I have the APX 340 transponder which is 1090 out and the MLB 100 which is 978 in. I'm still confused as to which ICAO surveillance codes to use in flight plan filing. I assume I would select B1 because that is ADS-B 1090 out but I don't see a selection for 978 ADS-B in. Would "E" be my selection as it is for Mode S, ID, Alt, and Squitter? What codes have others with this setup used?

Same setup, B1 and L transponder.

Hope to be B2 soon when the Freeflight RANGR dual frequency becomes available.

if you have the same setup, why did you select L? I chose B1 and E. The L includes some enhanced surveillance that E doesn’t have. I’d like to get dual band also.

That's a good question, might have done it in error when I first set up the codes in fltplan.

Is the AXP340 Euro compliant with the DAPS code?

I have this same question. I am setting up my airplane in Foreflight, and not sure which ICAO codes to use.

AXP340 and a Skytrax100 here as well.

This is what I use with my IFD440 and Lynx NGT9000:

Item 10: SBGRY/EB2

(some say Y is not necessary in the US because ATC does not use those frequencies in the US)

Item 18:

PBN/B2C2D2S1 SUR/260B CODE XXXXX (where XXXX is your aircraft's assigned code)

The Z code in Item 10 is to flag the use of NAV/ in Item 18. Since there's no need for a NAV/ entry in Item 18, there's no need for a Z flag in Item 10. The PBN codes are to show the RNAV 5, 2 and 1 capability, and the RNP (but not RNP AR) approach capability, that the IFD is certified for. The SUR/260B in Item 18 is a required entry to show ADS-B 1090 compliance. It's a different required code if you complied with the FAA's ADS-B rule with a UAT transponder.
