you are rolling out after touchdown and decide you really need to abort your landing, and takeoff. your airplane is at 116 knots and your engines have spooled down to 71% idle. you need a v2 of 142 to safely lift off and climb. the airplane will require 6 seconds to accelerate after the engines spool up to takeoff thrust, which requires 4 seconds. how much runway will you require for a safe landing abort from your decision point? (use an average of 129 knots ground speed.)
