And you need approval for certain PBN codes such as A1 and L1. In the US, you need to obtain a LOA from the FAA local FSDO
Is that LOA linked to aircraft equipement? or also include the operator pilots?
T1 for RNP AR APCH goes as approval for operator + aircraft
Here is a thread from the earliest days of EuroGA.
It is a good Q as to whether anybody cares about equipment codes. Those who actually know will almost never talk about it openly, because it touches ATC policies which are not openly published. But in general you can declare all kinds of stuff which you do not have, and nobody will notice. There have been suggestions that you may not be offered an RNAV procedure if your FP codes do not include B2 or D2 or whatever, but I am not sure any of that is true.

Do you need to include “NAV/SBAS”? I’ve never done it and I don’t see what that information would be used for.
From Garmin: NAV/SBAS is entered to indicate WAAS capability and the ability to fly LPV approaches.

Selecting “B” from the equipment list in Field 10 also indicates LPV capability, so there does seem to be harmless duplication.

I believe both pilots and aircraft.

Yes, B is what I use.
I just checked the IPFS User’s Manual and it did say you “should” use NAV to indicate GNSS augmentation like “NAV/SBAS”.

I have never been cleared for an LPV approach nor does ATC care if I have SBAS or not. I have flown hundreds of RNAV (GPS) approaches that have an LPV line of minima, but ATC doesn’t know I have chosen that line of minima nor if my aircraft is capable.
You will be cleared to fly RNP anyway the minima will depend on your annunciation? if it’s an RNP approach with “LOI annunciation” your minima is MSA
But ATC care to know if you are PBN/RNP or Conventional…
A while ago I spent a while trying to figure this out for a non -w 430. I decided to just use B2C2D2O2S1. I leave out the oceanic stuff because I know it needs approval, the rest I add what Garmin says the box is capable of. It is made much too difficult in my opinion to find the letter of the law on this and as mentioned already, it doesn’t really matter anyway. I have tried my best to be correct and if I have it wrong then so be it.

Of course not. You’re cleared for an RNP approach. What minimum line you use is not something ATC cares about.
In Europe, ATC (or rather flow control) does care about your minimum RVR, but I don’t think that’s relevant for CAT I operations.

You might have been cleared for an RNP approach that requires GNSS, but I have never been cleared for an RNP approach, only an RNAV approach and they require GPS.
