Hello,
Will the flight plan generator be updated with the new flight plan symantic, active as of November 15th?

Note that copying FP data generated by Skydemon 2.4.3 into the test application found at EuroControl still gives errors.

SkyDemon 2.4.6, released today, contains the new NAV/COM equipment codes to be compatible with the FPL 2012 changes. Other aspects of our flightplan generation engine were already compliant.

There is no benefit to specifing "S" for standard equipment in SkyDemon, you just pick what you have and don't have to worry about what is included in "standard" equipment. SkyDemon will convert your selections to an "S" where appropriate.
