APG WB by Aircraft Performance Group LLC offers a comprehensive solution for runway analysis and optional weight and balance calculations on iPhone, iPod Touch, and iPad. Users can access runway analysis compliant with FARand EU-OPS requirements, along with APG engine out departure procedures. The app allows viewing and downloading of weather data (METAR, TAF, PIREP) and NOTAMS for US and International airports through the AIDAP program.

Optional weight and balance calculations consider structural, CG limitations, and performance constraints for takeoff and landing. The graphical presentation of CG envelope, position, and fuel burn enhances operational insights for pilots. It's essential to note that the application requires an internet connection, potentially incurring data charges when used on cellular networks.
