Question 0

A321 engines

Answer 0

CFM 56-5 engines

Question 1

A320-A321 flap slat comparison speeds

Answer 1

A320. A321
230. Slats 1 235
215 Slats1/flaps1 225
200. Flaps2 215
185. Flaps3 195
177. Flaps Full 190

Question 2

Dimensions of A321

Answer 2

Length 146’ (23’ longer than A320)
Wingspan 111’10”
Height 39’11”

Question 3

Pax seats

Answer 3

230

Question 4

Geometric limits of pitch

Answer 4

Rotation for Takeoff max pitch 8.5*
Max pitch for landing 6.6* (audible call out is at 7.5)
Clearance 9.7 in A321 (11.7* in A320)

Question 5

Turn clearance

Answer 5

Unlike the 319/320 the turn radius constraint is the tail clearance
81 feet from turn side main gear to tip of tail nose steering at Max of 75degrees
Nose clearance from tip nose to mains is 74 feet
Overhang of nose tip to nose gear is 5.3 feet
Differential power setting 50-55% N1

Question 6

Air conditioning differences

Answer 6

Pack flow button of 319/320 is replaced by an “Econ flow” button.
Econ flow “on” position economy flow selected
In “off” position pack flow is 20% greater in this “normal” position

Question 7

Fuel capacity

Answer 7

Total capacity is 41000 lbs
Inner tank 14200 lbs
Outer tanks (2) 13400 lbs each

Question 8

Fuel tank/pump differences

Answer 8

No separate outer wing tanks
No direct feed from center tank to engines
No center tank pumps (replaced with motive flow jet pumps)
Therefore in emergency configuration, the left and right pumps in wing tanks remain available.
Transfer valves feed the outer tanks from center tank

Question 9

Thrust bump active when

Answer 9

Either Thrust bump button is pushed
Engine core speed above 50%
Temp is ISA+15 at sea level
Thrust levers moved beyond FLX/MCT position
Remains active entire flight unless button pushed again PRIOR to takeoff

Question 10

Deactivation of thrust bump occurs when

Answer 10

• Thrust bump button pressed a second time prior to takeoff power being added (below FLX/MCT )
• when aircraft is on the ground for 30 seconds after touchdown

Question 11

Max takeoff weight A321
Max takeoff weight A320
Max takeoff weight A319

Answer 11

A321 is 206,130 lbs MTOW
A320 is 169,755 lbs MTOW
A319 is 154,320 lbs MTOW

Question 12

Max zero fuel weight
A321
A320

Answer 12

A321 is 162,699 lbs MAXZFW

A320 is 137,788 lbs MAXZFW

Question 13

Max landing weight
A321
A320
A319

Answer 13

A321 is 171,518 lbs MLW
A320 is 145,505 lbs MLW
A319 is 134,480 lbs MLW

Question 14

Max wind components

Answer 14

Landing crosswind 38 Knots dry 
33 knots wet 
10 knots contaminated 
10 kts tailwind  takeoff (A319/320 is 15kts )
Landing 10kts tailwind
