I received a letter from the FAA, they are unhappy with my Source Integrity Level.

See report: https://www.dropbox.com/s/pre3vd0ptcpfh7s/a442b69d-f3c8-4d9f-a52f-83653fd7a20a_PAPR_20191211_A94C5B_416154420%20%281%29.pdf?dl=0

I did some research and it looks like the GPS SRC on the GTX345 needs to be 17-E. The IFD440 serves as the GPS SRC. Would someone be able to confirm this setting?

Many thanks.

I'm seeing a very similar issue with a IFD 440 and GTX345. Were you able to get it figured out?


I was told by support that it was due to the baud rate, and having in/out both on RS232 channel 1.  I've messed around with config a bit but I haven't had a chance to fully verify the changes to see if that solves my issues.

Thanks for the confirmation. It looks like my remaining issue was having the GTX345 set to Integrity: Auto instead of 1e-7.
