Welcome to low wing loading. That's a fact of our life. What you can do:

  1. Wear Clarity Aloft or similar headsets so there's more headroom. Make sure your ball-cap doesn't have a button on top.
  2. Put insulation on any bars your head can hit. Don't use the neoprene, look for the more rigid foam stuff. It lasts a long time and stays nice looking.
  3. When flying try to let the plane do what it wants as much as possible. That's to say, you don't want to add your own turbulence caused by control inputs. After a while, you get good at responding to turbulence as it happens. I used to roll in aileron as the wing lifted, sorta just keeping the stick vertical and letting the plane roll into it. As the gust passed and the aileron took hold and rolled the plane out I just kept it vertical until the plane was horizontal and there was no more aileron input.
  4. I finally learned that it was best just to ignore changes in altitude, assuming you were high enough, because doing so always put me out of phase with what the air was doing so I was constantly climbing and descending. In the old days, with the 582, that was a major pain. Now I just let the plane go up and down, sometimes +/- 500', but try to average my altitude. If you're talking to ATC, tell them your problem and ask for a block altitude.
