Return to top of page Take-off distance calculator A phase of flight may have multiple charts. So now take your normal takeoff speed, and add that difference for your Vlof normal. The total energy is the sum of mass times speed change squared divided by two, weight times elevation gained (or lost) from runway slope and weight times the height when the take-off is complete. Draw another line horizontally from the point of interception, to the next Reference Line. So it requires a little more than just a rote application of the 70/50 calculation.
