Good evening. The segments for certification apply to all current transport category aircraft, 2 engines or more.
I'll use a dry runway reference:
Reference zero is 35 feet, gear down.
First segment starts at Reference zero, ends when the gear is retracted.
Second segment is flown at V2, gear up, flaps in takeoff configuration and ends at the acceleration height.
Third segment is flap retraction, conducted normally at takeoff thrust and ends when the aircraft is clean and at max continuous thrust.
Final, or fourth segment is enroute climb, clean and at enroute climb speed, single engine.
Does this fit the bill?
