The recorded values must meet the designated range, resolution and accuracy requirements during static and dynamic condi-
tions. Dynamic condition means the parameter is experiencing change at the maximum rate attainable, including the maximum
rate of reversal. All data recorded must be correlated in time to within one second.

For airplanes that have a
flight control breakaway
capability that allows either
pilot to operate the controls
independently, record both
control inputs. The control
inputs may be sampled al-
ternately once per second
to produce the sampling of
0.5 or 0.25, as applicable.

For airplanes fitted with mul-

suitable combination of in-
puts is acceptable in lieu of
recording each surface

surfaces may be sampled
alternately to produce the
sampling interval of 0.5 or

A suitable combination of
surface position sensors is
acceptable in lieu of re-

may be sampled alter-
