FAA Ground Instructor (Advanced) Knowledge Test Practice Test

The FAA Ground Instructor (Advanced) Knowledge Test covers aviation knowledge a ground instructor uses to explain aircraft operation, flight planning, regulations, and instructional material. The practice bank includes questions on flight instruments, atmospheric effects on engines, weight-and-balance implications, altimeter settings, airworthiness directives, VFR charts, and flight-plan requirements.

About the FAA Ground Instructor (Advanced) Knowledge Test Exam

Advanced ground instruction calls for more than recalling definitions: instructors must connect operating rules and aircraft information to clear explanations and sound decisions. Relevant skills include interpreting instrument indications, explaining how atmospheric conditions affect engine performance, and describing how center-of-gravity position can influence aircraft handling. Candidates also need to reason through practical planning and compliance questions, such as selecting an altimeter setting for pressure-altitude calculations, identifying the purpose of an airworthiness directive, and recognizing when a flight plan must be filed. Ground instructors translate these concepts into teachable steps, helping students understand how checklists, charts, regulations, and aircraft records support safe operations. Practice with scenario-style questions can sharpen the ability to distinguish related terms and explain why a particular procedure or operating consideration matters.

Sample Practice Questions

Review a selection from this exam's published US Practice Tests practice bank.

Question 1

A pilot is explaining how a turn coordinator responds to aircraft motion. Which movement does its miniature airplane primarily indicate?

  1. AYaw and roll rate
  2. BPitch attitude and vertical speed
  3. CHeading and magnetic variation
  4. DIndicated airspeed and angle of attack
Show answerCorrect answer: A

A turn coordinator senses roll and yaw motions and indicates the rate and direction of a turn. Its inclinometer ball separately helps show whether the turn is coordinated.

Question 2

A ground instructor is teaching how a carburetor can form ice. Which condition can promote carburetor icing even when the outside air temperature is above freezing?

  1. AA drop in pressure and fuel vaporization that cool the carburetor throat
  2. BAn increase in engine oil temperature during cruise
  3. CA high battery charge during engine start
  4. DA reduction in propeller blade angle during descent
Show answerCorrect answer: A

Pressure reduction in the carburetor venturi and fuel vaporization can substantially lower local temperature, allowing ice to form under conditions where the outside air temperature is above freezing. Carburetor icing is possible across a broad range of temperatures and humidity.

Question 3

A pilot is explaining the effect of a forward center of gravity within approved limits. Compared with an aft center of gravity, what characteristic is generally more likely?

  1. AGreater longitudinal stability and a higher control force requirement
  2. BLess longitudinal stability and a lower stall speed in all conditions
  3. CNo change in stability, control forces, or stall behavior
  4. DA guaranteed increase in maximum cruise speed
Show answerCorrect answer: A

Within approved limits, a forward center of gravity generally increases longitudinal stability and can require greater control force, including during rotation and flare. The exact performance effects depend on the aircraft and loading.

Question 4

A pilot is calculating pressure altitude. Which altimeter setting should be used for this calculation?

  1. AThe current local altimeter setting
  2. B29.92 inches of mercury
  3. CThe aircraft's field elevation in feet
  4. DThe forecast temperature at cruising altitude
Show answerCorrect answer: B

Pressure altitude is the altitude indicated when the altimeter is set to 29.92 inches of mercury. It is used in performance calculations and in determining flight levels at higher altitudes.

Question 5

A ground instructor is explaining the privileges of a Ground Instructor certificate. Which statement about a Basic Ground Instructor certificate is generally correct?

  1. AIt permits the holder to provide ground training and endorsements only within the certificate's applicable privileges and limitations.
  2. BIt permits the holder to give flight training in any aircraft category.
  3. CIt automatically authorizes the holder to conduct practical tests for pilot certificates.
  4. DIt permits the holder to endorse a student for solo flight without any required flight instructor involvement.
Show answerCorrect answer: A

Ground Instructor certificate privileges are limited to ground instruction and associated endorsements authorized by regulation. They do not include flight instruction or practical-test examiner authority. Specific endorsement privileges depend on the certificate level and applicable requirements.

Question 6

A student asks why pilots use a checklist during normal aircraft operations. Which explanation is most accurate?

  1. AA checklist helps ensure required actions are completed in a consistent sequence and reduces reliance on memory.
  2. BA checklist transfers responsibility for aircraft operation from the pilot to the aircraft manufacturer.
  3. CA checklist guarantees that mechanical failures will not occur.
  4. DA checklist is intended only for pilots who have not memorized the aircraft systems.
Show answerCorrect answer: A

Checklists support consistent completion of important tasks and help guard against omissions, especially when workload is high. They do not replace pilot judgment, required training, or maintenance, and they cannot prevent every failure.

Question 7

A ground instructor is teaching a student how to determine whether a particular aircraft may be operated under an Airworthiness Directive. Which statement best describes an AD?

  1. AIt is an optional manufacturer recommendation that becomes mandatory only if adopted by the owner.
  2. BIt is a legally enforceable rule issued to correct an unsafe condition in a product.
  3. CIt is a maintenance record used instead of an annual inspection.
  4. DIt applies only to aircraft operated by commercial air carriers.
Show answerCorrect answer: B

An Airworthiness Directive is a legally enforceable regulation issued when an unsafe condition exists and is likely to exist or develop in other products of the same type design. Applicable ADs must be complied with unless an approved alternative method is authorized.

How to use this practice test

The free US Practice Tests bank contains 50 published practice questions. Each session presents up to 20 questions selected at random, with results shown after completion. Use missed or uncertain items to identify concepts that need clarification, such as instrument interpretation, aircraft airworthiness, or flight-planning decisions.

Preparation tips

  • Practice explaining how a turn coordinator’s miniature airplane responds to aircraft motion, and distinguish its indication from other attitude instruments.
  • Work through carburetor-icing scenarios that account for temperature and moisture conditions rather than relying on outside air temperature alone.
  • Compare forward and aft center-of-gravity positions within approved limits, focusing on stability and control characteristics.
  • Rehearse pressure-altitude calculations and the use of local altimeter settings, including what an altimeter indicates at airport elevation.
  • Review how airworthiness directives, current aeronautical charts, VFR operations, and flight-plan filing relate to practical operating decisions.
