Hi everyone,

it would be a great feature to also see the FMCs in the little Frequency window in the top left for the applicable sectors of FIS. Or maybe also in the Airspace details when double tapping on an airspace. (See my example screenshots attached)

In Germany we have this now on several FIS Frequencies and I think in the UK it’s also a thing.

Best regards

Emil

Hello Emil,

welcome to the forum and thank you very much for your suggestion for improvement 👏

I think that can be implemented, and I’ve added your suggestion to the to-do list 😀👍

Hi everyone,

I’d also love to have that in VFRnav and I already use the FMC regularly — it’s worked very well so far. However, it’s currently limited to 4 FIS sectors and is only available until 29.10.2026, so maybe we should wait to see how things develop before Hermann puts programming effort into it.

Regards

Stefan
