MAXIMUM LEVEL-OFF HEIGHT
It is the height where the takeoff thrust time limit occurs at the end of
the acceleration segment. The maximum level-off height cannot be
lower than the minimum level-off height.
FIRST SEGMENT
Starts at 35 ft above the takeoff surface, at the end of the one-engine-
inoperative takeoff distance (TOD/OEI), and extends to the point where
the landing gear is fully retracted using a constant V
2
speed and
takeoff flaps.
SECOND SEGMENT
Extends from the end of the first segment up to the level-off height,
with takeoff flaps, gear up, and constant V
2
speed.
EX
TENDED SECOND SEGMENT
It is an extension of the second takeoff climb segment, above the
maximum level off height, to improve obstacle clearance performance.
THIRD (OR ACCELERATION) SEGMENT
Extends from the end of the second segment, at the level-off height, up
to a point where the airplane is accelerated to final segment speed
(V
FS
) while retracting flaps.
FINAL SEGMENT
Extends from the end of the third segment to a gross height at least at
1500 ft AGL, with flaps up and at final segment speed (V
FS
). The final
segment ends at 3000 ft AGL for the CAFM.
WEIGHTS
REGULATED TAKEOFF WEIGHT - RTOW
It is the maximum allowed takeoff weight at the start of takeoff run,
derived by complying with all requirements, such as those related to
field length, climb gradients, brake energy, tire speed, obstacle
clearance and structure.
TAKEOFF WEIGHT - TOW
It is the gross weight of the airplane at the start of takeoff run.
