Performance

Question 1

When should you not use a FLX take-off?

Answer 1

Medium or worse BA
Contaminated Rwy
Anti-skid off
MEL Perf restrictions
Windshear
FLX temp is lower than OAT or TREF

Question 2

What can FLX never be lower than?

Answer 2

25% reduction on full thrust
Climb thrust for same conditions
MCT Thrust
Cannot be lower than the TREF or actual OAT

Question 3

Do you need to correct TFLEXMAX like TREF?

Answer 3

No

Question 4

When doing a Dispatch Landing calculation, which rwy and wind conditions should you use?

Answer 4

Use the longest runway in still air

Then the actual planned runway in forecast conditions.

Question 5

What is the minimum Miss App acceleration altitude?

Answer 5

1000ft above airfield if AEO, Initial GA altitude if OEI.
Can change this if you think you will miss the TOGA limit.
Also think about increasing this for Windshear and Circling approaches

Question 6

If using the Go-around charts what altitude should you use when looking for a weight?

Answer 6

The mid point between the DA and the missed approach altitude, to make sure it covers the whole missed app.
