FLT-DATA NA vs NAN

[toby23]

I have searched high and low, probably in all the wrong places, to find out what FLT-DATA NA and NAN stand for.
It would appear no-one has asked this question before, which confounds me.
I don't want to guess, so am leaving this here for your eagle eyes Nick.

Thank you

@toby23 Would you believe that it's "North America", and "North America Not "? Makes no difference which one you select in the simulator, for reference.

I had a feeling it was North America but I never would have guesses it's Not! Thank you - I'll let you get back to the Twin Commanders... which in case no-one has mentioned, are looking incredible!
