<PropertyList> <name>Taxiing</name> <description> This tutorial covers moving the aircraft around on the ground, from the parking position to the run-up area. For more information on taxiing, see Section 2-9 of the FAA Airplane Flying Handbook available at http://www.faa.gov/library/manuals/aircraft/airplane_handbook/. </description> <audio-dir>Aircraft/c172p/tutorial/startup</audio-dir> <timeofday>morning</timeofday> <presets> <airport-id>KLVK</airport-id> <on-ground>1</on-ground> <runway>12</runway> <altitude-ft>-9999</altitude-ft> <latitude-deg>37.6952</latitude-deg> <longitude-deg>-121.8167</longitude-deg> <heading-deg>175.0</heading-deg> <airspeed-kt>0</airspeed-kt> <glideslope-deg>0</glideslope-deg> <offset-azimuth-deg>0</offset-azimuth-deg> <offset-distance-nm>0</offset-distance-nm> </presets> <targets> <j1> <!-- Turn right onto taxiway --> <longitude-deg>-121.81664</longitude-deg> <latitude-deg>37.6949</latitude-deg> </j1> <j2> <!-- Mention differential braking --> <longitude-deg>-121.82258</longitude-deg> <latitude-deg>37.6949</latitude-deg> </j2> <j3> <!-- Left turn in taxiway --> <longitude-deg>-121.8250</longitude-deg> <latitude-deg>37.69498</latitude-deg> </j3> <a1> <!-- Right turn onto taxiway A --> <longitude-deg>-121.8251</longitude-deg> <latitude-deg>37.694616</latitude-deg> </a1> <a2> <!-- Runup aread --> <longitude-deg>-121.8294</longitude-deg> <latitude-deg>37.69459</latitude-deg> </a2> </targets> <init> <set> <property>/controls/gear/brake-parking</property> <value>1</value> </set> <set> <property>/controls/flight/flaps</property> <value>0.0</value> </set> <set> <property>/controls/engines/engine/magnetos</property> <value>3</value> </set> <set> <property>/controls/engines/engine/throttle</property> <value>0.07</value> </set> <set> <property>/controls/engines/engine/starter</property> <value>true</value> </set> <set> <property>/engines/engine/running</property> <value>true</value> </set> <set> <property>/instrumentation/adf/frequencies/selected-khz</property> <value>340</value> </set> <set> <property>/environment/weather-scenario</property> <value>Fair weather</value> </set> <set> <property>/controls/flight/elevator-trim</property> <value>0.17</value> </set> </init> <step> <message>In this lesson we'll taxi the aircraft from its parking position infront of the FBO, along taxiways Juliet and Alpha to the run-up area near runway 07L.</message> </step> <step> <set> <property>/controls/engines/engine/starter</property> <value>false</value> </set> <message>I've already started the engine.
