+==== ATC-Transponder ====
+The transponder sends signals to air traffic control to identify the aircraft on the radar screens. A unique four digit code is given to each aircraft that is in the airspace of the controller. This is called the Squawk code or just transponder code.
+To enter a code you can either set up control clickspots with the message ''Communication.TransponderDigit'' to enter one digit after the other (like in the default Cessna 172), or ''Communication.TransponderCode'' to directly change one of the digits (like in the default Baron 58)

 First of all a radio frequency input is required, this is handled by the ''input_pair'' that can tune a standby frequency and then swap to the active frequency. We send these frequencies to outside devices using [[aircraft:tmd:sender|sender]] objects to be displayed on external panels for example.
-Secondly a course selection has to be made, this happens with an ''input_cyclic'' from 0.0 to 6.28 for the course (see heading indicator).
+Secondly a course selection has to be made, this happens with an ''input_cyclic'' from 0.0 to 6.28 for the course (see heading indicator). You may know this as the OBS knob.
 Lastly we can give the receiver these values and it will spit out a multitude of outputs.
