POWERPLANT LIMITATIONS QUESTIONS

Question 1

What is the minimum engine oil quantity for each flight?

Answer 1

As specified in PRO-NOR-SOP

Question 2

What is the minimum oil temperature for
takeoff?

Answer 2

A320ceo, A321ceo : +50 deg C
A321neo : +19 deg C

Question 3

What is the maximum time limit for using
TOGA thrust?

Answer 3

5 Minutes under normal conditions
10 Minutes in case of engine failure

Question 4

What is the max. EGT for any phase?

Answer 4

The red line limit on the EGT scale

Question 5

What are the engine starter limitations for the A320 fleet?

Answer 5

• A standard automatic start that includes only one start attempt is considered one cycle. (A321neo: Up to three start attempts is considered one cycle.)
• For ground starts (Auto or manual) pause 15 secs between successive cycles. (A321neo: A 60s pause is required between successive cycles.)
• After 3 failed start attempts or 5 min of continuous crank allow a 30 min cooling period. (A321neo NEO: 15 min cooling period required subsequent to three failed cycles.)
• For manual starting observe a 2 min maximum cycle time (Only CEO aircraft)
• Maximum crank time is 5 min (Only CEO aircraft)
• The starter must not be run when N2 is above 10% on ground and 18% in flight. (A321neo NEO: The starter must not be run when N2 is above 63%)

Question 6

What are the limitations regarding the use of Reverse Thrust?

Answer 6

1. Selection of reverse thrust in flight is prohibited.
2. Backing with reverse thrust is not permitted.
3. Maximum reverse should not be used below 70 knots.
4. Idle reverse is allowed down to aircraft stop.

Question 7

Is reduced thrust take-off allowed on
contaminated runways?

Answer 7

No

Question 8

Is reduced thrust take-off allowed with
inoperative aircraft systems or components that affect performance?

Answer 8

Yes, provided the associated performance shortfall has been applied to meet all performance requirements.
