Ultra Light Performance Tool (ULPT) is an Open-Source-Project meant for takeoff performance calculations for ultra light aircraft.

This very version is published by Worldpixel Software and is proprietary and closed as such. It is almost completely based on the open source variant of ULPT and varies only by some changes necessary for store publication.
