14 CFR Ch. I (1-1-19 Edition)

The recorded values must meet the designated range, resolution and accuracy requirements during static and dynamic conditions. 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.

Remarks

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 alternately once per second
to produce the sampling interval of 0.5 or 0.25, as applicable.

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

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 alternately once per second
to produce the sampling interval of 0.5.

For airplanes fitted with multiple or split surfaces, a
suitable combination of inputs is acceptable in lieu of
recording each surface
separately. The control
surfaces may be sampled
alternately to produce the
sampling interval of 0.5 or
0.25, as applicable.
A suitable combination of
surface position sensors is
acceptable in lieu of recording each surface separately. The control surfaces
may be sampled alternately to produce the sampling interval of 0.5 or
0.25, as applicable.
