flightgear_python.fg_if.FDMConnection

class flightgear_python.fg_if.FDMConnection(fdm_version=None, rx_timeout_s=2.0)

Bases: FGConnection

FlightGear Flight Dynamics Model Connection

Parameters:

fdm_version (int | None) – Net FDM version (24, 25, or None for auto-detection)
rx_timeout_s (float) – Optional timeout value in seconds when receiving data

__init__(fdm_version=None, rx_timeout_s=2.0)

Parameters:

Methods

`connect_rx`(fg_host, fg_port, rx_cb)	Connect to a UDP output of FlightGear
`connect_tx`(fg_host, fg_port)	Connect to a UDP input of FlightGear
`start`()	Start the RX/TX loop with FlightGear
`stop`()	Stop the RX/TX loop

Attributes

`fg_auto_partial_parse`
`fg_net_struct`

connect_rx(fg_host, fg_port, rx_cb)

Connect to a UDP output of FlightGear

Parameters:

fg_host (str) – IP address of FG (usually localhost)
fg_port (int) – Port of the output socket (i.e. the 5501 from --native-fdm=socket,out,30,localhost,5501,udp)
rx_cb (Callable[[Container, EventPipe], Container | None]) – Callback function, called whenever we receive data from FG. Function signature should follow rx_callback_type

Returns:

EventPipe so that data can be passed from the parent process to the callback process

Return type:

EventPipe

connect_tx(fg_host, fg_port)

Connect to a UDP input of FlightGear

Parameters:

fg_host (str) – IP address of FG (usually localhost)
fg_port (int) – Port of the input socket (i.e. the 5502 from --native-fdm=socket,in,30,localhost,5502,udp)
