Com Frequency ID data source?

   Is Jeppesen navdata the source for the IFD identification of frequencies?
I'm finding that information frequencies here in Europe are not identified, either in the frequency box (shows only as COM) or in the frequency list presented via the FREQ button (flagged as unknown if in the recent list). And the frequencies don't appear at all in the FREQ ENROUTE tab, which they should for the current GPS location area.

I flew from Switzerland to Italy and back last weekend and the following frequencies were not identified:
- 124.700 (Zurich Info)
- 124.150 (Padova Info)

These are in the Jepp information presented in ForeFlight, so it's not clear why they don't appear on the IFDs.

	The database does contain those two enroute frequencies, but the system only looks for ARTCC and FSS. We can consider expanding the lookup to take other kinds of frequencies into account.

	Steve, In fact, FIS (Flight Information Service) frequencies like these are sort of the European equivalent of the American FSS so they really should be treated the same. All or almost all European countries have these frequencies to provide primarily VFR flights with weather and traffic information services, flight following, and in some countries even relaying airspace clearances on behalf of ATC or the Military. There are 2 for Switzerland: Zurich Information 124.700 and Geneva Information 126.350. Directly from the Swiss ICAO 1'500'000 cover page: Edited by chflyer - 20 Sep 2019 at 3:36pm
