You might like to think about:

Z_Accel_y = cur_Plane.getParameter(part.ParameterTypes.Z_Overl oad, 1);
Z_Accel_z = cur_Plane.getParameter(part.ParameterTypes.Z_Overl oad, 2);
x = accleration fore/aft
y = accleration left/right
z = accleration up/down
z lets you know if you are accelerating up or down (changing height).

Not right? I guess that depends on your point of view, in either case, using the ROC velocity or accelerations to filter the MAX TAS is better than using neither!
The only down side to using the accelerations is they are never zero, so you will have to do some testing and thinking about what values of acceleration to use as the pass fail.. Where as the velocity is a little more intuitive, granted, the velocity alone has issues, in that a transition from the pos limit to the neg limit through zero could result in a bad MAX TAS being called good, where as using the acceleration would not be fooled by such a transition.

Its surprising how quickly it settles down, maybe 5 minutes, and how stable and predictable the returns are even over minor changes in height and Z_Accel_z ('G'). Makes it easy to see where speed is changing and why and to pick out the most appropriate result.

The eyeball method is great when you have just a few of your own tests to review.. But it starts to become a very big task once the number of tests increases or you have to start reviewing the results of other peoples tests.. Which is something I use to do for people 10+ years ago when this sort of testing was done with IL-2.. But these days I am just too busy to do that, which is why it is my goal is to provide tools that anyone can to use that automate such tedious process and to make it more standardized.
