Hi, I am flying the Alabeo C-177 using the stock GNS430 with Navigraph charts.
When I fly the RNAV 21 into KFFA the GPS guidance from YELUS (IAF/IF) wants to send me to UHAWO (FAF) on a 176 TRK instead of a 148 TRK as per the chart. It looks like the 148 degree segment (1600/9.3nm) to the FAF is just missing from the approach.
This happens when I start the approach from OCSIP.
Here is the Aerograph/NACO chart:
Any idea on why?
Looking at the “Custom Data/GNS430/navdata/Proc/KFFA.txt” I see:

I believe the problem is the OCSIP APPTR (approach transition?) is missing a third line to turn to a 148 degree TRK like the other two transitions.
