This service provides customers with portable electronic flight bag (EFB) software for use in scenarios such as ground flight release and in-flight performance calculations. The service is divided into three modules: the Performance Calculation Module, the Navigation Chart Module, and the Electronic Release Module. The Performance Calculation Module provides performance calculation capabilities for mobile devices, including takeoff, in-flight, and landing performance calculations, with data sourced from PES online performance calculations and the FCOM manual performance data. The Navigation Chart Module offers electronic charts that contain the same content as paper charts, along with the capability to overlay additional layers. The Electronic Release Module provides pilots with a paperless release function, enabling them to download and view all documents offline, as well as meet the requirements for electronic signatures in advisory notices.
