Part 107 practice test questions, explained
How Part 107 test questions are built, where the trap usually hides, and three worked examples with the FAA source behind every answer.
You’ve read the rules, you know the 400-foot limit, and then a practice question comes back wrong on something you were sure about. That’s frustrating, and it’s also useful. Most missed questions aren’t about rules you’ve never seen. They come from the way the question is worded.
Here’s the math you’re working with. The Part 107 knowledge test is 60 multiple-choice questions in two hours, and you need 70% to pass, which works out to 42 correct answers. Knowing the rules gets you most of the way there. The rest comes from reading each question the way it was written.
This guide covers the question format, the habits that cost people points, and three worked examples you can check against the source yourself. If you’d rather try the format first, take the free 20-question practice test and come back.
What a test question looks like
Every question is objective multiple choice. Each has one correct response and stands on its own, so no question depends on another. All 46 questions in the FAA’s published sample set have three options, A to C.
Some questions send you to a figure in the testing supplement, FAA-CT-8080-2H, a booklet the test center hands you. The test also includes some questions with an image embedded in the question itself, and from October 26, 2026 those grow to include images taken from current sectional charts. What changes on the Part 107 test on October 26 has the details.
Here’s a figure question from the FAA sample set: “(Refer to FAA-CT-8080-2H, Figure 22, area 2.) At Coeur D’Alene which frequency should be used as a Common Traffic Advisory Frequency (CTAF) to monitor airport traffic?” The FAA’s sample PDF comes with no answer key. If a site grades the FAA samples without showing where each answer came from, check its answers against the source before you trust them.
PSI also gives you 5 unscored validation questions on top of the 60 scored ones, and the time limit already allows for them. You won’t know which ones they are, so answer every question as though it counts.
Where the questions come from
The test is built on the Remote Pilot Airman Certification Standards (ACS), FAA-S-ACS-10B, which is the FAA’s official list of what the test can ask. It divides the knowledge into five areas. The ACS gives a percentage range for each one, and PSI’s current applicant bulletin gives a single weight based on a 2025 job task analysis.
| Area | ACS range | PSI bulletin (Sept 2025) |
|---|---|---|
| I. Regulations | 15 to 25% | 48% |
| II. Airspace and requirements | 15 to 25% | 20% |
| III. Weather | 11 to 16% | 5% |
| IV. Loading and performance | 7 to 11% | 2% |
| V. Operations | 35 to 45% | 25% |
The two documents disagree. We treat the ACS as the authority on what content can appear and the PSI bulletin as a description of how the test is weighted today. In practice, that means regulations deserve your first and longest study sessions.
Every question maps to an ACS code. The FAA’s sample question about operating in Class C airspace carries UA.II.A.K1b, for example. When you finish the real test, your Airman Knowledge Test Report lists the ACS codes of the questions you missed, which tells you exactly what to review if you need a retake.
Habits that cost points
Mixing up AGL and MSL. Part 107’s altitude limit is in feet above ground level (AGL). Aeronautical charts print altitudes in feet above mean sea level (MSL) unless marked otherwise. An answer that’s right in one reference is wrong in the other.
Half-remembering the numbers. Cloud clearance is 500 feet below and 2,000 feet horizontally. Minimum visibility is 3 statute miles from the control station. An option that swaps two of those numbers looks right if you learned them loosely.
Picking the option that sounds most careful. In the FAA sample question on flying in Class C airspace, one option says to monitor the ATC frequency and another says to contact ATC after launch. Both sound responsible. The rule requires prior authorization from ATC, so neither one is correct.
Forgetting who a rule covers. The alcohol rules apply to the remote PIC (pilot in command), the person at the controls and the visual observer. Any of them breaks the rule by acting within 8 hours of a drink or with an alcohol concentration of 0.04 or more.
Worked example 1: altitude near a structure
We wrote these three questions to match the format of the test. They aren’t FAA questions.
This first one comes straight out of inspection work, like shooting a cell tower for a client.
You are inspecting a 300-foot tower and stay within 400 feet of it the whole time. Under 14 CFR part 107, what is the highest you may fly?
A. 400 feet AGL
B. 700 feet AGL
C. 400 feet above the tower, at any distance from it
Answer: B. The normal limit is 400 feet AGL. The exception in §107.51(b) applies within a 400-foot radius of a structure: you may fly up to 400 feet above the structure’s immediate uppermost limit. That’s 300 plus 400, or 700 feet AGL.
Option A ignores the exception. Option C keeps the height but drops the 400-foot radius, and the radius is what makes the higher altitude legal. When an option restates a rule with one condition missing, that’s usually the wrong one.
Worked example 2: a METAR and cloud clearance
This is the check you’d run on the morning of a real shoot, before you drive out.
The closest reporting station, and the one most representative of your site, reports:
METAR KXYZ 131755Z 27012G18KT 5SM BR OVC006 17/15 A3001What is the highest you can fly while meeting Part 107 weather minimums?A. 400 feet AGL
B. 100 feet AGL
C. You can’t fly, because visibility is below the minimum
Answer: B. Decode it group by group. 27012G18KT is wind from 270 degrees true at 12 knots, gusting 18. 5SM is 5 statute miles visibility, and BR is mist. OVC006 is an overcast layer at 600 feet AGL, since cloud heights are given in hundreds of feet above ground level.
Five statute miles beats the 3-mile minimum, so C is wrong. You must stay at least 500 feet below clouds, and 600 minus 500 leaves 100 feet AGL. Option A is the Part 107 altitude limit, but these clouds make it impossible to reach legally.
AC 107-2A points you to the closest station that best represents your terrain, which is why the question says so. For more practice, read METAR and TAF decoding for Part 107 or paste a report into the METAR decoder.
Worked example 3: load factor in a turn
A fixed-wing small unmanned aircraft holds altitude in a coordinated turn at a 60-degree bank. What load factor does its structure carry?
A. 1.5 G
B. 2 G
C. 3 G
Answer: B. The FAA Remote Pilot Study Guide states that the load factor for any aircraft in a coordinated level turn at a 60-degree bank is 2 Gs. Past about 72 degrees it reaches 3 Gs, which is where option C comes from.
The test likes a follow-up here: a higher load factor raises stall speed. Stall speed rises with the square root of the load factor, so an aircraft that stalls at 50 knots in level flight can stall at 100 knots at 4 Gs. Load factor and density altitude on the Part 107 test walks through the rest.
How to use practice questions well
A practice question teaches you the most right after you get it wrong. Every time you miss one, find the sentence in the regulation or handbook that settles it and read the paragraphs around it. That’s why every answer in Liftoff cites its FAA or eCFR source.
Once you’ve covered all five areas, move on to full-length timed sets. Sixty questions in two hours feels different from ten over a coffee break, and knowing your pace ahead of time means test day holds fewer surprises.
Group your misses by area and compare them with the weights above. Under PSI’s weighting, a weak spot in regulations costs far more than one in loading and performance. Two references help most: the Part 107 rules cheat sheet for the numbers, and how to read a sectional chart for figure questions.
