AUTOMATIC PUSHBACK FOR FLIGHTGEAR
Version 0.1.1

FILES
Nasal/autopush-README.txt this file

Nasal/autopush.nas basic pushback logic
Nasal/autopush_driver.nas pushback driver
gui/dialogs/autopush.xml GUI dialog
INSTALLATION
Only the minimal working example is covered here. Later you will have
to implement correct steering in your FDM (driving the
"/sim/model/pushback/yaw-deg") and pushback availability
("/sim/model/pushback/available") -- because those are too
aircraft-specific.
1. Set up the pushback logic. Add the following tags in your set.xml.
Replace the "/fdm/jsbsim/gear/unit[0]/steering/pos-deg" with the
property for the front wheel steering degrees of your aircraft.
Under <sim><model>:
<pushback>
<enabled type="int"/>
<available type="int">1</available>
<yaw-deg alias="/fdm/jsbsim/gear/unit[0]/steering/pos-deg"/>
<target-speed-km_h type="float">0.0</target-speed-km_h>
<K_p type="float">100.0</K_p>
<K_i type="float">25.0</K_i>
<F_i type="float">25000.0</F_i>
<K_d type="float">0.0</K_d>
<driver>
<tow-distance-m type="float">-60.0</tow-distance-m>
<face-heading-deg type="float">0.0</face-heading-deg>
<steer-cmd-norm alias="/controls/flight/rudder"/>
<K_V_push type="float">10.0</K_V_push>
<F_V_push type="float">10.0</F_V_push>
<S_min-m type="float">5.0</S_min-m>
<K_psi_push type="float">0.05</K_psi_push>
<K_V_turn type="float">1.4</K_V_turn>
<F_V_turn type="float">7.0</F_V_turn>
<K_psi_turn type="float">0.2</K_psi_turn>
<V_min type="float">2.5</V_min>
</driver>
</pushback>
Under <nasal>:
<autopush>
<file>Nasal/autopush.nas</file>
</autopush>
<autopush_driver>
<file>Nasal/autopush_driver.nas</file>
</autopush_driver>
2. Connect the FDM's external force.
a) JSBSim:
a.1. Add the following under <external_reactions> of your
JSBSim XML. Change the coordinates under <location> to equal
those of your front bogey.
<force name="tractor" frame="BODY">
<location unit="M">
<x>0.0</x>
<y>0.0</y>
<z>0.0</z>
</location>
<direction>
<x>1.0</x>
<y>0.0</y>
<z>0.0</z>
</direction>
</force>
a.2. Add the following under <fdm><jsbsim><external_reactions> of
your set.xml.
<tractor>
<magnitude alias="/sim/model/pushback/force-lbf"/>
<x alias="/sim/model/pushback/force-x"/>
<y alias="/sim/model/pushback/force-y"/>
</tractor>
b) YASim: TODO
3. Copy the gui/dialogs/autopush.xml from the distribution to your
aircraft's gui/dialogs directory. Add it to the menu (see
FlightGear documentation for editing the menu).
4. Copy the Models/Goldhofert-autopush.xml to your aircraft's Models/
directory. Edit all the places marked by "SETTING" to match your
setup. Include it in your Model XML, with offsets equal to the
front wheel's contact point.
5. Add the following in your Model XML. Change the coordinates under
<offsets> to equal those of your front bogey.
<model>
<name>Pushback</name>
<path>Models/Airport/Pushback/Goldhofert-autopush.xml</path>
<offsets>
<x-m>0.0</x-m>
<y-m>0.0</y-m>
<z-m>0.0</z-m>
</offsets>
</model>
