![]() ![]() Check the property-tree at /sim/systems/autopilot Not only will you have no weather anymore, but also 2 systems that will most likely overwrite each others results all the time. Then you override these generic configs with your own, which may lead to strange behaviour, if you for example overwrite the weather rules with an autopilot-helper configuration. Anyway, it shouldn't hurt to do so.įG first loads generic configs, which get indexed atomatically as they appear. Note While the above seems to be the recommended standard, it has occasionally lead to trouble, not to index additional autopilot configurations. For example, lateral and vertical autopilot modes could live in separate files, as could a yaw-damper system. They run in the order of appearance under. Note, that more than one node may be present, each will create a new instance of the autopilot subsystem when running FlightGear. The only disadvantage is that they will be split between an autopilot and a property-rule configuration file.įor example would a fly-by-wire flight control system element augmenting an unstable aircraft need to run at FDM rate, while an element depending on the flap extension would work just as well at frame rate.Ī configuration is added to an aircraft by adding the path to an XML configuration file to the -set.xml file.Īutopilot configuration files are added to the aircraft by addingĪircraft/MyAircraft/Systems/my-autopilot.xml They can communicate with each other using properties. ![]() It is possible to implement a system using both autopilot and property-rule based elements. Depending on FlightGear settings and the hardware, the FDM rate is about 2–10 times higher than the frame rate. Using property-rule elements for things that does not have to run a FDM rate can improve the frame rate, in particular for complex systems and on weaker computers. Property-rule configurations run at frame rate.Autopilot configurations run at FDM rate.The main difference between XML based autopilot and property-rule systems is the update rate: 8.12 Coherent-noise filter (random number generator)Īutopilot vs.5.9.4 Periodical transformation of the input value.5.9.3 Linear transformation of the input value.5.6 Input and reference properties or values and.5.4 Initial value (only available for elements).2.2 Adding a property-rule configuration.2 Adding a configuration to an aircraft. ![]()
