Rationales.
ATPL QUESTION BANK
Questions 1–30
Question 1
What primarily determines lift in steady, level flight?
A. Aircraft color
B. Angle of attack
C. Engine thrust
D. Weight distribution
Correct Answer: B
Rationale:
Lift is mainly controlled by angle of attack, which determines airflow and pressure difference over
the wing.
Question 2
What happens to stall speed when bank angle increases?
A. Decreases
B. Remains constant
C. Increases
D. Becomes zero
Correct Answer: C
Rationale:
Increased bank angle increases load factor, which raises stall speed.
Question 3
Which speed represents best angle of climb?
A. Vx
B. Vy
,C. Vref
D. Vlo
Correct Answer: A
Rationale:
Vx gives the greatest altitude gain per distance.
Question 4
What is the purpose of balanced field length?
A. Optimize cruise performance
B. Ensure equal takeoff and landing distance
C. Ensure accelerate-stop equals accelerate-go distance
D. Reduce braking distance
Correct Answer: C
Rationale:
Balanced field length ensures safe takeoff with an engine failure at V1.
Question 5
What does Mach number represent?
A. Speed relative to the ground
B. Speed relative to air density
C. Ratio of TAS to local speed of sound
D. IAS corrected for altitude
Correct Answer: C
Rationale:
Mach number is the ratio of true airspeed to the speed of sound.
Question 6
Which phenomenon causes Mach tuck?
A. Forward movement of the center of pressure
B. Rearward movement of the center of pressure
C. Increased lift coefficient
D. Reduced drag
Correct Answer: A
Rationale:
Shockwave formation moves the center of pressure forward, causing a nose-down pitch.
, Question 7
Which instrument is affected by gyroscopic precession?
A. Altimeter
B. VSI
C. Directional gyro
D. Airspeed indicator
Correct Answer: C
Rationale:
Gyroscopic instruments are affected by precession and drift.
Question 8
What does QNH set on the altimeter indicate?
A. Height above ground
B. Flight level
C. Altitude above mean sea level
D. Pressure altitude
Correct Answer: C
Rationale:
QNH allows altitude to be read above mean sea level.
Question 9
Which condition most increases takeoff distance?
A. Headwind
B. Low weight
C. High density altitude
D. Cold temperature
Correct Answer: C
Rationale:
High density altitude reduces engine thrust and lift.
Question 10
What is the primary purpose of slats?
A. Reduce cruise drag
B. Increase lift at high speed
C. Delay stall at low speed
D. Improve fuel efficiency
