RNAV, but no approaches. Suffix?

So what is the correct equipment suffix for an airplane that can navigate direct, can take RNAV arrivals and departures, but due to company policy cannot do an RNAV approach. Assuming Mode C transponder, I think it is /I. What do you think?
 
RNAV stuff is now domestic ICAO data.....

So before the switch a Boeing 767-200 without GPS in the FMC (and no RNAV approach OpSpec) would be filed as either H/B762/J or H/B762/Q. Now that same aircraft is: B762/H-SDIRWZ/C and NAV/RNVD1E2A1 (indicating RNAV SID/STAR and Q/T Airway approval).

/I is basic RNAV without RVSM.

Hope this helps.

I only know the NAV/ codes that pertain to my operation, but even my slightly inebriated self knows that the A1 portion means RNP10 qualified. Not sure if RNAV equipment implies RNP10 but I am pretty sure it does not. I would need my cheat sheet to know what D1 and E2 mean.

I don't know the full requirements for ICAO 2012 for domestic only flights, but our flight progress strips still contain the legacy /codes (/a /u /q etc etc). We aren't the RNAV police. If you tell us you are unable to fly an approach we'll issue a different one.

Just out of curiosity, could you fly an ILS approach that requires RNAV capabilities? We have a few of those.

You're close..... those things you are talking about is the new PBN/ part of the ICAO 2012 changes. So if the airplane had RNP10 certification as well as RNAV SID/STAR/Enroute it would be: PBN/A1C4D4. One of the theories behind the new PBN/ item is exactly for this scenario because the PBN/ codes include RNAV(GPS) and RNAV(RNP) approach identifiers as well the regular RNAV en route stuff.

The D1 and E2 and, for that matter, A1 that I talked about above are part of the NAV/ input.

So it would be: B762/H-SDIRWZ/C NAV/RNVD1E2A1 PBN/A1C4D4

Confusing aint it ;)

Depends...... always read the chart notes. If you're talking about ICAO PAN-OPS constructed procedures, they always include the updating requirements in the procedure notes (e.g. GNSS only or GNSS - DME/DME - VOR/DME).
 
It is very confusing. I put in he aircraft info and fltplan.com spit out -SDGRZ/P PBN/B2C2D2 NAV/RNVD1E2A1.

Yeah I realized that after I went to work today...like I said, I was slightly inebriated. The second part was more directed toward the OP, since his company does not allow RNAV approaches.

Edit: And yeah, it is confusing. I just about had the old ICAO system down and then they switched to the new format.
 
/G. If they try to give you a GPS approach just tell them "unable."

No need to get overcomplicated.

That is what is commonly done, but I was looking for the correct way. /G explicitly includes approaches.
 
Controllers rarely even notice what your equipment code is to begin with. I seriously wouldn't stress over something so small.

You have no idea how many times I have been cleared direct to something 200nm+ away even though my equipment code is /A. They seriously don't look or care. They just assume you have a GPS on board.

That said, the equipment code isn't wrong by saying /G as the plane is capable of GPS approaches. If it comes down to it company policy goes out the window when the crap hits the fan.

Similarly, I have air taxis file /U then ask for VFR GPS direct daily. It's all a wash in the radar environment anyway.
