FSX/Prepar3D skyLOGX v0.9.3.
skyLOGX is a VBA-based MS Excel spreadsheet application to ease your pre-flight workload with A2A Simulations' Cessna 172R although with slight modification in programming routine, the logic can be applied to any fixed-pitch propeller aircraft. Actually, I'm planning to release similar apps for Piper Cherokee 180 and the recently released Cessna 182 Skylane, both from A2A Simulations. Prerequisites: Microsoft Excel 2007 or higher, enabled macros, FSX/P3D flight plan (in XML format), stable Internet connection, free Time Zone API key from World Weather Online (this is basically required to ensure correct time calculations. You'll be requested to enter you API key upon the first launch of application).
