I'm pretty new to PMDG. The only plane I've flown so far is the 777-200LRX. I've familiarized myself with most systems in the 777, but recently I've had trouble loading RNAV Departures/Arrivals into the FMC. When I select DEP in the DEP/ARR menu, there just aren't any RNAV's available. Is there any way to see the RNAV or do they just not have them?
