Good Morning to everyone stateside, Good Afternoon, Good Evening, and Good Night to everyone else in other time zones!
Hopefully I'm posting this in the right place. I've been using FR24 for quite some time now, but just became a Gold member recently. I'm trying to learn about how to read the radar screen using the ODA High / ODA Low / and RNAV routes. I've read the blog post about the route names and distance between waypoints. I've got a question about what I think are called "NAVAIDS".
I mostly watch ORD airspace, and have spotted what look like snowflakes with two letter designations. If I zoom in, I see the full name of the map marker. These names are Jocky, INDDY, and Chicago OHA TAFFS. What am I seeing? Where can I read about what their functions are and how / when they're used? Thanks for your patience ahead of time!
