FSX & FSX: Steam Edition SDK & Development Questions & Answers

FSX development spans several toolchains, so this hub separates SDK installation and configuration from the work of building content. It covers matching the SDK to boxed FSX or Steam Edition, locating documentation and compilers, resolving failed or incomplete installs, and checking prerequisites, paths and environment settings before troubleshooting a project.

Practical topics include writing and debugging XML gauges, understanding how BGL files are compiled and stored, and establishing workable pipelines for aircraft and scenery creation. The answers also clarify where specialist modelling, texture and placement tools fit alongside the official SDK. Guidance is written and tested by the Fly Away team against real FSX development problems rather than idealised examples.
