The vibration limits for
transport in a turbo
propeller aircraft (3g peak
acceleration from 50 to 500
Hz) apply. The System
Controller was tested on all
three axes, 10 minutes per
axis.

(Hz) (g) octave/min
5–50 0.5 0.1
50–500 3.0 0.25
Resonant dwell: the System
Controller will not be damaged
as a result of a 0.5 g (0 to
peak) resonant search, from 5
Hz to 200 Hz at a sweep rate
of 1 octave per minute,
followed by a 5 minute dwell
at package resonance.
