In nuc_p function in pyModeS/decoder/adsb.py:

    if tc in [20, 21]:
        RCv = uncertainty.NA

But in the ICAO document, it says that vertical position error should be 4 and 15 for typecode 20 and 21, it seems?

@wrobell, would you please point out where these are mentioned in the official document? I wasn't able to find it. Thanks.

Appendix A, page A-7, table: “TYPE” Subfield Code Definitions (DF = 17 or 18)
