Part 107 FAQ
The questions people actually ask about the Part 107 knowledge test, answered from FAA and PSI source documents — not guessed.
About This Site
Is this Part 107 practice test actually free, and do I need an account?
Yes. All 270 practice questions, the five ACS-area drills, both chart drills, and the full 60-question mock exam are free, with no signup and no account required.
Can I prepare for the Part 107 test for free?
Yes. The FAA publishes its own free study materials — the Remote Pilot Study Guide, the Airman Certification Standards, and sample test questions — and every practice question, guide, and mock exam on this site is free as well, with nothing to buy.
How many Part 107 practice questions are on this site?
270 verified questions across all five FAA knowledge-test areas, covering 128 of the FAA's 131 knowledge-test codes, weighted toward Regulations and Airspace to match their real share of the exam.
Does this practice test cover the new sectional chart questions?
Yes. 68 questions are built around real FAA chart figures, including the sectional-chart drill for the image-based questions the FAA added to the test on October 26, 2026.
Is this an official FAA practice test?
No. This site is independently run and not affiliated with the FAA. Every question cites a public FAA source document and page so you can verify it yourself.
How is this different from other Part 107 practice tests?
Every question shows its ACS code and the exact source page it came from, and both wrong answers are explained, not just the right one — most practice sites explain only the correct answer.
What is the best free way to study for the Part 107 test?
Read a study guide for each topic, then drill real questions by ACS area in order of exam weight — Regulations first, then Airspace, Operations, Weather, and Loading & Performance — practice sectional charts, and finish with a full mock exam under real time pressure. That order mirrors how the FAA actually weights the test, so your study time matches the exam.
Mock Exam
Is the FAA Part 107 practice test free, and how close is it to the real test?
This mock exam is free and matches the real UAG test's format exactly: 60 scored questions, 120 minutes, and a 70% passing score. It is not an official FAA test, and it is not affiliated with the FAA — it is built from this site's own verified question bank.
Does the mock exam match the FAA's current area weighting?
Yes. The 60 questions are drawn weighted to the current specification effective September 29, 2025 — 48% Regulations, 20% Airspace, 5% Weather, 2% Loading & Performance, 25% Operations — not the older FAA-S-ACS-10B blueprint ranges the FAA itself retired the same date.
What happens if I run out of time on the mock exam?
The exam auto-submits and scores whatever you've answered so far — unanswered questions count as wrong, the same way an unfinished real exam would be scored. Your progress is saved on this device, so you can resume a session after a reload as long as the timer hasn't expired.
Sectional Charts
How much of the Part 107 test is sectional chart questions?
Most chart-reading questions fall under Airspace Classification and Operating Requirements, which is 20% of the current exam specification, though a few chart-dependent questions also appear in Weather and Loading & Performance. There's no separate "charts" line item in the FAA's own breakdown.
What's the difference between the testing supplement figures and current sectional charts?
The testing supplement (FAA-CT-8080-2H) is a fixed set of figures printed in a book issued at the test center, unchanged since 2018. Since October 26, 2026, some test questions instead embed images taken directly from current, regularly-updated FAA VFR sectional charts — a different and larger set of material to be able to read.
Do I need to buy real aeronautical charts to study?
No. FAA aeronautical charts are public domain and free to download from the FAA's own digital products page, and this site's chart drills use real excerpts from current sectionals for the same reason.
What do the colored lines on a sectional chart mean?
They mark the floor and class of controlled airspace: solid blue for Class B, solid magenta for Class C, dashed blue for Class D, and dashed or fading magenta/blue for Class E, depending on its floor (FAA-CT-8080-2H, Legend 1, p. 1-1).
Are these the same chart figures used on the real exam?
These figures come from FAA-CT-8080-2H, the Airman Knowledge Testing Supplement issued at the test center. Starting October 26, 2026, the exam also draws separate image-based questions directly from current VFR sectional charts (September_2026_Special_Edition.pdf, p. 6).
Is the obstacle height number measured from the ground or from sea level?
Both appear together: the plain number is height above mean sea level, and the number in parentheses underneath is height above ground level (FAA-CT-8080-2H, Legend 1, p. 1-1).
Do I need ATC authorization everywhere inside a magenta or blue ring?
Not always — it depends on the floor charted for that segment. The same Class C ring can require authorization at the surface in one spot and not at all 300 ft. AGL a few miles away, if the floor there is charted at 1,200 ft. MSL instead of the surface (sport_rec_private_akts.pdf, Figure 20, p. 2-19; 14-cfr-107.txt, § 107.41).
Free PDFs & the Printable Test
Is there a free FAA Part 107 study guide PDF?
Yes. The FAA publishes the Remote Pilot – sUAS Study Guide (FAA-G-8082-22) as a free PDF, along with the Airman Certification Standards and sample test questions — all linked from this page straight to faa.gov, with no copies hosted here.
Where can I get the Part 107 rules as a PDF?
14 CFR Part 107 is published on eCFR, which includes a print-friendly view you can save as a PDF from your browser's print function; the FAA's Advisory Circular AC 107-2A, which explains those rules in plain language, is already a free PDF on faa.gov.
Is there a Part 107 practice test with answers in PDF?
Yes — this site's printable practice test includes a full answer key with explanations and ACS codes you can save as a PDF. The FAA also publishes its own free UAG sample questions as a PDF, but that document does not include an answer key.
The Test
What is the current Part 107 exam weighting?
Regulations 48%, Airspace 20%, Weather 5%, Loading & Performance 2%, Operations 25%, effective September 29, 2025 (UAG_Information_Bulletin.pdf, p. 4).
Why do some sites show different percentages, like Operations at 35–45%?
Those sites are quoting the FAA-S-ACS-10B Knowledge Test Blueprint appendix, which the FAA declared obsolete effective 2025-09-29 (community_advisory_August_2025.pdf, p. 3). The PSI UAG Applicant Information Bulletin is the current authority.
Did the test questions themselves change, or just the weighting?
Just the weighting. The same advisory states the UAG test topics and subject matter did not change, and there was no reduction in test time allotment (community_advisory_August_2025.pdf, p. 3).
How many questions are on the Part 107 test, and how long is it?
60 scored questions plus 5 unscored validation questions — 65 total, though you can't tell which 5 are unscored — in 120 minutes (UAG_Information_Bulletin.pdf, p. 4).
Is the Part 107 knowledge test multiple choice?
Yes. The test consists of objective, multiple-choice questions, each with a single correct response, and you select the one best answer of those presented (UAG_Information_Bulletin.pdf, p. 4; uas_acs.pdf, p. 13).
How hard is the Part 107 test, and how long should I study?
The FAA doesn't publish a pass rate or a recommended study timeline for this exam, so we won't invent either. What is published: Regulations (48%) and Operations (25%) carry nearly three-quarters of the questions, so that's where study time pays off most — and a full mock exam under real time pressure is a more reliable gauge of your own readiness than a generic number of hours.
Taking the Test
What score do I need to pass the Part 107 knowledge test?
70% correct — 42 of the 60 scored questions, so you can miss up to 18 (UAG_Information_Bulletin.pdf, p. 4).
Do the 5 unscored questions count toward my score?
No — they're validation questions the FAA uses to test new content, but you can't tell which ones they are, so answer every question as if it counts (UAG_Information_Bulletin.pdf, p. 4).
What does the test report show if I fail?
Your Airman Knowledge Test Report (AKTR) lists the specific ACS knowledge codes for the task elements you were weak on, so you know exactly what to restudy (uas_acs.pdf, Appendix 3, p. A-5).
What happens if I fail the Part 107 test, and how long until I can retake it?
A 14-day waiting period before you can retest, with no instructor endorsement required — you just bring your failed AKTR to the test center (UAG_Information_Bulletin.pdf, p. 4).
What ID do I need to take the Part 107 knowledge test?
Valid, current identification showing a photo, date of birth, signature, and physical residential address — a driver's license, passport, or government/military ID for U.S. citizens (UAG_Information_Bulletin.pdf, p. 2).
What does the test center provide, and can I bring my own calculator?
The test center supplies the required supplement book, scratch paper, and a writing instrument, and PSI's own testing software has a built-in four-function calculator. You may also bring your own basic add/subtract/multiply/divide calculator with no permanent memory storage — you'll reset it in front of the proctor (UAG_Information_Bulletin.pdf, p. 5).
Are phones and watches allowed in the testing room?
No — both are prohibited, along with recording devices, reference material, and several other personal items (UAG_Information_Bulletin.pdf, p. 5).
Where do I take the test, and can I take it online?
In person, at one of PSI's FAA-approved testing centers — the knowledge test itself isn't offered online. Scheduling is done online, 24 hours a day, at faa.psiexams.com (UAG_Information_Bulletin.pdf, p. 2).
How much does the Part 107 test cost?
The PSI bulletin that governs scheduling and test-day procedure doesn't list a fee, and the fee can change independently of that bulletin, so confirm the current price directly with PSI when you schedule at faa.psiexams.com.
Getting Your Certificate
What is a Part 107 drone license?
There's no document literally called a "drone license." The official credential is a Remote Pilot Certificate with a small UAS rating, issued by the FAA under 14 CFR part 107 after you pass the UAG knowledge test and complete the application process.
How do I get my Part 107 drone license?
Establish an FTN in IACRA, pass the UAG knowledge test at a PSI testing center, then apply for FAA Form 8710-13 online through IACRA using your test's Exam ID — the online path is strongly preferred, since it's the only one that produces a temporary certificate while TSA vetting completes. The full process is covered step by step below.
How old do I need to be to get a Part 107 Remote Pilot Certificate?
At least 16 years old, per 14 CFR § 107.61, along with being able to read, speak, write, and understand English and having no physical or mental condition that would interfere with safely operating a small UAS.
What is an FTN and do I need one before the test?
An FAA Tracking Number, established in IACRA at iacra.faa.gov/iacra before you can take any FAA airman knowledge test — required since January 13, 2020 (AC_107-2A.pdf, § 6.6).
Does the TSA have to clear me before I get a certificate?
Yes — the TSA vets every applicant before a temporary Remote Pilot Certificate is issued. A successful vetting leads to a permanent certificate; an unsuccessful one disqualifies the applicant, who may appeal to the TSA (AC_107-2A.pdf, § 6.5).
Recurrent Training
Is there still a Part 107 recurrent knowledge test?
No — the Unmanned Aircraft Recurrent (UGR) knowledge test was discontinued April 6, 2021 and replaced by free online recurrent training (uas_testing_information.pdf, p. 1).
How long does my Part 107 certificate last, and how often is recurrent training required?
The certificate itself doesn't expire, but exercising it requires recurrent training within 24 calendar months of your initial knowledge test and every 24 calendar months after that (AC_107-2A.pdf, § 6.7.2, p. 6-5).
Does recurrent training cost anything?
No — it's completed free online through the FAA Safety Team at faasafety.gov (uas_testing_information.pdf, p. 1).
What happens if I complete recurrent training late?
You may not exercise your Remote Pilot Certificate privileges during the gap between the due date and when you finish — and your next deadline then counts 24 months from your completion date, not the original due date (AC_107-2A.pdf, Figure 6-1, p. 6-6).
The FAA's Most-Missed Topic
What's the most-missed topic on the Part 107 exam?
Declaration of Compliance (ACS code UA.I.E.K13) — the only UAG knowledge code the FAA's own quarterly report lists above a 70% miss rate, at 78.58% in the 2nd Quarter CY25 report (frequently_missed_acs_codes_fy_2025_2q.pdf, p. 1).
Is this based on real FAA data, or this site's own quiz results?
Real FAA data. It's the FAA Safety Analysis Branch's quarterly Frequently Missed Knowledge Test ACS Codes report, based on SPAS data from every scored knowledge test administered nationwide — not telemetry from this or any other practice site.
Is the miss rate for this topic getting better or worse?
Worse. The prior report (2nd Quarter CY24) showed 75.87% missed; the current report (2nd Quarter CY25) shows 78.58% — a rise of about 2.7 percentage points year over year.
Why does one hard ACS code matter so much for exam prep?
Because it sits in ACS Area I (Regulations), which is 48% of the current Part 107 exam — the single largest content area. A code the FAA flags as hardest-missed, inside the block worth the most points, is a high-leverage place to study.
The October 2026 Chart Change
Do I need to memorize the exact chart images that will be on my test?
No — the FAA is explicit that once an image is used in a live question it is never published or previewable (September_2026_Special_Edition.pdf, p. 6). The skill being tested is reading any current chart, not recognizing a specific picture.
Is the printed testing supplement being discontinued?
Not yet, and no removal date has been set. Candidates keep using the supplement at the test center until the FAA announces otherwise, with advance notice (August_2026_ATCA.pdf, p. 5).
What part of the exam do these new chart questions count toward?
Airspace Classification and Operating Requirements (ACS Area II), which is 20% of the current UAG test specification (UAG_Information_Bulletin.pdf, p. 4) — not the 15–25% older study material still quotes from the retired ACS blueprint.
Are Millville and Grand Canyon the actual questions I'll get?
No — those are the two sample questions the FAA chose to publish alongside the announcement (September_2026_Special_Edition.pdf, pp. 9–10). They show the format and difficulty, not the live question pool.
Regulations
What is the maximum altitude for a part 107 drone flight?
400 feet above ground level, unless you're within 400 feet of a structure — then you may fly up to 400 feet above that structure's uppermost point (14-cfr-107.txt, § 107.51(b)).
Do I need a waiver to fly at night under part 107?
No. Since April 6, 2021, night operations are allowed without a waiver as long as the remote PIC has completed training covering night operations and the aircraft has anti-collision lighting visible for at least 3 statute miles (14-cfr-107.txt, § 107.29).
How many part 107 regulations can the FAA waive?
Ten, listed in 14 CFR § 107.205 — covering things like moving-vehicle operation, visual line of sight, visual observer use, and the § 107.51 operating limitations. Registration and certification requirements cannot be waived at all.
How long do I have to wait to retake the knowledge test after failing?
14 calendar days from the date of the failed attempt (14-cfr-107.txt, § 107.71).
Do I need to register my drone under Part 107?
Yes. Operating a civil small UAS under part 107 requires complying with the aircraft-registration provisions in 14 CFR § 91.203(a)(2), which means carrying a valid Certificate of Aircraft Registration issued under part 47 or 48 (14-cfr-107.txt, § 107.13).
Airspace
Which airspace classes require ATC authorization to fly a drone?
Class B, C, and D, plus the surface area of Class E airspace designated for an airport. Outside those — the rest of Class E, and all of Class G — no ATC authorization is required (14-cfr-107.txt, § 107.41).
Do I need authorization to fly in Class G airspace?
No. Class G is uncontrolled airspace, and § 107.41 only requires ATC authorization for Class B, C, D, and Class E surface areas (14-cfr-107.txt, § 107.41).
What's the difference between a restricted area and a military operations area (MOA)?
A restricted area (charted "R" plus a number) involves hazards like artillery or guided missiles, and penetrating it without permission from the controlling agency can be dangerous. An MOA separates military training activity from IFR traffic, and non-participating IFR aircraft can still be cleared through one if ATC can provide separation (remote_pilot_study_guide.pdf, pp. 6–7).
How do I find out if there is a temporary flight restriction (TFR) where I want to fly?
TFRs are issued by FDC NOTAM, so checking NOTAMs for your planned area and time before every flight is how you catch one (remote_pilot_study_guide.pdf, pp. 9–10; AC_107-2A.pdf, para. 5.10.3).
Operations Over People
Do all four categories of operations over people require a Declaration of Compliance?
No. Only Category 2 and Category 3 aircraft need one. Category 1 qualifies by weight alone (0.55 lb. or less), and Category 4 substitutes a part 21 airworthiness certificate — neither needs a DoC (14-cfr-107.txt, §§ 107.110, 107.140).
Is there a minimum distance I must keep from a person under part 107?
No specific number. Part 107 requires the remote pilot to use judgment — weighing the aircraft's performance, environment, and failure modes — rather than following a fixed stand-off distance (AC_107-2A.txt, § 8.3.1).
What's the difference between a Means of Compliance and a Declaration of Compliance?
A Means of Compliance (MoC) is the test/analysis/inspection method that proves an aircraft design meets the injury-energy standard. A Declaration of Compliance (DoC) is the filing that certifies a specific aircraft meets that standard using an accepted MoC (14-cfr-107.txt, §§ 107.155, 107.160).
If I modify my drone, do I need to file my own Declaration of Compliance?
Only if the modification isn't on the list of allowed modifications in the manufacturer's remote pilot operating instructions. In that case you become the 'applicant' and must requalify the modified aircraft and file a new DoC before flying it over people again (AC_107-2A.txt, §§ 8.4.4–8.4.5).
Loading & Performance
Does load factor increase stalling speed in direct proportion?
No — stalling speed increases with the square root of load factor. A 50-knot aircraft under a 2.000 G load factor (a 60° bank) stalls around 50 × √2.000 ≈ 71 knots, not 100 knots (remote_pilot_study_guide.pdf, p. 32; sport_rec_private_akts.pdf, Figure 2, p. 2-2).
Can a small UA actually reach a 90° banked, constant-altitude turn?
No. Load factor rises toward infinity as bank angle approaches 90°, so a 90° banked turn at constant altitude is not mathematically possible (remote_pilot_study_guide.pdf, p. 32).
What's the first step in using the density altitude chart?
Convert field elevation to pressure altitude using the chart's altimeter-setting conversion table (pressure altitude = field elevation + conversion factor), then combine that pressure altitude with outside air temperature on the main graph (sport_rec_private_akts.pdf, Figure 8, p. 2-8).
What preflight battery findings indicate a possible impending failure?
A distorted or bulging battery casing, and diminishing flight time capability on an electric-powered aircraft — both can signal a battery no longer reliable as a power source, with a risk of fire or extreme heat (AC_107-2A.pdf, Table C-1, p. C-3).
Operations
What does CTAF stand for?
Common Traffic Advisory Frequency — the frequency designated for airport advisory practices at an airport without an operating control tower. It may be a UNICOM, MULTICOM, FSS, or tower frequency (remote_pilot_study_guide.pdf, p. 40).
What are the five hazardous attitudes in aeronautical decision-making?
Anti-authority, impulsivity, invulnerability, macho, and resignation — each with its own memorized antidote, such as "Not so fast. Think first." for impulsivity (faa-h-8083-25c.pdf, Ch. 2, p. 2-5).
How much water should a remote pilot drink to prevent dehydration?
Two to four quarts every 24 hours. Dehydration's first noticeable effect is fatigue, and heat or high altitude increase the rate of water loss (remote_pilot_study_guide.pdf, p. 47).
Who is responsible for a small UAS preflight inspection?
The remote pilot in command, who must ensure the aircraft is in a condition for safe operation before every flight (14-cfr-107.txt, § 107.49).
Weather
Is the wind direction in a METAR true or magnetic?
True. A METAR wind group gives direction in tens of degrees true, not magnetic, followed by speed in knots and a "G" for the peak gust (remote_pilot_study_guide.pdf, p. 16).
What's the difference between a METAR and a SPECI?
A METAR is the routine, regularly-scheduled report. A SPECI is an unscheduled special report that can be issued any time between routine METARs to capture a rapid weather change (remote_pilot_study_guide.pdf, p. 16).
What does TEMPO mean in a TAF, and how is it different from BECMG?
TEMPO forecasts a temporary fluctuation expected to last under an hour at a time within its stated window. BECMG forecasts a gradual change that becomes established by the end of its window (remote_pilot_study_guide.pdf, pp. 18–19).
Why does high humidity increase density altitude?
Water vapor is lighter than air, so moist air is less dense than dry air at the same temperature and pressure — less-dense air means a higher density altitude and reduced performance, though humidity is a smaller factor than pressure or temperature (remote_pilot_study_guide.pdf, p. 22).
Remote ID
What are the three ways to comply with Remote ID?
Operate a standard remote identification aircraft that broadcasts its own position and the control station's (§ 89.110); equip a broadcast module and keep the aircraft within visual line of sight (§ 89.115(a)); or fly with no RID equipment at all inside an FAA-Recognized Identification Area, FRIA (§ 89.115(b)).
Can ADS-B Out satisfy the Remote ID requirement?
No. 14 CFR § 89.125 states plainly that ADS-B Out equipment cannot be used to comply with part 89's remote identification requirements.
What counts as civil twilight for part 107 night-lighting purposes?
Outside Alaska, 30 minutes before official sunrise until sunrise, and official sunset until 30 minutes after sunset (14-cfr-107.txt, § 107.29(c)). Alaska uses the Air Almanac's own definition.
Can a remote pilot turn off anti-collision lighting at night?
No — the PIC may reduce its intensity when it's in the interest of safety, but may never extinguish it entirely (14-cfr-107.txt, § 107.29(a)(2)).
What is Remote ID, and does my drone need it?
Remote ID is a drone's digital "license plate" — a broadcast of its identity and location in flight. Since September 16, 2023, almost every drone that must be registered needs it, met either by flying a standard Remote ID aircraft, adding a broadcast module, or flying only inside an FAA-Recognized Identification Area (14-cfr-89.txt, §§ 89.105, 89.110, 89.115).
Who Needs a Part 107 Certificate
Do I need a Part 107 certificate to fly a drone just for fun?
No. Flying strictly for recreational purposes falls under 49 U.S.C. § 44809 instead, which has its own conditions — a passed recreational safety test, flight within visual line of sight, staying under 400 ft. AGL in uncontrolled airspace, and following a community-based organization's safety guidelines (AC_107-2A.pdf, § 4.1, footnote 1, p. 4-1).
Is the Part 107 test the same as the TRUST test?
No — they're different tests for different purposes. The recreational safety test required under § 44809(g) (often called TRUST, though our source material cites it only by that regulatory section) is free and covers hobby flying. The Part 107 UAG knowledge test is the FAA's paid certification exam for commercial and other non-recreational small UAS operations, scored at 70% to pass (AC_107-2A.pdf, § 4.1, p. 4-1; UAG_Information_Bulletin.pdf, p. 4).
What counts as commercial drone use?
The FAA's rules don't actually define "commercial" as a formal term. Part 107 applies to any drone operation that doesn't qualify as recreational flying under 49 U.S.C. § 44809(a) — so if you're not flying strictly for your own enjoyment within that section's conditions, part 107 applies, regardless of whether money changes hands (AC_107-2A.pdf, § 4.1, p. 4-1).
Is a Part 107 certificate the same as a pilot's license?
No. It's a separate FAA airman certificate specific to small UAS, called a Remote Pilot Certificate with a small UAS rating — it doesn't require, and isn't the same as, a manned-aircraft pilot certificate issued under 14 CFR part 61, though part 61 certificate holders who stay current can qualify through an alternate path (AC_107-2A.pdf, §§ 6.3–6.4, p. 6-1).
