=== -set.xml === | |||
Call the Nasal file in your aircraft's -set.xml file by adding the following code inside <nasal></nasal> | |||
<syntaxhighlight lang="xml"> | |||
<fbw> | |||
<file>Aircraft/787-8/Nasal/fbw.nas</file> | |||
</fbw> | |||
</syntaxhighlight> | |||
Replace '787-8' with your aircraft folder name. | |||
=== JSBSim FDM === | |||
Replace 'aileron-cmd-norm' with 'aileron-fbw-output'. | |||
Replace 'elevator-cmd-norm' with 'elevator-fbw-output'. | |||
Finally, replace 'rudder-cmd-norm' with 'rudder-fbw-output'. | |||
== Configuration == | |||
Add the following switches anywhere (preferably the CDU) to be able to configure the CDU in FlightGear: | |||
* /controls/fbw/active (controls whether the fly-by-wire system is active or not) | |||
* /controls/fbw/yaw-damper (controls the yaw damper) | |||
* /controls/fbw/rudder (controls whether the fly-by-wire controls rudder or not) | |||
* /controls/fbw/bank-limit (controls the aircraft's bank limit) | |||
If you don't want any of the configurations to be edited in Flightgear, but configured generally, add the following under </sim> to your -set.xml for the appropriate properties you want to configure: | |||
<syntaxhighlight lang="xml"> | |||
<controls> | |||
<fbw> | |||
<yaw-damper type="int">1</yawdamper> | |||
<rudder type="int">1</rudder> | |||
<bank-limit type="int">30</bank-limit> <!-- 30 degrees bank permitted --> | |||
</fbw> | |||
</controls> | |||
</syntaxhighlight> | |||
