takeoff segments
Hi guys,
I'm a sport pilot, new on this forum. Hope you can help me with this question: which one of the 4 takeoff segments is the critical one and why? Thanks in advance to everybody

In terms of raw climb gradient requirements per part 25, 2nd segment has the steepest OEI minimum gradient. In actual operations, obstacle clearance requirements dictate. Sometimes 1st segment will be the most limiting due to close in obstacles in the takeoff path.

Does it really matter ? At the end of the day one has to run through a bunch of requirements and that which is most critical on the day becomes the limiting consideration. Tomorrow from a different runway and it may well be quite different.
Different aircraft have their little foibles and it probably doesn't work all that well trying to put all into the one basket.

Back in the Dino days when the FE crunched the numbers it probably mattered more. Runway limited? Try more flaps. Climb limited, try less flaps and a longer runway. Now with so much data being based on "optimum" and being spit out on ACARS the true limit is just a footnote in the paperwork.
