The textual Route description says
BARPI TWO KILO
Climb on track 315 to 1700 ft; LT to PZ L; overhead PZ L; LT on HDG 295; intercept PZ QDR 325 PZ L to BARPI. Cross PZ L at 3400 ft or above.
Now the navigator in my aircraft can load and fly this procedure perfectly based on GPS along, without ever referring to the ADF which is only installed in the aircraft for compliance reasons.
But what if the PZ locator is NOTAM-ed out of service? Can ATC still assign this SID?
I'm torn on this as on one hand it is a navaid that is part of the procedure, but on the other hand this is is an RNAV SID anyway (it ends at a fix) so they know I'm still capable of navigating to "PZ L" with the exact same accuracy as before.
Approaches are another, much clearer matter, but I could not find anything official on SIDs/STARs.
This example is EASA (Slovenia) by the way, but of course we can discuss national differences if there are any.
