Performance

Question 1

Engine failure at most critical speed for RTO and EFATO

Question 2

What are the required climb gradients?

Answer 2

Second Segment: 2.4%
Final Segment 1.25
Gross

Question 3

Some SIDS require an ALL ENGINE CLIMB GRADIENT, this will be annotated on charts when?

Answer 3

When it exceeds 3.3% (2.5+0.8)

Question 4

When does obstacle clearance start on takeoff?

Answer 4

Begins art 35feet above the end of the takeoff distance

Question 5

By how many feet must the NET TAKE OFF PATH clear obstacles?

Answer 5

35ft

Question 6

Is wind considered on EOSID?

Answer 6

NO, the crew needs to think about this

Question 7

When do you not have to follow the EOSID?

Answer 7

Once MSA is reached or in VMC the flight crew can determine all obstacles are cleared

Question 8

What is the standard acceleration altitude?

Answer 8

800ft AAL

Question 9

When is an engine considered secure?

Answer 9

Master OFF
Or
If damaged Fire PB and Agent 1 discharged or the second agent if the fire switch remains illuminated

Question 10

What is the STD EO SID?

Answer 10

Climb on RWY track
Maintain V2 until clean - if the engine fails at a higher speed than V2 maintain but do not exceed v2+20kts
After engine secure and above acceleration alt, push to lvl accelerate and retract flaps
At green dot speed and above 1500ft aal turn to holding point

Question 11

What speed must be flown when below acceleration altitude and single engine?

Answer 11

V2 and take off flaps

Question 12

You get an engine failure in the initial climb, what do you do?

Answer 12

Join EOSID

Question 13

The engine fails whilst on the SID, what do you do?

Answer 13

Turn towards to EO Holding point

Above 1500ft a radius of 30nm is surveyed for limiting obstacles ensuring clearance for EO in the Sid.

Question 14

Optimal config for take off says config 3, what do you do?

Answer 14

Try config 2

What is the max crosswind limit for a runway notified to be SLIPPERY WET?

Answer 20

25kts

Question 21

When is a runway contaminated?

Answer 21

More than 3mm on more than 25% of one third of the runway

Question 22

How do you determine the RCR for take off?

Answer 22

Use the operational tab in DOCUNET to get the runway condition determinato table for takeoff

What is the default go-around gradient computed height?

Answer 30

1500ft

Question 31

What do you do if the required go-around gradient cannot be achieved OEI?
