ASAP STAR systems provide instantaneous, accurate, and reliable takeoff/landing performance (runway analysis) and weight & balance data. With airport data and surveillance for over 20,000 runways worldwide, STAR's airport database offers analysis in even the most remote locations. Automated monthly data updates ensure that the system is always using the current data. The Flight Management screen serves as the central hub for the STAR systems. From here, the operator begins a flight by entering vital flight information, such as flight number, aircraft, flight date, and departure, arrival, and alternate airports. The operator can then move on to the dedicated Weight & Balance or Runway Analysis screens to enter the respective information and perform calculations. All of the critical results will be transferred back to the Flight Management screen, giving the operator a "snap shot" of all the necessary information needed to takeoff. The STAR systems will take the guess work out of critical weight & balance calculations. The intuitive Weight & Balance screen enables the operator to quickly and accurately perform all the necessary calculations and ensures all loading limits are met. Takeoff weight, CG, and trim tab settings are instantly produced with supreme accuracy. On the Runway Analysis screen, the STAR system produces maximum performance weights for actual atmospheric, runway, and aircraft systems conditions. By calculating for only one set of conditions, payload can be maximized without compromising safety. Maximum takeoff weights for different runways can be quickly compared, then the operator can select a specific runway to view other important data like power settings, V-speeds, stabilizer settings, and more. STAR also offers operators the ability to create their own NOTAM shortened runway, a user friendly function that allows for instantaneous, last minute calculations for changes in airport data. This eliminates the rush for obtaining last minute and shortened takeoff/landing performance, associated possible flight delays, and emergency fees. STAR is a pure self-contained solution for takeoff/landing performance. The STAR advantages will be apparent almost immediately. The user will see just how easy the system is to operate and how quickly data is calculated. However, the most important benefit will be seen later on - the cost savings STAR will provide to your operation. A major air cargo operation projected an annual savings of over $2,000,000 just in increased fuel efficiency thanks to the performance optimization that STAR provides.

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
