Deleting multiple user waypoints

My routine with my GNS 430W was to plan all of my flights at home on ForeFlight, and then upload them into the panel when I get to the plane. This also works well for an out and back flight; while the navigator forgets the route after shutdown, ForeFlight remembers, and a simple upload gets the plan back onboard. No need to use a saved route.

One byproduct of this usage model is that each waypoint that does not correspond to a charted waypoint is stored as a user waypoint in the navigator. On the GNS over time these waypoints clog the display up, and since I have no reason to keep them, every once in a while I’ll go into the user waypoints list and select the menu item “Delete all User Waypoints”. Problem solved.

Now, with the IFD, not only will I create new user waypoints, I may also start collecting rubber band waypoints when I modify routes, which appear also to be stored in the IFD user waypoint space. Happily, they don’t show on the map unless you reference them in a route, but they do still collect in the WPT display. 

How can I mass delete all of these waypoints? I’m thinking that creating a blank excel spreadsheet and importing it might do the trick, but if there is an easier way, short of individually CLRing each one, I’d like to know what it is.

Thanks!

This is incorrect (10.3.1.2). I uploaded a CSV file with user waypoints yesterday and the waypoints were merged in with the existing user waypoints on the IFD. It would be nice if it would work as described in the Pilot Guide. It would be a relatively easy way to accomplish what Melohn is requesting..... export the user waypoints to a CSV file, update the file removing the undesired waypoints, then upload the new CSV file without the deleted waypoints. 

If I want to replace the user waypoints with a new CSV file contents, are you suggesting that I need to power off both IFDs and load the new CSV into both before bringing them online together?

I asked about the IFD100 just in case it would have tried to sync its waypoints to the IFD as well.  Best to just clear them all from everywhere before uploading the CSV into one.

There doesn’t appear to be a way to delete all waypoints on the IFD trainer or IFD100. However, it’s a lot easier, albeit annoying, to press the CLR button on your iPad at home versus sitting in the cockpit with the power on trying to do the same thing.

I don’t think I understand the logic about syncing between the IFD 100 app and the IFD devices; some times, the app seems to be busy syncing routes and presumably waypoints, while other times it doesn’t seem to even try. Some manual control or method to monitor what it’s doing and how far along might be helpful.

I’ve turned off the ForeFlight feature to sync user waypoints, as recommended by Avidyne, and it has made the flight plan transfer much more reliable. However, some form of transfer, perhaps in the background, might be helpful someday, particularly since it is easy to delete all waypoints from ForeFlight. 

I have found that if you use the same waypoints from a stored route on ForeFlight, they will not create new waypoints on the IFD. However, for those of us who fly complex search patterns that are one time only, the number of junk waypoints does pile up, and it would be helpful to have a way to just clear them out.
