there's this parameter
[Misc.: Machine Overload under Acceleration]
/// <para>Indicates overload in m/s/s.</para>
/// <para>Generic subtype (-1) shows accelerometer, being 0 under normal conditions;</para>
/// <para>Subtype 0 shows acceleraton along machine's X axis;</para>
/// <para>Subtype 1 shows acceleraton along machine's Y axis;</para>
/// <para>Subtype 2 shows acceleraton along machine's Z axis.</para>
if doing the test from level flight Z axis should work ok- i've got it reading to a 'speedbar' atm but only in integers (that's all i needed
)
