If you wish to implement the ilec-sc7 on your glider, You will need to : * call the ilec-sc7.xml file from your model xml file * call the ilec-sc7.nas script from your [aircraft-name]-set.xml file * modify your sound.xml, including the following lines : <variometer-up> <name>variometer-up</name> <mode>looped</mode> <path>Instruments-3d/glider/vario/ilec-sc7/vario.wav</path> <condition> <and> <greater-than> <property>instrumentation/ilec-sc7/audio</property> <value>0</value> </greater-than> <greater-than> <property>instrumentation/ilec-sc7/te-reading-mps</property> <value>0.01</value> </greater-than> </and> </condition> <pitch> <property>instrumentation/ilec-sc7/te-reading-mps</property> <factor>0.246</factor> <offset>1.0</offset> </pitch> <volume> <property>instrumentation/ilec-sc7/volume</property> <max>1</max> </volume> </variometer-up> <variometer-down> <name>variometer-down</name> <mode>looped</mode> <path>Instruments-3d/glider/vario/ilec-sc7/vario2.wav</path> <condition> <and> <equals> <property>instrumentation/ilec-sc7/audio</property> <value>2</value> </equals> <greater-than> <property>instrumentation/ilec-sc7/te-reading-mps</property> <value>-10.66</value> </greater-than> <less-than> <property>instrumentation/ilec-sc7/te-reading-mps</property> <value>-0.01</value> </less-than> </and> </condition> <pitch> <property>instrumentation/ilec-sc7/te-reading-neg</property> <factor>-0.05</factor> <offset>1.0</offset> </pitch> <volume> <property>instrumentation/ilec-sc7/volume</property> <max>1</max> </volume> </variometer-down>
