Airline Transport Pilot (ATP) Verified Questions,
Correct Answers, and Detailed Explanations for
Students||Already Graded A+
1. What is the primary purpose of the pitot-static system?
A) To provide fuel flow information
B) To measure airflow over the wings
C) To provide airspeed, altitude, and vertical speed information
D) To control engine mixture
Rationale: The pitot-static system measures dynamic and static air pressure to
provide the airspeed indicator, altimeter, and vertical speed indicator readings.
2. The angle of attack is defined as the angle between:
A) The horizontal stabilizer and the fuselage
B) The chord line of the wing and the relative wind
C) The aileron and the wing
D) The fuselage and the horizon
Rationale: Angle of attack is critical for lift generation and stall awareness; it’s
measured between the wing chord and oncoming airflow.
3. Which document must a pilot always have when exercising the privileges
of a pilot certificate?
A) Airplane logbook
B) Weight and balance data
C) Pilot certificate
D) FAA regulations
Rationale: FAR 61.3 requires a pilot to carry their pilot certificate when acting
as PIC.
4. A pilot should perform a forward slip to:
A) Increase engine power
B) Lose altitude without increasing airspeed
C) Reduce stall speed
D) Perform a steep turn
,Rationale: A forward slip presents the fuselage at an angle to the relative wind,
increasing drag while maintaining descent rate.
5. What is the primary reason for using a mixture control at high altitude?
A) To increase fuel pressure
B) To reduce engine noise
C) To prevent engine roughness due to a lean mixture
D) To increase cabin pressure
Rationale: Air density decreases with altitude, requiring mixture adjustment to
maintain proper fuel/air ratio.
6. Which is the best indication of a properly functioning altimeter?
A) Needle remains at zero on takeoff
B) It indicates field elevation correctly when set to local altimeter setting
C) It shows 29.92 inHg at all times
D) It responds slowly to altitude changes
Rationale: Correct altimeter setting ensures accurate altitude readings relative
to mean sea level.
7. What is the effect of frost on an aircraft wing?
A) Increases lift
B) Reduces lift and increases drag
C) Decreases stall speed
D) Improves climb performance
Rationale: Frost disrupts smooth airflow over the wing, reducing lift and
increasing drag, which can be dangerous during takeoff.
8. The acronym “IMSAFE” used for pilot self-assessment stands for:
A) Illness, Medication, Stress, Alcohol, Fatigue, Emotion/Eating
B) Instruments, Maneuvering, Safety, Altitude, Fuel, Engine
C) Ice, Motion, Speed, Altimeter, Fuel, Environment
D) None of the above
Rationale: IMSAFE is a personal checklist pilots use to ensure fitness for flight.
9. When approaching an airport for landing without a control tower, a pilot
should:
A) Wait for ATC instructions
B) Land on any runway
, C) Use the common traffic advisory frequency (CTAF) to announce position
and intentions
D) Fly overhead and circle once
Rationale: CTAF allows pilots to coordinate landing with other traffic in
uncontrolled airspace.
10. What is the primary purpose of a VOR?
A) Measure airspeed
B) Provide weather information
C) Provide azimuth (direction) information to the pilot
D) Record flight time
Rationale: VOR is a ground-based navigational aid transmitting radials to help
pilots determine direction relative to the station.
11. Which condition is most favorable for carburetor icing?
A) High temperature, low humidity
B) Cold, dry air
C) Temperatures between 20°F and 70°F with high humidity
D) Hot and humid air
Rationale: Carburetor icing occurs in cold, moist conditions even if ambient
temperatures are above freezing.
12. In the northern hemisphere, a magnetic compass will normally indicate a
turn toward the north if:
A) Turning east from north
B) Turning south from north
C) Turning through a northerly heading
D) Flying level on a westerly heading
Rationale: The compass has errors known as turning and acceleration errors,
which are most noticeable when heading north.
13. What is the primary cause of aerodynamic stall?
A) High airspeed
B) Exceeding critical angle of attack
C) Engine failure
D) Poor visibility
