I know what RNAV means. "Area Navigation" using VOR/NDB/GPS/ILS etc.
I also know the difference between VFR and IFR. But...
What does the term "Non-RNAV" mean?
Eg. Creating a flight plan using FltPlan.com.
Three options:
1. IFR (ICAO format) required for all non-USA and all RNAV flight plans.
2. IFR (Domestic format) For USA, non-RNAV flight plans.
3. VFR
Thx in advance.
NDBs, ILS and normal VOR operations are not RNAV. RNAV means your aircraft has the equipment on board to navigate to arbitrary lat/lon fixes. Usually this means GPS. T and Q routes are RNAV routes, V and J routes are not. Sids and stars may be RNAV or non-RNAV, and are labeled RNAV as appropriate.
FYI, the non-ICAO IFR flight plan is going to be completely phased out soon. The decommissioning of hundreds of VORs, plus the addition of thousands of GPS approaches, is pushing this change. ATC needs more detail about your aircraft's capabilities before giving you your clearance. The ICAO format allows you to specifiy with greater detail what kind of equipment you have on your aircraft. Plus, we really want to know what color your dinghies are.
