Gleim Private Pilot FAA
Knowledge Test Guide
Course
FAA Knowledge
1. Which document must be in the pilot's possession or readily accessible while acting as pilot
in command of an aircraft?
A. Passport
B. Driver's license only
C. Pilot certificate and photo identification
D. Aircraft maintenance logbook
✅ Correct Answer: C. Pilot certificate and photo identification
Rationale
A pilot acting as PIC must carry a valid pilot certificate and government-issued photo
identification.
2. The minimum age to obtain a Private Pilot Certificate (Airplane Single-Engine Land) is:
A. 16 years
B. 17 years
C. 18 years
D. 21 years
✅ Correct Answer: B. 17 years
Rationale
Applicants must be at least 17 years old to receive a Private Pilot Certificate.
3. What is the primary purpose of an altimeter?
A. Measures airspeed
B. Measures engine RPM
,C. Indicates altitude above mean sea level
D. Indicates groundspeed
✅ Correct Answer: C. Indicates altitude above mean sea level
Rationale
The altimeter measures atmospheric pressure and displays altitude relative to mean sea level
(MSL).
4. Which flight control primarily controls roll?
A. Rudder
B. Elevator
C. Ailerons
D. Trim tab
✅ Correct Answer: C. Ailerons
Rationale
Ailerons move opposite each other to create differential lift, causing the aircraft to roll.
5. The rudder primarily controls:
A. Pitch
B. Roll
C. Yaw
D. Lift
✅ Correct Answer: C. Yaw
Rationale
The rudder controls movement around the vertical axis (yaw).
6. Which aircraft instrument uses the pitot system exclusively?
,A. Airspeed indicator
B. Altimeter
C. Vertical speed indicator
D. Magnetic compass
✅ Correct Answer: A. Airspeed indicator
Rationale
Only the airspeed indicator relies on both pitot and static pressure.
7. Which instrument is powered only by the static system?
A. Altimeter
B. Heading indicator
C. Turn coordinator
D. Tachometer
✅ Correct Answer: A. Altimeter
Rationale
The altimeter uses static pressure only.
8. What is the purpose of the mixture control?
A. Adjust propeller pitch
B. Regulate fuel-air mixture
C. Control oil pressure
D. Increase flap effectiveness
✅ Correct Answer: B. Regulate fuel-air mixture
Rationale
The mixture control adjusts the fuel-to-air ratio for efficient engine operation.
, 9. What happens if carburetor ice forms?
A. Engine power decreases
B. Oil pressure increases
C. Airspeed increases
D. Fuel consumption decreases
✅ Correct Answer: A. Engine power decreases
Rationale
Ice restricts airflow into the engine, reducing power.
10. Carburetor heat should be applied when:
A. Carburetor icing is suspected
B. Fuel is low
C. During taxi only
D. Oil temperature rises
✅ Correct Answer: A. Carburetor icing is suspected
Rationale
Applying carburetor heat melts accumulated ice and restores engine performance.
11. Density altitude increases when:
A. Temperature increases
B. Temperature decreases
C. Pressure increases
D. Humidity decreases only
✅ Correct Answer: A. Temperature increases
Rationale
