  "text": "After the segmented flight path has been derived according to the procedure described in Section 2.7.13 and the sub-segmenting described is applied, further segmentation adjustments may be necessary. These include\nthe removal of flight path points which are too close together and\nthe insertion of additional points when speed changes along segments are too long.\nWhen adjacent points are within 10 metres of each other, and when the associated speeds and thrusts are the same, one of the points shall be eliminated.\nFor airborne segments where there is a significant speed change along a segment, this shall be subdivided as for the ground roll, i.e.\nn seg = int 1 + V 2 − V 1 ∕ 10\n(2.7.16)\nwhere V1 and V2 are the segment start and end speeds respectively. The corresponding sub-segment parameters are calculated in a similar manner as for the takeoff ground roll, using equations (2.7.11) to (2.7.13).",
