TEC/Preferred routes

[anonymous555]

Offer a way in little nav map to provide preferred routes and/or TECs , perhaps through the route generation wizard. Right now it's a bit painful/convoluted to find appropriate routes from here and import them into little nav map.

The official database is available as a free .csv file here

(Found via this website):

It would be great to offer a way to import this and use it.

Thank you for the links.
I'm not sure if I can integrate this into the LNM automatic route calculation. Looks like a huge effort to me but it could make sense for the manual planning mode ( #357).
