Engine start up to 20.000ft
One pack up to 22.500 ft
Two packs up to 15.000 ft
(Air bleed extraction for Wing Anti ice is not permitted)

4 consecutive cycles lasting a max of 2 min each, 20 sec pause in between of cycles, cooling period of 15 min after 4 start attempts. No starter engagement when N2 above 20%

Question 18

Max Flex temp for A319?

Answer 18

ISA+60C (to ensure thrust reduction does not exceed 25% of full rated thrust)

Question 19

Max FLEX temo for A320?

Answer 19

ISA+53C, to ensure thrust reduction does not exceed 25% of full rated thrust

Question 20

Max allowed fuel imbalance at take off for A319/A320 incl.sharklets

Answer 20

Heavier tk - Lighter tk
Outers balanced, inners: -one full, one 500kg less
-3000kgs, 1050 kg less
-1450 kgs, 1450 kgs (may be empty)
Linear interpolation between above values.

Outer tanks for take off: max allowed imbalance - 370 kgs

Question 21

Max allowed fuel imbalance for A319/A320 incl.sharklets in flight and at landing?

Answer 21

Heavier tk - lighter tk
Outers balanced, inner tanks: full (5435) - 1500 kg
4300 kg - 1600 kg
2250 kg - 2250 kg (empty)
Linear interpolation between above values.

Outer tanks imbalance in flight and landing is allowed one full/one empty (690kg imbalance), provided L wing fuel=R wing fuel
OR
In the wing of lighter outer tank, inner tank is heavier than opposite inner tank by not more than 3000 kg

In exceptional conditions (e.g. Fuel system failure) this values, may be exceeded. Aircraft will remain fully controllable in all phases of flight

200kts

Question 27

Max taxi speed?

Answer 27

If heavier than 76t do not exceed 20 kts in turn

Question 28

What are your actions if tire damage is suspected?

Answer 28

An inspection if tires is required before taxi (LIM-LDG-BRAKES) If tire is deflated BUT not damaged, taxi slowly at low speed: - one tire deflated in one or more gear (max 3) max speed 7 kts in turn - two tires deflated on one and same main gear, other main gear not deflated, max speed 3 kts and nw strg limited to 30 degrees
