In ground vehicles, vertical velocity within the
b.
range of 0 to 15 miles per hour up or down. While being
transported by helicopter, vertical speed within the range of 0
to 2400 ft/min.
c. Acceleration (excluding shock and vibration) within
the range of 0 to 1.5g (not including gravitational
acceleration) in any direction due to vehicle starting, stopping
and turning.
Vehicle pitch within the range of -40 to +40 degrees.
d.
Vehicle cant/roll within the range of -40 to +40 degrees. The
relationships of vehicle pitch and cant/roll axes to DRU case
coordinates may vary from installation to installation.
e. Angular velocities within the range of 0 to 200
degrees per second around any axis.
f. Angular accelerations within the range of 0 to 6000
degrees per (second squared) around any axis.

3.6.1.5.2 Deployment. In addition to operating when
subjected to the above vehicle dynamics, the DRU shall perform as
specified herein when operated under the following conditions:

angle of 105 degrees or rotated 360 degrees in azimuth when the
pointing device is erected.
