Electromagnetic interference suppression. The vehicle shall be equipped for the suppression
of electromagnetic interference in accordance with Part 8 (Group I) of MIL-STD-461 as modified below. As
a minimum, the bandwidths listed below shall be used in the appropriate frequency band of the measure-
ment receiver for UM03 testing.

d levels. The maximum sound level produced by the vehicle shall not exceed 84dBA
3.1.8
when tested in accordance with 4.6.7.7 An additional 2dBA allowance shall be permitted for production
units to provide for variation in test site, temperature gradients, test equipment, and inherent differences
in nominally identical vehicles.
3 . 1 . 9 A i r t r a n s p o r t a b i l i t y . The vehicle shall be air transportable without shoring in accordance with
MIL-STD-1791 in Types C-130, C-141, and C-5 Aircraft and shall be air transportable in a Type C-17
Aircraft Preliminary design guidelines for the Type C-17 are 142 inches maximum height, 204 inches
maximum width, 812 inches maximum length, 9 ramp angle, and floor load capacity equal to that allowed
for the Type C-5 Aircraft.
3 . 1 . 9 . 1 T i e d o w n s . The vehicle shall be equipped with sufficient tiedown points so located that it can
be restrained in all directions during air transport. The attachment points shall be designed for use with
attachment in the aircraft as described in MIL-STD-1791. Sufficient clearance shall be maintained around
all attachment points to allow for restraining chains without interference from any other structure. The
tiedown points shall have a minimum clear opening of three inches to allow attachment of a chain with a
grabhook.
Documentat ion and certification All documentation and certification shall be available at the
3.1.10
first article contractor test (see 4.4), and upon request, be furnished to the engineer during the tests
a Required certification from OEMs.
