After have done three flights yesterday, in none of the flights I could perform an ILS Approach.
Following the step in the Airbus-A220-Pilot-Guide, as you can see in the image below, when I check the Arrival data, the ILS frequency can not be displayed.
Even if I place the ILS Freq in the Control Tuning Panel (CTP), the aircraft does not recognize it.
Is It an issue / bug ?

Hey, I haven't seen that yet. This is not a solution for your issue, but I wanted to ask, have you been able to fly an RNAV approach? Because Im having the opposite issue as you, I load the RNAV on the FMS and the airplane ends tuning and flying an ILS.

Let me know

Hi,

Can you please upload a video either to YT Unlisted or to Google Drive so that I can better try to assist. Additionally feel free to make a post on the Synaptic Discord, thank you.

I don´t know why, but know the frenquencies are being displayed. Now I need to figure out Why sometimes the aircraft is not able to recognize the frenquecies nor intercept LOC and GS.

same problem

Same problem, it's quite frustrating

Same here... from time to time on the same airport it does not set the freq for your selected rwy. Other times it work just fine.

Are you on native navdata? Synaptic have had some issues parsing the coding on them which seems to be causing both the ILS auto-tuning issues as well as the RNAV-tuning-ILS issue. If you have the option of using Navigraph can you confirm if you are still having these issues?

I also tried many times but unable to capture the localiser and GS. I have also done what you did.

EPWA rwy 33 ILS Y have same problem. No GS captured.

Fresh Navigraph data.
