1What is the minimum age to be eligible for a private pilot certificate with a glider category rating?
A.16 years
B.14 years
C.17 years
D.18 years
Explanation: Under 14 CFR 61.103, an applicant for a private pilot certificate with a glider rating must be at least 16 years old. This differs from the 17-year minimum required for airplane and other powered categories.
2A glider's best glide speed corresponds to which point on the glide polar?
A.The lowest point on the curve
B.The point of tangency from a line drawn from the origin
C.The right-most point on the curve
D.The speed where sink rate equals zero
Explanation: Best glide (best L/D) is found where a straight line drawn from the origin is tangent to the glide polar; this point yields the flattest possible glide angle and maximum distance per altitude lost in still air.
3Which speed allows a glider to remain airborne the longest when descending through still air?
A.Maneuvering speed
B.Best L/D speed
C.Minimum sink speed
D.Maximum rough-air speed
Explanation: Minimum sink speed is the lowest point on the glide polar, producing the smallest rate of descent. Because the glider loses altitude most slowly there, it stays aloft longest in still air and is the speed used when thermalling.
4During an aerotow, the towplane pilot rocks the wings (rudder waggle/wing rock). What does this signal mean to the glider pilot?
A.You are too high; lower the glider
B.Increase speed
C.Something is wrong; check your glider
D.Release immediately
Explanation: A wing rock signal from the towplane is the visual command for the glider to release immediately. The glider pilot should release at once and maneuver clear of the towplane.
5The glider pilot rocks the wings during an aerotow while the tow continues. What is this signal telling the towplane pilot?
A.Something is wrong with the towplane
B.I cannot release; open your spoilers
C.I am about to release
D.Increase tow speed
Explanation: When the glider rocks its wings during tow, it signals the towplane that something is wrong with the towplane (for example, spoilers appear open or smoke is visible). The towplane pilot should check the aircraft and prepare to land.
6A thermal is best described as a source of lift produced by which mechanism?
A.Wind deflected upward by terrain
B.Rising columns or bubbles of air warmed by uneven surface heating
C.A standing wave downwind of a mountain ridge
D.Two air masses converging at a boundary
Explanation: Thermals form when the sun heats the surface unevenly, causing warmer, less dense air to rise as bubbles or columns. Glider pilots circle within thermals to gain altitude.
7Ridge (slope) lift is produced when wind:
A.Is heated by the sun and rises in columns
B.Forms a stationary wave many miles downwind of mountains
C.Strikes a ridge or hill and is forced upward along the slope
D.Sinks rapidly on the lee side of terrain
Explanation: Ridge lift occurs when wind blowing toward a ridge or hill is deflected upward along the windward slope. A glider can soar along the ridge in the band of rising air as long as the wind has a component perpendicular to the ridge.
8What is the primary purpose of water ballast carried in a high-performance glider?
A.To lower the stall speed
B.To reduce wing loading for thermalling
C.To move the center of gravity aft
D.To improve the glide ratio at high speeds and increase cross-country average speed
Explanation: Water ballast increases wing loading, which raises the optimum cruising speeds and improves the glide performance at higher speeds. On strong soaring days this lets the glider fly faster between thermals, increasing average cross-country speed.
9Adverse yaw in a glider causes the nose to initially move:
A.Opposite to the direction of the intended turn
B.In the same direction as the intended turn
C.Straight down
D.Toward the high wing only in a steep turn
Explanation: When ailerons are deflected to roll into a turn, the down-going aileron on the rising wing creates more induced drag, yawing the nose opposite to the intended turn. Gliders, with their long wings, exhibit pronounced adverse yaw, so coordinated rudder is essential.
10Spoilers or dive brakes on a glider are used primarily to:
A.Increase lift during the landing flare
B.Control the glide path and rate of descent on approach
C.Reduce adverse yaw in turns
D.Increase the best glide ratio
Explanation: Spoilers/dive brakes spoil lift and add drag, steepening the descent without increasing airspeed excessively. This lets the pilot control the approach angle and aim point precisely during landing.

About the FAA Private Pilot — Glider (PGL) Exam

The FAA Private Pilot — Glider Knowledge Test (code PGL) is the airman knowledge test for the private pilot certificate with a glider category rating. It is a 60-question, computer-delivered multiple-choice exam administered through PSI, with a 2.5-hour time limit and a 70% passing score. The test covers federal aviation regulations and airspace, glider aerodynamics and soaring performance, aviation weather and lift sources, launch methods and operations, weight and balance, cross-country soaring, and aeromedical/human-factors and aeronautical decision-making.

FAA Private Pilot — Glider (PGL) Study Tips from Top Performers

1Weight your study toward the largest areas: glider aerodynamics/soaring performance and soaring weather together make up roughly 40% of the content.
2Learn the glide polar cold — be able to point to minimum sink, best L/D, and how wing loading and ballast shift the curve.
3Memorize the aerotow signals (towplane wing rock = release; rudder waggle = check your glider/spoilers; glider wing rock = something wrong with the towplane) and the dangerous kiting upset.
4Drill the FARs that show up most: VFR minimums (91.155), right-of-way (91.113), towing/safety links (91.309), oxygen (91.211), and preflight action (91.103).
5When you miss a question, sort it by knowledge area and error type (regulation recall, aerodynamic reasoning, weather interpretation, or procedure) so you can target weak spots.

Frequently Asked Questions

What is the FAA PGL test and what is on it?

PGL is the FAA Airman Knowledge Test code for the Private Pilot — Glider certificate. It is a 60-question multiple-choice exam covering federal aviation regulations and airspace, glider aerodynamics and soaring performance, aviation weather and lift sources, launch and operating procedures, weight and balance, cross-country soaring, and aeromedical and decision-making topics.

How many questions and how much time does the PGL test allow?

The official FAA PGL knowledge test has 60 multiple-choice questions with a 2.5-hour time limit. This free practice bank provides 100 selected-response questions so you can drill every knowledge area with more repetition than the official test contains.

What score do I need to pass the PGL knowledge test?

You must score at least 70% to pass the FAA Private Pilot — Glider knowledge test. The test is delivered by computer at PSI testing centers, and you receive an Airman Knowledge Test Report showing your result and any subject codes for missed areas.

How much does the PGL test cost and who administers it?

The FAA airman knowledge test for gliders is administered by PSI at authorized testing centers, with a testing fee of about $175. Confirm the current fee directly with PSI when you schedule, because fees can change.

Do I need a medical certificate or an endorsement to take the PGL test?

No FAA medical certificate is required to exercise glider pilot privileges. Under 14 CFR Part 61 you generally need an instructor endorsement certifying you are prepared before you take the knowledge test, and you must meet the aeronautical experience and training requirements for the glider rating.

Are there any 2026 changes to the FAA PGL test?

As of 2026 the FAA continues to administer the Private Pilot — Glider knowledge test under the code PGL as a 60-question, 2.5-hour, computer-delivered test through PSI with a 70% passing standard. Always verify the current Airman Certification Standards and test details on the FAA website before testing.
