Question 0

What are the minimum take off climb gradients?

Answer 0

Second segment 2.4% gross

Final segment 1.2% gross

Question 1

When may flex not be used for take off?

Answer 1

Contaminated runway

Windshear reported

Question 2

How would you calculate landing and approach climb gradients?

Answer 2

Landing - all engs, gear down and approach configuration - 3.2%.
Low VIS - 2.5% gross if DH.
Approach - SE, gear up and approach configuration - 2.1% LPC LDG.

Question 3

What does REC MAX ALT mean?

Answer 3

Provides a 0.3g buffet margin.
Aircraft will climb at 300fpm at max climb thrust.
Aircraft will cruise on flight at max cruise thrust.
Aircraft will maintain a speed above green dot and below vmo.
Max selectable alt is FL398 (0.2g buffet margin).

Question 4

What does OPT ALT mean and how is it calculated?

Answer 4

Based on cost index, weight and FMCG wind data.
Compromise between time and fuel saving.
Requires a 15 min cruise segment.
