Avidyne vs Foreflight waypoint navdata

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   The Jepp subscription on my ForeFlight is a device on the same subscription as the IFD navdata.... that is, Jepp data on ForeFlight, IFD100, IFD540 is all under the same subscription/coverage. This coverage is Europe IFR/VFR which includes all the VFR waypoints for Europe. However, it seems that only the charts from the Avidyne subscription map over to ForeFlight. The VFR waypoint navdata is part of the ForeFlight Europe subscription, and is coded differently from the VFR waypoints in the Avidyne.
I am seeing two issues in this regard.

Issue 1:

The IFD navdata uses VPnnn as the waypoint names for VFR waypoints. ForeFlight uses something different. This causes issues when transferring FPL/Routes between ForeFlight and an IFD and vice versa.

Example:
If I create an FPL in Foreflight on the Map page, starting in Locarno, Switzerland (LSZL) and then try to route via a couple VFR waypoints, there are two issues when transferring to the IFD.
1) Some VFR waypoints are missing in the IFD navdata. Examples for Locarno LSZL are GORDEVIO and ARBEDO. Both are missing from the Avidyne IFD navdata even though I have the VFR coverage. Both are <10nm from the airport. Although I have VFR waypoints and Intersections turned on under Setup/Map in the IFD, these waypoints are not shown on the map and don't appear under NRST Waypoints. When I transfer the FPL from ForeFlight to the IFD, the IFD creates new FFnnn user waypoints which just clutters up my user waypoints. When creating a route on the IFD it is also necessary to create a user waypoint.
2) For VFR waypoints that exist in both ForeFlight and IFD navdata, they have different name coding. In the Avidyne navdata these have the format VPnnn. That is also shown on the map when turned on. The VFR waypoints in ForeFlight have a different format. For example, Locarno LSZL VFR waypoint E is coded VP010 in the Avidyne navdata and ZLE in the ForeFlight navdata. Similar to case above, when transferring a FPL to the IFD, it doesn't recognize this and creates a user waypoint, even though it has a valid corresponding waypoint VP010. Same in the reverse direction.

Question for Avidyne: Is there any plan to coordinate on the VFR waypoint naming with ForeFlight to solve this issue?

Issue 2:

ForeFlight has some intersections starting with LSnnn for which the Navaid Type is "Named Intersection/RNAV" or simply "Named Intersection". These are not flagged as VFR waypoints nor do they show on ICAO VFR or IFR charts and they don't seem to be official IFR waypoints either. From what I can tell, they appear to have been created along mountain routes which makes routing much easier through mountain valleys and over passes. These do not show on the IFD Map, even if all Intersections and VFR Waypoints are turned on, but they are in the IFD navdata because it recognizes them. They can be entered as intersection names and will be found. They are also properly recognized if included in an FPL/Route received from ForeFlight. They just don't appear on the Map so can't be identified that way for input when adding one "on-the-fly".

Question for Avidyne: Is there any plan to add these LSnnn intersections to the IFD Map, since they are already in the navdata?
