..........
A rudder step input of 20%–30% rudder
pedal throw must be used. Not required
if rudder input and response is shown in
Dutch Roll test (test 2.d.7.). CCA: Test
in Normal and Non-normal control
states.

..........
May be roll response to a given rudder
deflection. CCA: Test in Normal and
Non-normal control states.

May be accomplished as a
yaw response test, in
which case the proce-
dures and requirements
of test 2.d.6.a. will apply.

Landing.
Record results for at least 6 complete cy-
cles with stability augmentation OFF, or
the number of cycles sufficient to deter-
mine time to
1

CCA: Test in Non-normal control state.

Approach
or
Landing
..........
Use at least two rudder positions, one of
which must be near maximum allowable
rudder. Propeller driven airplanes must
test in each direction. May be a series
of snapshot test results. Sideslip angle
is matched only for repeatability and
only on continuing qualification evalua-
tions.

One test is required in each axis (pitch,
roll and yaw) for each of the three con-
ditions (take-off, cruise, and approach
or landing).
