Roll Control

.....................

For underdamped systems: 

±

10% of time from 90% of 

initial displacement (0.9 

A

d

) to first zero crossing, 

and 

±

10 (n+1)% of period 

thereafter. 

±

10% ampli-

tude of first overshoot, ap-

plied to all overshoots 

greater than 5% of initial 

displacement (.05 A

d

), 

±

1 

overshoot (first significant 

overshoot must be 

matched). For over-

damped systems: 

±

10% of 

time from 90% of initial 

displacement (0.9 A

d

) to 

10% of initial displace-

ment (0.1A

d

). For the al-

ternate method see para-

graph 4 of this attach-

ment. The slow sweep is 

the equivalent to the static 

test 2.a.2. For the mod-

erate and rapid sweeps: 

±

2 lb (0.9 daN) or 

±

10% 

dynamic increment above 

the static force.

Takeoff, Cruise, and 

Landing.

Data must show normal control displace-

ment in both directions. Tolerance ap-

plies against the absolute values of 

each period (considered independ-

ently). Normal control displacement for 

this test is 25% to 50% of the max-

imum allowable roll controller deflec-

tion for flight conditions limited by the 

maneuvering load envelope.

X 

X 

‘‘n’’ is the sequential 

period of a full cycle 

of oscillation. Refer 

to paragraph 4 of 

this attachment for 

more information. 

Static and dynamic 

flight control tests 

should be accom-

plished at the same 

feel or impact pres-

sures.
