`flightgear-python` is an interface package to the [FlightGear flight simulation software](https://www.flightgear.org/) aimed at simplicity.

Install: `pip3 install flightgear-python`

Flight Dynamics Model (FDM) example, from `examples/simple_fdm.py`
```python
"""
Simple Flight Dynamics Model (FDM) example that makes the altitude increase and the plane roll in the air.

        fdm_data['phi_rad'] = phi_rad_child  # we can force our own values
    fdm_data.alt_m = fdm_data.alt_m + 0.5  # or just make a relative change
    return fdm_data  # return the whole structure

"""
Start FlightGear with `--native-fdm=socket,out,30,localhost,5501,udp --native-fdm=socket,in,30,localhost,5502,udp`
(you probably also want `--fdm=null` and `--max-fps=30` to stop the simulation fighting with
these external commands)
