Departure segments

Question 1

what are the requirements for the first segment?

from liftoff up to the point where gear is fully retracted

Answer 1

• 2 engine positive climb in still air
• 1 engine inoperative, remaining at takeoff thrust
• landing gear in max drag
• take-off flaps
• lift off speed to v2

Question 2

what are the requirements of the second segment?

from gear retraction to the point at which the flaps and slats are being retracted

Answer 2

• 2 engine 2.4% climb in still air
• 1 engine inoperative, remaining at takeoff thrust
• landing gear retracted
• takeoff flaps
• speed= V2

Question 3

what are the requirements for the third segment?

level off height

Answer 3

• 2 engine 1.2% required still air gradient
• T/O power to MCP
• retracting flaps and slats
• acceleration to at least 1.25Vs

Question 4

when does the third segment end?

Answer 4

when the maximum time allowed for use of takeoff power expires

Question 5

what are the requirements for the final takeoff segment?

Answer 5

• 2 engine 2.1% still air climb gradient
• MCP
• clean configuration
• speed minimum 1.25Vs

Question 6

when is the final takeoff segment?

Answer 6

from the end of the third segment until the aircraft reaches 1500ft above the takeoff surface or more if required for obstacle clearance

Question 7

when will the final takeoff segment exist?

Answer 7

if thrust must be reduced to MCT before the aircraft reaches 1500ft according to regulations
