The takeoff data isn't just calculated to get you airborne in the TODA, its also pretty damn important to clear obstacles as well in the takeoff path Engine out.
Exactly right. There is way more to TO Performance than just runway length that most pilots don't understand (myself very much included).
If I don't have intersection data I don't take off from the intersection, as pilots we just don't know what else is a factor.
What I do know is that you are changing your net take off flight path bring in factors that might not be relevant with a full length take off, therefore specific figures for the intersection should be used.
mebur_verce, thank you for that. Good to get some cold hard facts around here!
