Segment 3 performance - 20.7.1b
Did a search and could not find the answer; hoping someone can help.
This relates to the Australian CAOs, in particular 20.7.1.b, which deals with takeoff climb performance.
Firstly, my understanding is that in the third (level) segment, a climb performance capability of 1.2% gross is required and that this capability is available to accelerate the aircraft in that segment to final takeoff climb speed. (I'm paraphrasing 7.3.1 and 7.3.2)
However, I just noticed a sentence in the orders that I don't understand.
7.5 "...Similarly the horizontal distance to accelerate in compliance with paragraph 7.3.1 must be increased due to the acceleration reduction equivalent to the climb gradient reductions specified in this paragraph."
I'm not even sure I understand that sentence at all, but if I interpret it correctly:
1) Firstly, how can the horizontal distance to accelerate in the level segment be determined at all?
and
2) How could that distance (if able to be determined) be reduced by an allowance based on a climb gradient reduction from gross to net -a "reduction equivalent" -if in fact that is what it means...
Confused I am.
