Question 1

Takeoff and Go-around Thrust Setting Time and EGT Limits - All Engines Operative

Answer 1

20s / 920 °C &
5 min / 900 °C

Question 2

Takeoff and Go-around Thrust Setting Time and EGT Limits - One engine inoperative

Answer 2

10 min / 900 °C

Question 3

Engine Start On Ground EGT Limit

Answer 3

700 °C

Question 4

Engine Start Inflight EGT Limit

Answer 4

850C

Question 5

Maximum Engine N1 Shaft Speed (%)

Answer 5

99%
The N1 limit depends on the ambient conditions and on the configuration of the engine air bleed.
These parameters may limit N1 to a value that is less than the above-mentioned N1 value.

Question 6

Maximum Engine N2 Shaft Speed (%)

Answer 6

103%

Question 7

Maximum Engine N3 Shaft Speed (%)

Answer 7

100%

Question 8

Maximum continuous oil temperature

Answer 8

190C

Question 9

Minimum oil temperature before takeoff

Answer 9

50C

Question 10

Minimum Oil Quantity

Answer 10

The minimum oil quantity is the highest value of:
15 qt, or
6 qt + estimated consumption.
Average estimated consumption = 0.7 qt/h.

Question 11

Minimum oil pressure

Answer 11

25 PSI

Question 12

Engine Starter Limitations

Answer 12

Starter maximum continuous operation is 5 min.

Two 3 min duty cycles and a consecutive 1 min cycle is permitted with run down to zero N3 between each cycle.

After one continuous operation, or the three cycles wait 30 min to allow the starter to cool.

No running engagement of the starter when the N3 is above 10 % on ground, or 30 % in flight.

Question 13

Speed below which Maximum reverse should not be used

Answer 13

70kts

Question 14

FLEX Takeoff Restrictions

Answer 14

FLEX takeoff is not permitted on contaminated runways.
