Prepare for the initial UAG knowledge test

Unofficial FAA Part 107 practice · Unmanned Aircraft General – Small (UAG) · UAG Applicant Information Bulletin blueprint, effective September 29, 2025 · verified October 16, 2026. FAA-S-ACS-10B is the topic and knowledge-code reference. Independently authored; no FAA affiliation or endorsement.

40 curated English questions cover selected topics across all five ACS areas. Rounds sample uniformly without replacement; domain weights are not enforced. This is untimed practice with three choices per question, not a full 60-question, two-hour exam. Concept and scenario levels are author-assigned, not calibrated difficulty.

Official UAG blueprint weights: regulations 48%; airspace 20%; weather 5%; loading/performance 2%; operations 25%. These exam weights do not control this bank’s uniform sampling; a short round can omit an area. The two original chart schematics have equivalent text; practise with full current FAA charts as well.

For the certificate: normally age 16+, English proficiency and safe physical/mental condition; the knowledge test may be taken from age 14. This targets first-time applicants, not the eligible Part 61 training pathway or recurrent training. Maintain knowledge recency every 24 calendar months; this tool grants no training credit.

FAA Recreational Drone TRUST Exam Prep Review U.S. recreational drone safety with original TRUST practice questions and FAA-linked corrections, separate from official completion.
Aircraft Weight Balance Calculator Build an aircraft weight-and-balance worksheet, track fuel burn through each phase, and check entered weight limits and the CG envelope.
Runway Crosswind Component Calculator Calculate runway wind components and gust margins with true-to-magnetic conversion, runway comparisons, and profile-adjusted thresholds.
G-Force Calculator Calculate acceleration and g ratios for speed changes, braking distance, cornering or rotation with unit conversion and clear safety limits.

A drone inspection flown at 120 feet above the ground can still require airspace approval. Inside an airport’s active Class D surface airspace, staying below 400 feet does not remove the need for prior air traffic control (ATC) authorization. Remote-pilot knowledge involves recognizing which requirements apply together, rather than treating one familiar limit as permission to fly.

In the United States, Part 107 governs many civil operations with small unmanned aircraft. The aircraft must weigh less than 55 pounds at takeoff, including everything attached or carried. The remote pilot in command has final authority and responsibility for the operation. A client’s deadline, an automatic flight route, or a functioning camera does not establish that the proposed flight is safe or permitted.

The initial Unmanned Aircraft General – Small (UAG) knowledge test is part of the first-time pathway to a Remote Pilot Certificate with a small unmanned aircraft system rating. Its subject matter connects regulations, airspace, weather, loading and performance, and operations. The Airman Certification Standards (ACS) organize those subjects into areas and tasks that help identify what needs further study.

Altitude questions often turn on the reference surface, not difficult arithmetic. Two terms must remain distinct when reading charts and applying operating limits.

Above ground level (AGL)
Height above the ground beneath the aircraft or object. A 400-foot AGL limit follows the terrain rather than a fixed sea-level elevation.
Mean sea level (MSL)
Elevation relative to the sea-level reference used for many charted airspace and obstacle values. An airspace floor of 1,800 feet MSL is not necessarily 1,800 feet above the local ground.

Weather information also needs interpretation before it becomes a flight decision. An aviation routine weather report (METAR) describes observed conditions, while a terminal aerodrome forecast (TAF) describes expected conditions during a stated period. Wind gusts, visibility and cloud conditions matter alongside aircraft-specific limits. Hotter, less-dense air can reduce aerodynamic performance even when a drone uses electric motors, and an unsecured payload can affect control despite being within its weight limit.

The official UAG bulletin specifies 60 scored questions plus five unscored validation questions, with 120 minutes allowed and a passing requirement of 70% of the scored questions correct. That knowledge-test result is only one part of certification. The first-time applicant must also complete the FAA application process and required security vetting; answering practice questions does not confer a qualification.

The minimum age to take the knowledge test is 14, but certificate eligibility begins at 16. Applicants must meet the applicable English-language and safe physical and mental condition requirements. Eligible holders of a Part 61 pilot certificate other than a student certificate, with a current flight review, have a separate training pathway. To continue operating under Part 107, pilots must meet the requirement for an applicable knowledge test or training completed within the previous 24 calendar months. This is a knowledge-recency requirement, not an automatic two-year certificate expiration.

How to Use This Tool:

Use this independent, English-language practice to work through selected UAG concepts and review the reasons behind an answer. The starting setup is five questions from All five ACS areas, with feedback after each answer.

  1. Choose a Domain / practice focus and a Question count. The all-area pool contains 40 questions and offers rounds of 3, 5, 10, 20 or 40. Individual domains have smaller menus, and the loading and performance focus offers three or four questions. Concept checks, applied scenarios, and chart notation with weather reports provide additional ways to select from the same bank.
  2. Select Learn — feedback after each answer to see the correction and explanation immediately, or Review — feedback at completion to withhold them until the completed result. Both modes are untimed and use the same scoring rules.
  3. Leave Replay seed blank for a repeatable default round, or enter a short label under Advanced to change the selection and option order. Then select Start exam practice. Long seed entries are shortened; the results show the Active seed actually used for the round.
  4. Select one of the three answer choices, then use Next unanswered question. Selecting a choice records and locks it immediately in either feedback mode. There is no separate submission step that lets you reconsider the selection, and questions cannot be skipped. After the final answer, select View results.
    End round clears the active attempt and returns to setup. It does not produce a graded result for an unfinished round.
  5. Read Missed answer review and the associated explanations before selecting Retry missed. Use Replay same seed to repeat the exact round or Try a new seed to resample or reorder the active question pool. A new seed does not guarantee previously unseen questions.

Interpreting Results:

The final fraction reports correct answers out of all questions in that round. During the round, the summary instead reports how many questions have been answered. Completion and correctness are different measures, so a full progress bar does not mean that every answer was correct.

Perfect round means there were no misses among the selected questions. It is not a readiness band or a prediction of an official pass. Review guessed answers in the Answer ledger as well as mistakes, and use the explanations and source references to check the rule or interpretation that produced the answer.

Domain performance shows counts of correct and missed answers, not calibrated proficiency scores. An area marked Not sampled in this round, or absent from the chart, was not assessed. Comparing rounds with different topics or lengths can therefore be misleading. If the chart is unavailable, the text summaries and answer ledger remain useful while you try Retry chart.

The percentages labeled official weight in the results follow the UAG blueprint effective September 29, 2025. This curated bank samples uniformly without enforcing those weights, so a practice round’s domain mix does not reproduce the official examination allocation.

Technical Details:

UAG preparation combines interpreting aeronautical information with applying the conditions in Part 107. A practice score counts correct choices on the selected questions. The sampling rules determine which subjects contribute to that score, while the underlying aviation rules determine why an answer is correct.

How points and completion are counted

Let N be the number of questions in the active round, A the number answered, and C the number answered correctly. Each correct answer earns one point. An incorrect answer earns zero, with no negative marks, partial credit, difficulty adjustment or domain weighting.

Points = C Accuracy (%) = 100×CN Progress (%) = 100×AN

N is positive, and the available score ranges from zero to N points. Unanswered questions remain in the denominator but are not counted as incorrect answers. Accuracy retains the unrounded value of 100 × C/N, while the final summary shows the exact fraction C/N. The displayed progress percentage rounds to the nearest whole percent, with a half percent rounded up. Completion requires A = N; a perfect round requires C = N.

There is no practice pass/fail cutoff. In particular, the official examination’s 70% requirement is not used to award a pass, readiness status or qualification here.

Topic coverage and the revised UAG blueprint

The question bank identifies FAA-S-ACS-10B, published in April 2021 and effective April 6, 2021, as its topic framework. Its five areas remain useful study headings. However, the FAA’s August 2025 testing advisory declared the testing blueprint in that document obsolete and directed applicants to the revised PSI bulletin effective September 29, 2025.

The practice interface displays the revised examination weights. The table compares the question inventory with those weights and the superseded ACS-10B ranges.

ACS area Bank questions Superseded ACS-10B range UAG weight from September 29, 2025
I · Regulations 14 15 to 25% 48%
II · Airspace and requirements 8 15 to 25% 20%
III · Weather 6 11 to 16% 5%
IV · Loading and performance 4 7 to 11% 2%
V · Operations 8 35 to 45% 25%

Questions are sampled uniformly without replacement from the selected focus. A question cannot repeat within one round, but short rounds can omit entire areas. Even the full 40-question round follows the bank’s composition rather than the revised exam percentages. Concept checks contain 15 items and applied scenarios contain 25. The six-item chart-and-weather focus reuses questions from those groups rather than adding new ones. Concept and scenario labels are author-assigned rather than calibrated difficulty levels.

A replay is reproducible when the bank, focus, count, feedback mode and seed remain the same. A different seed changes sampling or order, not the answer rules. Selecting all questions in a focus leaves no additional unseen items for another seed to introduce. Retrying misses creates a fresh, separately scored round containing only those missed questions.

Selected Part 107 conditions

Numeric limits depend on their comparison words and operating conditions. These examples explain recurring distinctions in the practice questions; they are not a complete flight-approval checklist. Applicable authorization conditions, waivers and other restrictions must be considered separately.

Subject Rule or boundary Consequence
Small-aircraft definition Less than 55 lb at takeoff, including everything attached or on board. Exactly 55 lb is outside the definition. Empty weight alone is insufficient.
Groundspeed No greater than 87 knots (100 mph), without a waiver. The limit concerns speed over the ground, not airspeed.
Altitude No more than 400 ft AGL unless within a 400-foot radius of a structure and no more than 400 ft above its immediate uppermost limit. Both structure conditions must hold. The exception does not override another operating restriction.
Visibility and clouds At least 3 statute miles of flight visibility from the control station, with at least 500 ft below clouds and 2,000 ft horizontal cloud separation. Staying within an altitude allowance does not remove these ordinary weather limits.
Category 1 operations over people No more than 0.55 lb throughout the operation, including attachments, and no exposed rotating parts that would lacerate human skin on impact. Low weight alone does not qualify the aircraft. Additional operating conditions still apply.

For ordinary night operations, the required initial knowledge test or training must have been completed after April 6, 2021 and include the updated night content. Anti-collision lighting must be visible for at least three statute miles and flash sufficiently to avoid collision. The remote pilot may reduce its intensity when necessary for safety, but that is not permission to extinguish it.

Airspace authorization is a separate requirement in Class B, C or D airspace and within an airport-designated Class E surface area. Class E beginning above the planned flight altitude is not the same as Class E extending to the surface. Likewise, an existing airspace authorization does not override an applicable temporary flight restriction (TFR).

Reading chart notation and weather groups

The two original chart schematics illustrate notation, with the same information also written in their questions. Their numbers are exercises rather than navigation data. Chart elevations and weather-report heights use different references, so identifying the unit and reference comes before calculation.

Notation Interpretation Common mistake
Class C shelf with 42 above 18 The ceiling is 4,200 ft MSL and the floor is 1,800 ft MSL. Both figures represent hundreds of feet. Treating the numbers as heights above local ground.
Obstacle labeled 1260 with (340) The top is 1,260 ft MSL and its height is 340 ft AGL, implying approximate ground elevation of 920 ft MSL. Adding the two numbers or treating the parenthetical height as MSL elevation.
24012G20KT Wind from 240° true at 12 knots, gusting to 20 knots. Reading a direction toward which the wind blows, a magnetic direction, or miles per hour.
SCT012 BKN025 OVC050 The ceiling is 2,500 ft AGL, set by the lowest broken layer. Scattered cloud at 1,200 ft does not establish a ceiling. Choosing the lowest cloud group without checking its coverage designation.

A reported ceiling is the lowest broken or overcast layer, or vertical visibility into an obscuration. It is not a substitute for checking visibility and actual cloud separation throughout the intended flight area.

Loading relationships

The center of gravity (CG) is found from weight and moment, not by averaging two positions without regard to weight. An arm is the distance from a chosen reference plane, called the datum. Each moment is a weight multiplied by its arm; total moment divided by total weight gives the combined CG.

xCG = ∑iWi×xi ∑iWi

Here, W is each component’s weight and x its arm measured from the same datum. With weight in pounds and arms in inches, moments are pound-inches and the resulting CG is in inches. The total weight and calculated CG still need comparison with the manufacturer’s limits, and the payload must remain secure.

For a fixed-wing aircraft in a coordinated, level turn, banking tilts the lift force. More total lift is needed to keep its vertical component equal to the aircraft’s weight. The load factor n is the lift-to-weight ratio, and φ is the bank angle.

n = 1cos⁡(φ)

At a 60° bank angle, the cosine is 0.5, so lift must support twice the weight, described as 2 G in the exercise. This relationship assumes a coordinated, level fixed-wing turn. It should not be applied unchanged to a descending turn or a hovering multirotor.

Limitations and Privacy:

The questions are independently authored, with no FAA affiliation or endorsement. The 40-item bank, identified as version 2026.09.11.1, covers selected topics rather than every ACS objective. It does not reproduce confidential examination questions, simulate the complete official test, award a certificate, or provide credit for initial or recurrent FAA training.

UAG already includes embedded images. The announced format change takes effect on October 26, 2026 and adds image-based questions that are not in the test supplement. The confirmed date appears in the FAA’s September 2026 special advisory. The two original notation schematics here do not reproduce those questions or replace practice with full current FAA charts and test-reference material.

Question explanations and dated references are study aids, not live checks of regulations, airspace or weather. No current flight conditions are retrieved. A practice result cannot establish legal authority, aircraft suitability or safe-flight competence. Actual planning requires current applicable rules, aviation information, aircraft limits and practical preparation.

Question selection and scoring run in the browser, but an attempt is not confined to private browser memory. The page address encodes the round, seed, recorded answers and current position without encryption. Anyone receiving that address may restore the attempt and see its responses. The address can remain in browser history and reach the website when opened or reloaded; exported answer ledgers also contain your responses.

Page resources, chart and document features, and opened references can require network access. Do not treat this as a fully offline service or put personal information into a replay seed.

If Saved attempt unavailable appears, start a new round to replace the invalid or incompatible saved attempt. If a warning says the attempt was not saved in the URL, keep the page open and use Retry saving before relying on that address to resume later. Changes to the question bank can make older saved attempts incompatible.

Worked Examples:

Four loading questions with one missed answer

Select IV · Loading and performance, four questions, and Review — feedback at completion. Suppose the CG question is answered with 15 inches and the other three answers are correct. The completed summary shows 3/4, equivalent to 75%. The 4 lb aircraft at a 10-inch arm contributes 40 pound-inches of moment, and the 1 lb payload at a 20-inch arm contributes 20. Dividing the total 60 pound-inches by 5 lb gives 12 inches aft of the datum. Retry missed then contains just this one question, even though the normal setup menu starts at three. A later 1/1 describes that retry, not a replacement score for the original four-question round.

A structure changes one altitude allowance

An Applied scenarios round using Learn may include a question about a structure whose top is 180 ft AGL on level terrain, with the drone 150 ft horizontally away. Selecting 580 ft AGL produces correct feedback because the drone is within the specified 400-foot radius and the altitude allowance extends 400 feet above the structure’s top. The question expressly considers only the unwaived altitude rule. Its answer does not grant permission to reach that height where an airspace authorization, cloud separation or another restriction imposes a lower limit.
