Maximum number of waypoints?

Charts General
1

I’m trying to “reverse engineer” a flight plan in Charts. I exported a Flightaware KML file and was able to convert it to a format that I could import into Charts. It ended up being 1200+ lat/long waypoints. When I try and view it in Charts, the flight plan won’t load. It gets stuck on the panel with Origin and Destination. I see that the call to https://fmsdata.api.navigraph.com/3/routing returns a 414 URI Too Long error. What is the limit for the number of waypoints? I realize this is a non-standard use case. Thanks.

Hi Jonathon,

It looks like a maximum of 200 waypoints.

Thanks Ian. I know nothing of the downstream implications, but a POST request instead of GET to the routing API could accept a larger payload of waypoints. Cheers.

Hi Jonathon,

We have investigated the maximum number of waypoints. It turns out there are multiple technical reasons for the existing maximum including the API and distributing the large number through our worldwide Charts distribution network.

Cheers
Ian
