ Until it does, you keep access to the supplement for your test, FAA-CT-8080-2H.⁹¹

To prepare, practice on current Sectionals, which the FAA posts online as PDF and GeoTIFF files.¹⁰ The FAA calls its Aeronautical Chart Users’ Guide, effective July 9, 2026, a learning aid for new pilots.¹¹

What the test covers

The test follows the Remote Pilot ACS, FAA-S-ACS-10B, effective April 6, 2021.⁸³ The FAA encourages you to use the ACS as a reference while you prepare.³ The tasks below come from the ACS, and the shares come from PSI’s UAG bulletin, effective September 29, 2025.³²

ACS area	Share of questions and ACS tasks
Regulations (UA.I)	48% of questions. Tasks: General; operating rules; remote pilot certification; waivers; operations over people; Remote ID
Airspace Classification and Operating Requirements (UA.II)	20% of questions. Tasks: Airspace classification; airspace operational requirements
Weather (UA.III)	5% of questions. Tasks: Sources of weather; effects of weather on performance
Loading and Performance (UA.IV)	2% of questions. Tasks: Loading and performance
Operations (UA.V)	25% of questions. Tasks: Radio communications procedures; airport operations; emergency procedures; aeronautical decision-making; physiology; maintenance and inspection procedures

PSI based these shares on a job task analysis completed in 2025.² The FAA’s September 2026 advisory links this bulletin for UAG.⁹ The ACS, dated April 2021, prints different ranges, such as 35–45% for Operations, so go by PSI’s newer figures.³²

Practice each area with the StudyWren chapters that cover it:

StudyWren chapter	ACS area
1. Part 107 Basics: Applicability, Certification & Waivers	Regulations (UA.I)
2. Operating Rules: Remote PIC, Crew & Aircraft	Regulations (UA.I)
3. Operating Limitations, Night & Airspace Rules	Regulations (UA.I)
4. Operations Over People & Moving Vehicles	Regulations (UA.I)
5. Remote ID & Registration	Regulations (UA.I)
6. Airspace Classification & Flight Hazards	Airspace (UA.II)
7. Sectional Charts & Chart Supplement	Airspace (UA.II)
8. Weather Sources, Reports & Effects	Weather (UA.III)
9. Loading & Performance	Loading and Performance (UA.IV)
10. Radio Communications & Airport Operations	Operations (UA.V)
11. Emergency Procedures, Maintenance & Inspection	Operations (UA.V)
12. Decision-Making, CRM & Physiology	Operations (UA.V)

The key numbers to know

These limits come from 14 CFR Part 107 as the eCFR showed it in October 2026.

Rule	The number
Small unmanned aircraft	Less than 55 pounds on takeoff, including everything on board or attached12
Altitude	No higher than 400 feet above ground level, unless within a 400-foot radius of a structure and no more than 400 feet above the structure’s immediate uppermost limit13
Groundspeed	No more than 87 knots (100 miles per hour)13
Flight visibility	At least 3 statute miles, as seen from the control station13
Distance from clouds	At least 500 feet below and 2,000 feet horizontally13
Civil twilight and night	Lighted anti-collision lighting visible for at least 3 statute miles14
Visual line of sight	You, the person on the controls and any visual observer must be able to see it unaided (corrective lenses allowed). You and the person on the controls, or a visual observer, must watch it all flight.15
Controlled airspace	Prior ATC authorization for Class B, C or D airspace, or the surface area of Class E airspace designated for an airport16
Safety event report	Within 10 calendar days, for serious injury, loss of consciousness, or damage to other property above the $500 threshold17
Recency	Within the previous 24 calendar months, pass the initial test or complete recurrent training (Part 61 pilots with a current flight review have a training option)18
Retest	Not for 14 calendar days after a failure6

Outside Alaska, civil twilight is the 30 minutes before official sunrise and the 30 minutes after official sunset.¹⁴ To fly at night, you also need an initial test or training completed after April 6, 2021.¹⁴ You may dim the anti-collision lighting for safety, but you may not turn it off.¹⁴

The $500 threshold works two ways.¹⁷ You don’t report property damage if repair costs, including materials and labor, are $500 or less.¹⁷ You also don’t report it if the property is a total loss with a fair market value of $500 or less.¹⁷

AC 107-2A, the FAA’s guidance on Part 107, adds detail.¹⁹ A first-person view (FPV) device doesn’t satisfy visual line of sight, and binoculars may be used only momentarily.¹⁹ The AC treats a serious injury as Level 3 or higher on the Abbreviated Injury Scale, such as one needing hospitalization.¹⁹

The AC’s latest editorial update is dated May 26, 2022, and 107.9 was amended that December.²⁰¹⁷ Its section on 107.9 is still titled “Accident Reporting,” but the eCFR title is now “Safety event reporting.”¹⁹¹⁷ The AC also cites 107.5, which the eCFR now shows as reserved.¹⁹²¹

The AC says it doesn’t have the force and effect of law.¹⁹ When it and the eCFR differ, learn the eCFR wording.

Study materials

Start with these four FAA documents.

1. The ACS, FAA-S-ACS-10B. It lists each knowledge element with a code, such as UA.I.B.K10 for visual line of sight.³ Download the ACS from the FAA (PDF).³
2. AC 107-2A, Small Unmanned Aircraft System (Small UAS). Issued February 1, 2021, it replaced AC 107-2, and the FAA lists it as active.²⁰¹⁹ Download AC 107-2A from the FAA (PDF).¹⁹
3. The Remote Pilot – Small Unmanned Aircraft Systems Study Guide, FAA-G-8082-22. The FAA lists its publication date as August 18, 2016.²² Download the study guide from the FAA (PDF).²³
4. The testing supplement, FAA-CT-8080-2H. Its full title is Airman Knowledge Testing Supplement for Sport Pilot, Recreational Pilot, Remote Pilot, and Private Pilot, effective June 11, 2018.²⁴ Download FAA-CT-8080-2H from the FAA (PDF, about 176 MB).²⁵

The study guide predates three topics added to the UAG test on April 6, 2021: operations over people, Remote ID and night operations.²²²⁶ For those topics, the FAA’s testing notice lists the ACS, AC 107-2A and the Federal Register rules on operations over people and Remote ID.²⁶ It says the new questions on those two rules were drafted from the rules only.²⁶

The study guide’s knowledge list also stops at 12 areas.²³ Today’s 107.73 lists 13, and the extra one is operation at night.²⁷

The supplement’s preface lists UAG among the tests it’s for, and the test center supplies a copy.²⁵² The UAG test already includes some questions with the image embedded in the question, and those images can’t be previewed.⁹

PSI offers a free sample test under “Exam Resources” at faa.psiexams.com, in the Unmanned Aircraft Systems category.² You can also work through StudyWren’s free Part 107 practice questions.

Your results and retesting

The test center issues one copy of your Airman Knowledge Test Report (AKTR), and you can reprint it from your PSI account.² For UAG, the report lists ACS codes for the questions you missed.¹³ Look each code up in the ACS to see what to review.³

If you pass, the ACS says the report is valid for 24 calendar months when you apply for your certificate.³ If you fail, you can’t retest for 14 calendar days.⁶ Bring the failed AKTR to the test center, and you don’t need an instructor endorsement.¹

For scheduling, the fee, ID, applying for your certificate and recurrent training, see how to get a drone license.
