Take Off Criteria for Boeing NG A/C?
I was told that on Boeing NG A/C, there was a trade off during certification of Take Off Performance:
For a lower screen height - 10' instead of 35' - Boeing NG A/C must use WET Take Off numbers when the runway is wet - rather than those numbers being "advisory." Skid resist plays a part here also - but for now I'd like to limit this discussion to just having wet or dry available.
Don't have the official AFM with me now and it won't give the reasons anyway.
BTW - got lot's of opinions on this - it was discussed in a bar - would like responses with references if possible.
Thanks for any factual information that can be provided,
