gallaxy flyer - for a long time that was my assumption as well that Cessna providing required takeoff distance includes ASDR in its computation but recently came to conclusion that this is not so. Assume you accelerate to Vr which happens to be V1 as well and then you decide to aboard. There is no way in this world you will convince me that distance it takes to climb just 35 feet from that rotation point is the same as stopping fully loaded plane from such high speed. It takes me perhaps (Im guessing) 3 seconds to climb to 35 feet. So you try to convince me I will stop in approximately the same time ? No way my friend !
