+Nasal is a scripting language available in FlightGear which opens up a world of possibilities for aircraft modellers - much more detailed information can be found elsewhere [[Nasal_scripting_language]].  Here, though, as a simple example to get you started, we will create a very basic script to convert engine temperatures from degF to degC, as required by the Fokker50 instruments.
+Such a script should ideally be very generic so that it can be reused easily; but the script here is deliberately kept as simple as possible.

 This listens for the fdm-initialized property to be set (this will happen when the sim has started up), and starts our convertTemp function when that happens.
+As an "exercise for the reader" (I always hate those!) you should make the script also convert the temperature values for the second engine.
+Now you should be able to take advantage of the more detailed information available about nasal here on the wiki, at www.plausible.org/nasal , and also other pre-existing nasal scripts which can be useful to borrow from!
