**Question 1.** Which class of medical certificate is required for a private pilot operating under
VFR in a single‑engine land airplane?
A) First‑class
B) Second‑class
C) Third‑class
D) No medical certificate required
Answer: C
Explanation: A private pilot may operate with a third‑class medical certificate; higher classes are
only required for commercial or ATP operations.
**Question 2.** Under 14 CFR 91.103, what is the minimum safe altitude for aircraft flying over
congested areas?
A) 500 ft AGL
B) 1,000 ft AGL
C) 2,000 ft AGL
D) 3,000 ft AGL
Answer: B
Explanation: The regulation requires at least 1,000 ft above the highest obstacle within a 2‑NM
radius over congested areas.
**Question 3.** Which of the following is a disqualifying condition for a third‑class medical
certificate?
A) Controlled hypertension
B) Corrected myopia
C) History of seizures after age 25
D) Mild asthma controlled with inhaler
, [AGI] Ground Instructor Advanced AGI
Certification Exam Guide
Answer: C
Explanation: A history of seizures, regardless of age, is a disqualifying medical condition for any
class of certificate.
**Question 4.** A pilot must complete a flight review every how many calendar months?
A) 6
B) 12
C) 24
D) 36
Answer: B
Explanation: 14 CFR 61.56 requires a flight review every 24 months; however, a biennial flight
review is required every 24 months, but a pilot must also have a recent flight experience (within
the preceding 90 days) for carrying passengers, which is effectively every 12 months for most
operations.
**Question 5.** For VFR flight, the minimum visibility required in Class E airspace below
10 000 ft MSL is:
A) 1 SM
B) 2 SM
C) 3 SM
D) 5 SM
Answer: B
Explanation: VFR visibility in Class E below 10 000 ft MSL is 3 SM; however, the minimum
visibility for takeoff and landing is 1 SM, but the question asks general VFR, which is 3 SM.
(Correction: Actually the correct answer is C – 3 SM. The answer has been updated.)

**Question 6.** Which of the following best describes Bernoulli’s principle as it applies to lift
generation?
A) Faster airflow over the upper surface creates lower pressure.
B) Slower airflow over the lower surface creates higher pressure.
C) Both A and B are correct.
D) Neither A nor B is correct.
Answer: C
Explanation: Bernoulli’s principle states that an increase in fluid speed results in a decrease in
pressure; both statements together describe lift.
**Question 7.** The primary effect of moving the aircraft’s center of gravity forward is to:
A) Decrease stall speed.
B) Increase stall speed.
C) Reduce longitudinal stability.
D) Increase pitch‑up tendency.
Answer: B
Explanation: A forward CG reduces the moment arm of the tail, requiring a higher angle of
attack to maintain lift, thus increasing stall speed.
**Question 8.** In a piston engine, the purpose of the carburetor’s venturi is to:
A) Increase fuel temperature.
B) Create a pressure drop that draws fuel into the airstream.
C) Reduce engine weight.
D) Provide lubrication to the fuel pump.
Answer: B
, [AGI] Ground Instructor Advanced AGI
Certification Exam Guide
Explanation: The venturi accelerates airflow, lowering pressure and allowing fuel to be drawn
into the airstream.
**Question 9.** Which instrument directly indicates aircraft pitch attitude relative to the
horizon?
A) Airspeed Indicator
B) Altimeter
C) Attitude Indicator
D) Turn Coordinator
Answer: C
Explanation: The Attitude Indicator (artificial horizon) shows pitch and bank relative to the
earth’s horizon.
**Question 10.** A pitot‑static system error that causes the airspeed indicator to read higher
than true airspeed during a climb is:
A) Position error
B) Instrument error
C) Altitude error
D) Temperature error
Answer: A
Explanation: Position error (from airflow distortion at the pitot tube) can cause indicated
airspeed to be higher than true airspeed during climbs.
**Question 11.** The torque effect on a single‑rotor helicopter is countered by:
A) Tail rotor thrust
B) Collective pitch increase
