Generally speaking, how accurate is POH takeoff ground roll data? Here's my situation - taking four people (myself included) on a short trip on Sunday in my 172P. We'll be taking off at max gross and landing at a field with a short strip (2,300ft). My takeoff roll calculations (with expected density altitude) come to about 1,500 feet according to the book (excluding wind).
The only other times I've taken off at max gross were during periods of cooler weather - this will be at around 87 degrees. Part of me says just to trust the numbers, but for some reason I still have some uncertainty. How much should I trust the book? A/C is a 1982 model - 160hp BTW.
Thanks in advance
