About

Ultra Light Performance Tool

Read full description

Ultra Light Performance Tool (ULPT) is an Open-Source-Project meant for takeoff performance calculations for ultra light aircraft. It was created by a team of flight instructors and software developers aiming to give new pilots an idea of how certain environmental conditions may affect the performance of their aircraft during takeoff. 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. Features: •Add Aircraft and Airports with respective data •Calculation of factorized takeoff distance for ultra light aircraft •Calculations based on Flugsicherheitsmitteilung (Flight Safety Letter) FSM 3/75 of the LBA (German Civil Aviation Authority) as well as AOPA Safety Letter June 2020 Project Website: https://github.com/FrenchTacoDev/ultra_light_performance_tool
