The not so surprising part (given that it does have this capability) is that you can induce the slew when there is no wind by rolling the stick in the cal process
The 64 dollar question is their a key that will re-center the sight though ?
In other words if you have inadvertently introduced a slew when none is required (and you find your sight view crabbing), what if any key will set things back to ZERO ZERO (start from a fresh tablet) ??
Also if you could Rolex, please explain in a little more detail the mechanics of what is happening here. I would assume that step one in calibrating for wind is to make absolutely sure your plane is crabbed into the wind and on the right track such that its velocity vector will carry it directly over the target. Further I would assume that step two is to then induce a slewed calibration procedure by in essence looking both forward and to one side or the other.
In other words do you have a written procedure for crosswind manual calibration?
Any further information on this rather fascinating puzzle is right up my ally...I am into mathematics as they apply to flight and how the game represents it
