FrankenTurb - it goes bump in the night and jiggles your bum

[macroflight]

This addon downloads free terrain elevation and wind data from the Internet. This is then used to determine if the current PSX position would be affected by any wind-generated turbulence of the following types:

- Mechanical (orographic) turbulence (wind blowing over uneven terrain)
- Mountain wave turbulence
- Lee rotor
- Wind shear CAT (e.g when entering a jet stream)

If turbulence is warranted, it injects random WxBurst events into PSX. WxBurst type (sink, gust, roll, speed, ...) and intensity is influenced by the turbulence type and intensity.

In addition, it uses CB locations from the PSX weather radar and generates turbulence in and around these.

A CDU interface lets you turn the system on and off as well as adjust the individual intensity of the various types of turbulence. The CDU display also shows some details about what kind of turbulence is being generated and its intensity. More details are printed in the addon output window, e.g "mountain wave generated by terrain elevation 8200 feet bearing 320 degrees distance 23 nm"

For testing you can also enable (command line option --acceleration) a connection to a PSX boost server. The addon window will then display the current aircraft acceleration in all axes. The use of this feature to perfect your barrel rolls is strictly prohibited

Download from GitHub or for those that don't want to instyall Python EXE files are available

This code was developed from scratch using Claude.ai. It does not use any existing turbulence addon code. Everything is either standard textbook physics, published ICAO/FAA criteria (public domain), or simple empirical engineering invented for this project. There are no patents involved — mountain wave and orographic turbulence theory has been in the public domain for 75+ years.

The wind and terrain data sources (Open-Meteo CC-BY 4.0, Copernicus DEM) are to the best of my knowledge freely available for non-commercial use.
