2.d.3.a. .......

Lateral-Directional Oscillations.

Section0.5 sec. or Section10% of period,
Section10% of time to 1-2 or double amplitude or Section0.02 of
damping ratio, Section20% or Section1
sec of time difference between peaks of bank and
sideslip. For non-periodic
responses, the time history
must be matched within
Section10 knots Airspeed; Section5Section/s
Roll Rate or Section5Section Roll Attitude; Section4Section/s Yaw Rate or
Section4Section Yaw Angle over a 20
sec period roll angle following release of the controls.

Cruise or Climb. Augmentation On and Off.

Record results for at least
two airspeeds. The test
must be initiated with a cyclic or a pedal doublet
input. Record results for six
full cycles (12 overshoots
after input completed) or
that sufficient to determine
time to 1-2 or double amplitude, whichever is less.
The test may be terminated
prior to 20 sec if the test
pilot determines that the results are becoming uncontrollably divergent.

2.d.3.b. .......

Spiral Stability.

Section2Section or Section10% roll angle.

Cruise or Climb. Augmentation On and Off.

Record the results of a release from pedal only or
cyclic only turns for 20 sec.
Results must be recorded
from turns in both directions. Terminate check at
zero roll angle or when the
test pilot determines that
the attitude is becoming
uncontrollably divergent.

2.d.3.c. ........

Adverse/Proverse Yaw.

Correct Trend, Section2Section transient
sideslip angle.

Cruise or Climb. Augmentation On and Off.

Record the time history of initial entry into cyclic only
turns, using only a moderate rate for cyclic input.
Results must be recorded
for turns in both directions.

Based on Simulator Capability.

N/A .........................................

Required as part of the
MQTG. The test must demonstrate frequency response of the motion system as specified by the applicant for flight simulator
qualification.
