<?xml version="1.0"?> <PropertyList> <name>Before Takeoff Checks</name> <description> This tutorial covers the before takeoff checklist. This involves the engine checks that are made in the run-up area just prior to taxiing to the runway and taking off. For more information on the before takeoff checklist, see Section 2-11 of the FAA Airplane Flying Handbook available at http://www.faa.gov/library/manuals/aircraft/airplane_handbook/. </description> <audio-dir>Tutorials/startup</audio-dir> <timeofday>morning</timeofday> <presets> <airport-id>LELL</airport-id> <on-ground>1</on-ground> <runway>20</runway> <altitude-ft>-9999</altitude-ft> <latitude-deg>41.52328208</latitude-deg> <longitude-deg>2.100250035</longitude-deg> <heading-deg>55.0</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> <step> <set> <property>/sim/model/c172p/brake-parking</property> <value>1</value> </set> <set> <property>/controls/switches/master-bat</property> <value>true</value> </set> <set> <property>/controls/switches/master-alt</property> <value>true</value> </set> <set> <property>/controls/switches/master-avionics</property> <value>true</value> </set> <set> <property>/controls/flight/flaps</property> <value>0.0</value> </set> <set> <property>/instrumentation/adf/frequencies/selected-khz</property> <value>367</value> </set> <set> <property>/environment/weather-scenario</property> <value>none</value> </set> <set> <property>/controls/flight/elevator-trim</property> <value>0.17</value> </set> <set> <property>/controls/switches/magnetos</property> <value>3</value> </set> <set> <property>/controls/engines/current-engine/throttle</property> <value>0.2</value> </set> <set> <property>/controls/engines/engine/primer</property> <value>4</value> </set> <set> <property>/sim/model/c172p/securing/chock</property> <value>false</value> </set> <set> <property>/sim/model/c172p/securing/tiedownL-visible</property> <value>false</value> </set> <set> <property>/sim/model/c172p/securing/tiedownR-visible</property> <value>false</value> </set> <set> <property>/sim/model/c172p/securing/tiedownT-visible</property> <value>false</value> </set> <set> <property>/sim/model/c172p/securing/pitot-cover-visible</property> <value>false</value> </set> <set> <property>/sim/model/c172p/cockpit/control-lock-placed</property> <value>false</value> </set> <set> <property>/sim/model/c172p/cockpit/control-lock-visible</property> <value>false</value> </set> <nasal> <script> setprop("/controls/engines/current-engine/mixture", 1.0); setprop("/controls/switches/starter", 1); </script> </nasal> <message></message> <view> <heading-offset-deg>0.0</heading-offset-deg> <pitch-offset-deg>-12</pitch-offset-deg> <roll-offset-deg>0.0</roll-offset-deg> <x-offset-m>-0.21</x-offset-m> <y-offset-m>0.19</y-offset-m> <field-of-view>73.6</field-of-view> </view> </step> <step> <message>In this lesson we'll cover the pre-takeoff checks.</message> <nasal> <script> var listeners = std.Vector.new(); listeners.append(setlistener("/engines/active-engine/running", func (node) { if (node.getBoolValue()) { setprop("/controls/switches/starter", 0); foreach (var listener; listeners.vector) { removelistener(listener); } listeners.clear(); } }, 1, 0)); </script> </nasal> </step> <step> <message>You can access the pre-takeoff checklist by selecting Help->Checklists from the menu.</message> <wait>10</wait> </step> <step> <message>The parking brakes are already applied, so our first check is that the flight controls are free and correct. </message> </step> <step> <message>Check that moving the yoke from left to right moves the aileron in the expected manner.</message> <view> <heading-offset-deg>105.2</heading-offset-deg> <pitch-offset-deg>1.0</pitch-offset-deg> <roll-offset-deg>0.0</roll-offset-deg> <x-offset-m>-0.3</x-offset-m> <y-offset-m>0.2</y-offset-m> <z-offset-m>0.4</z-offset-m> <field-of-view>55.0</field-of-view> </view> <marker> <x-m>1.4000</x-m> <y-m>-4.0000</y-m> <z-m>0.3000</z-m> <scale>41.0000</scale> </marker> </step> <step> <message>Now, check the other aileron.
