I read in a flight magazine that in order for a plane to be able to clear the runway during take-off, a plane will need to have 70 percent of its take-off speed by the time it reaches the half-way point on the runway.I already know this to be a FACT so I am not trying prove it or trying to solve this question through the use of mathematics(it works)
The part that has me stumped is the conceptual aspect of this question.
WHY does a plane need 70% of its total take off speed by the time it reaches the halfway marker of its runway.
If anyone knows the answer to this question I would greatly appreciate the help.
