44.51m

Question 2

How many seats?

Answer 2

230

Question 3

What is the engine thrust?

Answer 3

33 000lb of thrust

Question 4

MTOW?

Answer 4

93 000kg

Question 5

How do wing dimensions compare to A320?

Answer 5

Same- which means a higher wing loading.

Question 6

MLW?

Answer 6

77 800kg

Question 7

MZFW?

Answer 7

73 800kg

Question 8

Minimum runway width for 180 deg turn?

Answer 8

32m- A321 operations not permitted on 30m runways.

Question 9

What does ECON flow pb do (if fitted)?

Answer 9

ON: ECON flow is selected (less than 167 pax)

OFF: normal flow is selected. Normal flow provides 20% more than ECON flow.

Manual selection not available during single pack or with bleed supplied by APU. In the cases high flow- 40% more than ECON flow.

Question 10

In what config are CAT II and CAT III fail passive autoland approved?

Answer 10

Configuration 3 and full.

Question 11

Forward and aft cargo detectors and loops?

Answer 11

Forward: 4 detectors (2 compartments) linked to 2 detection loops.

Aft: 6 detectors (3 compartments) linked to 3 detection loops.

Question 12

Flap extension speeds A321 CEO?

Answer 12

1: 235
1+F: 225
2: 215
3: 195
Full: 190

Question 13

When will speed brakes auto retract in the A321?

Answer 13

Config 3 and Config FULL (versus A320 Conf FULL only)

A321 FULL speedbrake available in both manual and automatic flight.

Question 14

What fuel tanks does A321 have?

Answer 14

Centre and Wing tanks only (no inner/outer).

Centre tank uses jet pumps to transfer fuel into each wing tank.

Question 15

What sequence do A321 fuel tanks feed?

Answer 15

-centre tank; fuel transfers into the wing tanks (after 250kg used from the wing tanks)

-wing tanks

Question 16

When does low fuel memo appear in A321?

Answer 16

Fuel quantity in either wing is below 1500kg.

Question 17

When fuel is gravity fed from centre tank to wing tanks, why is 2000kg unusable?

Answer 17

This assists in a forward CG.

Question 18

What engines are on A321 and thrust??

Answer 18

IAE V2533-A5

33 000lb thrust

Question 19

A321 starting temp limit, toga time limits and max continuous?

Answer 19

Starting: 635 deg

Toga: 650 deg (5min)

1 inop: 650 (10min)

Max cont: 610 deg

Question 20

What is the purpose of auto flap retraction on A321?

Answer 20

At heavy takeoff weight, S speed may be higher than MAX speed for config 1+F (225kt).

Continue to accelerate and at 210kt auto flap retraction will occur and MAX speed will move to 235kt.

Question 21

What is a risk of speed brake extension with high wing loading in A321?

Answer 21

VLS may increase above the target speed

Question 22

At high weights during deceleration, green dot can be above Vfe next. How can Conf 1 be selected?

Answer 22

Selected a lower. Eg. If green dot is 235kt, select 225kt.

Question 23

A321 tailstrike- pitch attitude awareness:

Answer 23

Landing gear not compressed- 11 deg
Landing gear compressed- 9.5 deg

Question 24

On A321 CEO, does final landing config provide a margin above VLS?

Answer 24

Only on sharklet aircraft- 5kt margin on PFD.

On non-shark jet aircraft if speed additives not already applied to PERF APPR, 2-3kt can be added to restore margin.

Question 25

Turbulence penetration speed?

Answer 25

275kts to 20000ft,
305kts into 0.76.
