200 VERIFIED Q&A | AIRBUS TECHNICAL
STUDY GUIDE | A+ TOP RATED
A321 KSV Technical Validation Exam
1. What is the maximum operating altitude for the Airbus
A321?
A. 37,000 ft
B. 39,100 ft
C. 41,000 ft
D. 43,000 ft
Answer: B
Rationale: The certified maximum operating ceiling for the A321 series
is 39,100 feet. Exceeding this altitude violates structural and
pressurization safety margins.
2. Which of the following is the maximum takeoff crosswind
component (including gusts) for the A321?
A. 25 knots
B. 29 knots
C. 35 knots
D. 40 knots
Answer: C
Rationale: 35 knots is the maximum demonstrated crosswind for
takeoff. This is a limitation for flight stability and directional control on
the runway.
3. The A321 flap system differs from the A320 because the
A321 uses:
A. Single-slotted flaps
B. Double-slotted flaps
C. Triple-slotted flaps
D. Variable-camber flaps
Answer: B
Rationale: To provide the necessary lift for its heavier fuselage, the
A321 utilizes double-slotted flaps, which distinguishes its approach
handling from the A320.
,4. What is the maximum landing gear extension speed (VLO)?
A. 220 knots
B. 250 knots
C. 280 knots
D. 300 knots
Answer: B
Rationale: VLO (extension) is limited to 250 knots to prevent excessive
aerodynamic loads on the gear doors and actuation mechanisms.
5. In the event of a total electrical failure, the Ram Air Turbine
(RAT) provides hydraulic pressure to which system?
A. Green
B. Yellow
C. Blue
D. All three
Answer: C
Rationale: The RAT is designed specifically to pressurize the Blue
hydraulic system, which then powers the Emergency Generator and
flight controls.
6. At what temperature should the Brake Fans be turned off to
ensure accurate cockpit readings?
A. 150°C
B. 300°C
C. 100°C
D. 50°C
Answer: A
Rationale: Brake fans should be turned off when the temperature
reaches 150°C to ensure the temperature indicated on the ECAM reflects
the actual internal heat of the brake assembly.
7. The Power Transfer Unit (PTU) automatically runs when the
differential pressure between the Green and Yellow systems is
greater than:
A. 300 PSI
B. 500 PSI
C. 1000 PSI
D. 1500 PSI
Answer: B
Rationale: The PTU is a bidirectional pump that allows one system to
pressurize the other without mixing fluids when a 500 PSI delta is
detected.
,8. What is the maximum altitude for APU start using battery
power only?
A. 20,000 ft
B. 25,000 ft
C. 35,000 ft
D. 39,100 ft
Answer: B
Rationale: While the APU can run at 39,100 ft, a battery-only start is
limited to 25,000 ft due to the lower air density and battery discharge
rates at altitude.
9. "Alpha Floor" protection is an autothrust function that
commands:
A. Idle thrust
B. Maximum Continuous Thrust (MCT)
C. TOGA thrust
D. Descent
Answer: C
Rationale: Alpha Floor is a predictive protection that applies TOGA
thrust regardless of lever position when the aircraft reaches a critically
high Angle of Attack.
10. On the A321, how many Additional Center Tanks (ACTs)
can typically be installed?
A. None
B. Up to 2
C. Up to 4
D. Only 1
Answer: B
*Rationale: The A321 configuration allows for up to 2 ACTs in the
cargo holds to extend range; some specialized variants like the A321LR
can carry up to 3.
11. The maximum tire speed for the A321 is:
A. 185 knots
/B. 195 knots
C. 205 knots
D. 225 knots
Answer: B
Rationale: 195 knots ground speed is the structural limit for the tires.
Exceeding this during a high-speed takeoff can lead to tire
disintegration.
, 12. Which engine failure protection is active during takeoff to
prevent a Dutch Roll?
A. Alpha Floor
B. Yaw Damper
C. Ground Spoiler
D. Automatic Pitch Trim
Answer: B
Rationale: The Yaw Damper provides turn coordination and Dutch Roll
damping, which is critical during asymmetric thrust conditions like an
engine failure.
13. What is the maximum EGT for a LEAP-1A engine during a
standard takeoff?
A. 950°C
B. 1010°C
C. 1060°C
D. 1100°C
Answer: C
Rationale: For the A321NEO (LEAP-1A), 1060°C is the typical transient
limit for takeoff. Exceeding this requires an engine inspection.
14. The APU bleed air may be used for a "Dual Pack" operation
up to:
A. 15,000 ft
B. 20,000 ft
C. 22,500 ft
D. 25,000 ft
Answer: B
Rationale: APU bleed air capacity diminishes with altitude; dual pack
operation is limited to 20,000 ft, whereas single pack is permitted to
22,500 ft.
15. When using the Autobrake in "MAX" mode, when does the
pressure start to apply?
A. 2 seconds after ground spoiler extension
B. Immediately upon main gear touchdown
C. Immediately upon ground spoiler extension
D. Only when the pilot presses the pedals
Answer: C
Rationale: On the A321, MAX autobrake (used for takeoff) applies
pressure as soon as the ground spoiler deployment signal is received to
maximize stopping distance.
