I have flown many approaches now with the Kodiak (ILS and RNAV (with GPS glide slope if available)) and I’ve not had any problems. I do use the G1000 Nxi though. I know that Simworks mentioned that they focus on the G1000 but they also say on their website that the aircraft supported the Nxi at time of release, and that as the Nxi gets updated, they’ll update the aircraft. The old G1000 is EOL, and terribly frustrating to use because of all the bugs.
Anyway I certainly hope that Simworks will continue to keep the aircraft Nxi compatible as the Nxi evolves because it is hands down my favourite aircraft. However, if it means going back to the old G1000 in the future that will be the end of the Kodiak for me.
