I am using the GNS530 with the PMS50 mod … when I select an ILS approach and transition, and subsequently activate it, it seems to go ‘direct to’ the FAF not the IAF. I have to manually add ‘direct to’ the IAF to be able to fly the ILS …
For example I just flew to KDET ILS 33, and selected transition OBZOF (which is the IAF). GPS took me straight to GOMAC whcih is the FAF.
This behaviour seems wrong, or at least different to G1000nxi.
