FCOM: 20/2 - Limitations (director's cut)

Question 1

MZFW A319?
MZFW A320?
MZFW A321?

Answer 1

57 tonnes
62.5 tonnes
73.3 tonnes

Remember:
“Z” in ZFW looks like a 7 or 2.
“320” has a 2 in it, and if you add 3 and 2 you get 5.
321: add 2+1= 3, so 3/3 (73.3)

Question 2

MLW A319?
MLW A320?
MLW A321?

Answer 2

61 tonnes (9-3=6. Add a “1” and it becomes 61)
66 tonnes (Neo = 66.3 tonnes) (3x2 = 6)
77.3 tonnes (3x2+1 = 7)

Answer 3

A319:
64/66/68 depending on certification

A320:
73.5/75.5/77 (+ 79 for NEO) depending on certification

Question 6

What is the maximum taxi weight?

Answer 6

400kg higher than MTOW

01/11/24

Question 7

Minimum pavement width for a 180° turn?

Answer 7

22.8m for A320.

This is based on the offset between the outboard main gear and the nose gear.

So, YES you can turn on a 30m wide runway. However, the following considerations must be made:
- slow continuous turning
- symmetrical thrust
- no differential braking
- dry surface.

Question 8

When the aircraft has been fuelled to maximum capacity, what temperature rise is acceptable before the fuel will start spilling out?

Answer 8

20°C.
This equates to about 2% expansion.

Question 9

Absolute service ceiling (pressure altitude in feet)?

Answer 9

39,800ft

Question 10

Max crosswind “slippery wet” for take off?

Answer 10

25kt (per OMB)

01/11/24

Question 11

What are the limitations for OETD?

Answer 11

SLoPY

• Slippery taxiways
• LVPs in force
• Powerpush via the main landing gear
• Y ELEC PUMP fully serviceable

Question 12

What are the normal engine idle parameters after engine start? (EGT)

Answer 12

EGT: 725°C (CEO), 750°C (NEO)

Question 13

What is the normal range of oil pressure?

Answer 13

30-80psi (CEO)

Question 14

How long does a BCF Fire Extinguisher last for?

Answer 14

15 seconds

Question 15

Maximum tyre speed?

Answer 15

195kt

Question 16

When viewed from the front, which way to the engine fan blades rotate?

Answer 16

Anticlockwise (both ENG 1 & 2)

Question 17

What is the cockpit window speed limit?

Answer 17

200kt

01/11/24

Question 17

Taxi speed with one tyre deflated?

Question 18

Maximum and minimum cabin pressure differential?

Answer 18

-1.0 PSI to +9.0 PSI
Safety relief valve will open at +8.6 PSI

01/11/24

Question 19

What is the minimum runway width permissable?

Answer 19

30m

01/11/24

Question 20

Maximum wind speeds for doors?

Answer 20

NB these are the speeds for door OPERATION, not maximum “door open” speeds:
Passenger door - 65kt
Cargo doors - 40kt

Cargo doors must be closed before wind speeds exceed 65kt.

Question 21

Maximum crosswind for starting a NEO engine?

Answer 21

45kt

01/11/24

Question 22

Maximum taxi speed with deflated or damaged tyres

Answer 22

7kt if one tyre is deflated per gear
3kt if you have 2 deflated tyres on any gear
Maximum nosewheel deflection with any deflated tyre is 30°.
