A special Bespoke Event called "Start" (case is ignored) can be created for each aircraft which will automatically run during the Synchronizing Selectors and Switches phase (note that it may take 25 secs to start if no data is being transmitted by the aircraft). Simply Add a new Bespoke Event and name it Start.
The "Start" event will automatically run in the background on its own thread. If its built as an infinite loop (e.g. uses Goto to continually loop back to the start) it will never end and run continuously as the 60000ms timeout for background based Bespoke Events is ignored for "Start".
Please be careful if you create an infinite loop by adding a suitable "Sleep" time within the loop otherwise system CPU usage will surge to 100% and the system will slow down.
