===.xml=== | |||
In the FDM file we have to add the pushback engine. | |||
<engine file="pushback"> | |||
... | |||
After the </propulsion> tag we add a reference to the pushback system: | |||
<system file="pushback"/> | |||
===-set.xml=== | |||
Between the <model> tags in the -set.xml file we set two properties to false (0). | |||
<model> | |||
<pushback> | |||
<magnitude>0</magnitude> | |||
<linked>0</linked> | |||
</pushback> | |||
</model> | |||
Below the </sim> tag we add our keyboard bindings: | |||
<keyboard> | |||
<key n="43"> | |||
<name>+</name> | |||
<desc>Pushback Magnitude increase</desc> | |||
<repeatable type="bool">true</repeatable> | |||
<binding> | |||
<command>property-adjust</command> | |||
<property>/sim/model/pushback/magnitude</property> | |||
<max type="double">40000</max> | |||
<step type="double">20000</step> | |||
</binding> | |||
</key> | |||
<key n="45"> | |||
<name>-</name> | |||
<desc>Pushback Magnitude decrease</desc> | |||
<repeatable type="bool">true</repeatable> | |||
<binding> | |||

<min type="double">-40000</min> | |||
