3.f.4.
..............
Buffet with speedbrakes
deployed.
Simulator test results must
exhibit the overall appear-
ance and trends of the air-
plane data, with at least
three (3) of the predomi-
nant frequency ‘‘spikes’’
being present within
±
2
Hz.

3.f.5.
..............
Buffet at approach-to-stall
Simulator test results must
exhibit the overall appear-
ance and trends of the air-
plane data, with at least
three (3) of the predomi-
nant frequency ‘‘spikes’’
being present within
±
2
Hz.
Flight
............................
The test must be conducted for ap-
proach to stall. Post stall characteris-
tics are not required.

3.f.6.
..............
Buffet at high airspeeds
or high Mach.
Simulator test results must
exhibit the overall appear-
ance and trends of the air-
plane data, with at least
three (3) of the predomi-
nant frequency ‘‘spikes’’
being present within
±
2
Hz.
Flight
............................
X
The test may be con-
ducted during either
a high speed ma-
neuver (e.g., ‘‘wind-
up’’ turn) or at high
Mach.
3.f.7.
..............
In-flight vibrations for pro-
peller driven airplanes.
Simulator test results must
exhibit the overall appear-
ance and trends of the air-
plane data, with at least
three (3) of the predomi-
nant frequency ‘‘spikes’’
being present within
±
2
Hz.
Flight (clean configura-
tion).

4. Visual System.
4.a.
................
Visual System Response Time: (Choose either test 4.a.1. or 4.a.2. to satisfy test 4.a., Visual System Respo
nse Time Test.
This test also suffices for motion system response timing and flight deck instrument response timing. Motion onset should
occur before the start of the visual scene change (the start of the scan of the first video field containing different informat
ion)
but must occur before the end of the scan of that video field. Instrument response may not occur prior to motion onset.

tion in this attach-
ment; also see
