Overview
The Aviation Information subtest measures your knowledge of aeronautical concepts, aircraft systems, flight principles, and aviation terminology. It is one of the most domain-specific subtests on the AFOQT — unlike Math Knowledge or Word Knowledge, which test broadly applicable skills, Aviation Information tests knowledge specific to flight and aircraft.
Aviation Information feeds two composites: Pilot and ABM. For candidates pursuing these career fields, it is a direct priority. Candidates from non-aviation backgrounds often find this subtest the most foreign, but the content is finite and trainable — focused study from standard aviation references produces measurable score gains.
Format and Timing
You will have 8 minutes to answer 20 questions — 24 seconds per question. Questions are multiple choice with four or five answer options. Pacing is tight but manageable with content familiarity; candidates who know the material can usually complete the section comfortably, while candidates who are reasoning from first principles run out of time.
Content areas include:
- Flight principles: lift, drag, thrust, weight, angle of attack, stall
- Aircraft control surfaces: ailerons, elevators, rudder, flaps, trim
- Aircraft axes and motions: pitch, roll, yaw
- Aerodynamics fundamentals: Bernoulli's principle, airflow, wing design
- Aircraft components: fuselage, empennage, landing gear, engine types
- Flight instruments: altimeter, airspeed indicator, attitude indicator, heading indicator, turn coordinator, vertical speed indicator
- Navigation basics: headings, bearings, VOR, GPS fundamentals
- Aviation terminology: knots, feet AGL/MSL, standard aviation abbreviations
- Weather and atmospheric conditions: density altitude, icing, turbulence basics
- Airport operations: runway numbering, traffic pattern, common procedures
The depth is comparable to a private pilot ground school primer — you need conceptual familiarity, not FAA-certified expertise.
Composite Relevance
Aviation Information contributes to two composites:
- Pilot composite (minimum 25 required for pilot candidates)
- ABM composite (minimum 25 required for ABM candidates)
For pilot candidates, Aviation Information is one of four subtests (Math Knowledge, Table Reading, Instrument Comprehension, Aviation Information) that determine the Pilot composite. Each subtest is roughly a quarter of the score, so a weak Aviation Information performance is difficult to compensate elsewhere. Aspiring pilots should treat this as a top-tier study priority.
For ABM candidates, Aviation Information is one of six subtests feeding the ABM composite. The load is distributed across more subtests, so any individual subtest contributes proportionally less — but Aviation Information still matters and should not be neglected.
For CSO candidates, Aviation Information does not feed the CSO composite and can be deprioritized relative to Word Knowledge, Math Knowledge, Table Reading, and Block Counting.
For non-rated candidates, Aviation Information is not a study priority.
Strategy and Approach
Use the FAA Pilot's Handbook of Aeronautical Knowledge as a primary reference. The FAA publishes this handbook free online (the "PHAK"), and it covers virtually all Aviation Information content at an appropriate depth. Skim the chapters on aerodynamics, flight instruments, aircraft systems, and basic navigation. You do not need to memorize it cover to cover — familiarity with the core concepts is sufficient.
Memorize the three axes and their control surfaces. This is foundational aviation knowledge and appears in some form on nearly every Aviation Information practice set:
- Pitch — rotation around the lateral axis, controlled by the elevator
- Roll — rotation around the longitudinal axis, controlled by the ailerons
- Yaw — rotation around the vertical axis, controlled by the rudder
If you know nothing else about aircraft control, know this.
Learn the six-pack of primary flight instruments. The standard analog instrument panel in general aviation aircraft has six primary instruments, commonly called the "six-pack":
- Airspeed indicator
- Attitude indicator (artificial horizon)
- Altimeter
- Turn coordinator
- Heading indicator
- Vertical speed indicator
Knowing what each measures and how each is read is directly relevant to both Aviation Information and Instrument Comprehension.
Understand the four forces of flight. Lift, drag, thrust, and weight are the four forces acting on any aircraft. In steady level flight, lift equals weight and thrust equals drag. This relationship underlies many conceptual Aviation Information questions about climbs, descents, and turns.
Build vocabulary systematically. Aviation has a specific lexicon — empennage, aileron, flaps, slats, trim, yoke, stick, throttle, stall, buffet, ground effect, density altitude. Candidates from non-aviation backgrounds often lose points simply by not recognizing terminology. Build a vocabulary list as you study and quiz yourself on definitions.
Skip unfamiliar questions strategically. With 24 seconds per question and content that is either known or not, extended reasoning rarely converts a "don't know" into a correct answer. If a question involves terminology or a concept you don't recognize, make a disciplined guess and move on. There is no penalty for incorrect answers, so always bubble something.
Example Question
Question: Which control surface is primarily responsible for controlling the aircraft's pitch?
- (A) Ailerons
- (B) Rudder
- (C) Elevator
- (D) Flaps
- (E) Trim tab
Analysis:
- (A) Ailerons control roll, not pitch.
- (B) Rudder controls yaw.
- (C) The elevator, located on the horizontal stabilizer at the tail of the aircraft, controls pitch — the nose-up or nose-down motion.
- (D) Flaps change the shape of the wing to increase lift at lower speeds; they are not a primary pitch control.
- (E) Trim tabs adjust control surface positions to reduce pilot workload but are not the primary pitch control.
Best answer: (C) Elevator
This is foundational aviation content, and the question illustrates the test's preference for direct, concept-based questions over calculation-heavy ones. Knowing the pitch/roll/yaw correspondence with elevator/aileron/rudder answers this question in about 5 seconds.
