My first multi-platform open-source App on Kotlin for Desktop & Android.Application helps to control, proceed and complete checklists of virtual airplanes as well as calculate fuel quantity for your trip and get METAR/TAF with visualized wind director.* App uses its own airports database with more than 76 thousand airports. It should be downloaded and converted for the first use or update and takes about 40 Mb of the memory.* New feature - QFE Helper!You can easily convert QFE air pressure given you by ATC to QNH for modern aircrafts which do not support QFE. Also feature allows you to convert Height given in meters AGL (above ground level) to feet ASL (above sea level). At present checklists are implemented for Cessna 172 Skyhawk, the most popular general aviation in any simulator, Cirrus SR-22, the luxury one, and Cessna Citation X from X-Plane 12.Get the Desktop version at github: https://github.com/alexmaryin/sims_checklist/releasesGlad to see you soon in virtual skies!
