Xplane MFD Calculations

This repository contains flight calculation code for data published by the X-Plane Web API. It demonstrates the Joint Strike Fighter Air Vehicle C++ Coding Standards (JSF AV C++). The compliant/ directory contains code with numerous JSF Standard fixes, while non-compliant/ contains multiple major standard violation examples.

The main non-compliant code examples are marked with REMOVE BEFORE FLIGHT tags showing violations with:

1. Exceptions — AV Rule 208
2. Recursion — AV Rule 119
3. Dynamic Memory Allocation — AV Rule 206

Build

# Build JSF-compliant version (default)
make

# Build non-compliant version
make non-compliant

Run

# Launch the MFD (requires X-Plane with Web API)
./run_mfd.sh
