FAA Ground Instructor Written Exam (FOI, FIA, AGI, IGI) — Questions and Answers
Question 1: What is drag in aviation?
- Landing force
- A lifting force
- Engine thrust
- Air resistance opposing motion (Correct answer)
Correct answer: Air resistance opposing motion
Drag is the aerodynamic force that opposes an aircraft's motion through the air. It is primarily caused by the friction between the aircraft's surface and the air, as well as pressure differences created by the aircraft's shape. This resistance must be overcome by thrust for the aircraft to maintain or increase speed.
Question 2: What is 'plan continuation bias' (press-on-itis) in the context of flight safety?
- The inclination to follow ATC vectors rather than direct routing
- Overconfidence in the original weather forecast
- The cognitive bias to continue a planned course of action despite new information that warrants a change (Correct answer)
- The tendency to file updated flight plans when conditions change
Correct answer: The cognitive bias to continue a planned course of action despite new information that warrants a change
Plan continuation bias causes pilots to press on with the original plan even when changing conditions should trigger a diversion or return to departure.
Question 3: What is an effective way to provide feedback to students?
- Provide specific and constructive feedback (Correct answer)
- Ignore errors
- Give general praise
- Criticize harshly in public
Correct answer: Provide specific and constructive feedback
Providing specific and constructive feedback is the most effective way to help students learn and improve. This type of feedback clearly identifies areas for improvement and offers actionable suggestions, rather than just general praise or criticism. It allows students to understand exactly what they did well and what needs adjustment, fostering growth and skill development.

- Stall speed increases proportionally to flap angle
- Stall speed increases because of added drag
- Stall speed decreases because of increased lift at a given airspeed (Correct answer)
Correct answer: Stall speed decreases because of increased lift at a given airspeed
Lowering flaps increases the wing's camber and lift coefficient, allowing the wing to stall at a lower airspeed.
Question 34: Where is wind shear most likely to be encountered near a thunderstorm?
- Only in the stratiform rain region behind the storm
- Only at high altitudes above the anvil
- Near the surface directly below the storm and at all altitudes within 20 NM (Correct answer)
- Exclusively in the anvil cloud outflow
Correct answer: Near the surface directly below the storm and at all altitudes within 20 NM
Wind shear associated with thunderstorms can occur near the surface under the storm and within approximately 20 NM of the cell at any altitude.
Question 35: What is the purpose of filing a VFR flight plan?
- It provides ATC with authorization to vector the pilot around weather
- It activates ATC radar flight following automatically
- It ensures search and rescue will be initiated if the flight is overdue and the plan is not closed (Correct answer)
- It is required for all cross-country flights over 25 nautical miles

- Ensure regulatory compliance only
- Manage safety proactively (Correct answer)
- Track passenger numbers
Correct answer: Manage safety proactively
Safety Management Systems (SMS) in aviation are designed to systematically identify hazards, assess risks, and implement mitigation strategies before incidents occur. Unlike simply ensuring compliance, SMS fosters a proactive safety culture that continuously improves safety performance through data analysis and continuous monitoring.
Question 43: What principle explains how lift is generated on a wing?
- Archimedes’ Principle
- Pythagorean Theorem
- Newton’s First Law
- Bernoulli’s Principle (Correct answer)
Correct answer: Bernoulli’s Principle
Bernoulli's Principle explains that as the speed of a fluid increases, its pressure decreases. An aircraft wing is shaped as an airfoil, causing air to flow faster over its curved upper surface than its flatter lower surface. This speed difference creates a pressure differential, with lower pressure above the wing and higher pressure below, generating the upward force of lift.
Question 44: When planning a cross-country flight, what is a 'checkpoint'?
- A fuel stop required by regulation every 150 NM
- An airspace boundary requiring a radio call
- A mandatory position report required by ATC
- A prominent visual landmark along the route used to verify navigation accuracy (Correct answer)

Question 47: What is yaw in aircraft movement?
- Vertical movement
- Rotation along vertical axis (Correct answer)
- Up and down motion
- Spinning motion
Correct answer: Rotation along vertical axis
Yaw refers to the rotation of an aircraft around its vertical axis, causing the nose to move left or right. This movement is primarily controlled by the rudder, located on the vertical stabilizer. Yaw is essential for coordinated turns and maintaining directional control during flight.
Question 48: What is 'best glide speed' (Vbg)?
- Speed that produces maximum climb rate with engine at idle
- Speed that minimizes fuel consumption in cruise
- Minimum speed for controlled flight
- Airspeed that provides maximum glide distance over the ground in an engine-out situation (Correct answer)
Correct answer: Airspeed that provides maximum glide distance over the ground in an engine-out situation
Best glide speed maximizes the lift-to-drag ratio, giving the greatest horizontal distance for a given altitude loss during an engine-out glide.
Question 49: What is the purpose of a fuel endurance calculation in cross-country flight planning?
- Determines minimum altitude for VFR flight
- Calculates the most fuel-efficient altitude for cruise
- Estimates turbulence severity along the route
- Determines how long the aircraft can fly on available fuel, factoring in required reserves (Correct answer)
Correct answer: Determines how long the aircraft can fly on available fuel, factoring in required reserves
Fuel endurance calculations determine total usable flight time based on fuel quantity, consumption rate, and required reserves to ensure the flight can be completed safely.
Question 50: What causes a stall in flight?
- Insufficient fuel
- Exceeding critical angle of attack (Correct answer)
- Lack of navigation
- Engine overheating
Correct answer: Exceeding critical angle of attack
A stall occurs when an aircraft's wing exceeds its critical angle of attack, regardless of airspeed. At this point, the smooth airflow over the upper surface of the wing separates, becoming turbulent and unable to generate sufficient lift. This sudden loss of lift causes the aircraft to lose altitude or descend rapidly.
Question 51: Which front typically produces the most extensive area of clouds and precipitation?
- Warm front (Correct answer)
- Stationary front
- Cold front
- Occluded front
Correct answer: Warm front
Warm fronts produce extensive areas of stratiform clouds and precipitation that can extend hundreds of miles ahead of the surface front.
