To use this calculator enter the date, time, select dragstrip, ET, and trap speed. This calculator will look up the weather information for the date you entered from the closest airport to the dragstrip you select. Based on these weather conditions the calculator will calculate the density altitude and correct the timeslip to sea level.

Don't see your dragstrip listed? Send me PM with track name, state, and track elevation. Be patient we plan to add in all the dragstrips in the USA shortly.
