This is a 3D plot of my track as I climb up in front of the wave cloud in the secondary wave. On this day, a tow to only 2000 ft AGL was required to get into wave, and because the airport was upwind of the secondary, we did not have to fly through any rotor!
Shown here is the excursion that I took out toward the Champlain Valley - as seen in the last photograph on the picture page
At the end of my flight, I was back in the secondary wave and flying south. The lift was 1 knot up or so and I flew a long distance south this way. It makes for very comfortable cross country flying. The only disadvantage was that the winds were more NW this day and it too a bit of time to fly back against the wind.
