Itís simple. To go from A to B, you just draw a line and add a fix or two. But, what about fuel stops, special use airspace, minimizing distance? Maybe thereís more to thisÖ
This is a long flight, so you want to minimize distance and go as direct as possible. You scan the route from TAFOY to KFSM on the chart, and it doesnít pass through any special use airspace (SUA), so you could go direct. But, you want to comply with the AIM guidance (see below) and pick a fix or two in each centerís airspace. You zoom in on the chart to see TAFOY clearly, then just scroll the chart to the east along your route, looking for fixes on your route that you could add.
