NAT Tracks example with RLAT – 2017

With the new (ish) RLAT Tracks, the standard NAT Track picture looks different these days. We thought we’d draw one out so you can see the RLAT Tracks. This example is the Westbound Tracks today, February 24th 2017. The RLAT Tracks are C, D, and E.

The neat plotting chart that this is drawn on is from Flight Service Bureau and available here.

Picture first (click for big version), Track message follows:
