Thanks!
Hopefully you've got it from the previous posts that the wind side of the E6B is for flight planning using forecast winds to determine drift angle.
In flight, fly a known distance and time how long it takes to cover that distance. In the cockpit, you'll have to be able to fly a steady course, recognize two points on the ground, and measure the distance between the two points on a sectional.

Timing one minute makes for easy base-6 math but remember that the longer you time the more accurate your calculation.
