ICAO Flight Plan

Have you (Adventure Pilot) given any thought to needed software changes for filing ICAO plans from iFly?

I see you already have incorporated a couple of the new fields. I'm wondering now about the non-ICAO airport identifiers.

For example, filing from L35 to O22 on the FSS website ICAO form has to be entered as ZZZZ for both the departure and destination fields, with /DEP L35 /DEST O22 entered into the "other information" field.

Roger, I'm forwarding this to development for clarification.

Re: ICAO Flight Plan

Thank you for bringing this up. This topic was last discussed with LMFS almost 2 years ago, when they forced all vendors to changeover to ICAO format, which means that all non-ICAO airport codes become "exceptions", and must be entered into "other information" as you have noted. This is their requirement, and is supposedly "OK".

I have re-raised this issue with LMFS today, and will notify you of their response, as to whether or not this issue is going to be addressed, or if they are just going to leave it "as is".

Re: ICAO Flight Plan

Here is the response from LMFS regarding this inquiry:
====
The “ZZZZ” is part of the ICAO 4444 standard and is what pilots should be expecting when filing an ICAO FP.

I believe the latest standard is available from ICAO for purchase but there are older copies on their website and elsewhere on the internet. This has been around for at least the past 5 years or longer in the standard so I do not anticipate it changing anytime in the near future.
