MIL-D-23222A(AS)
3.7.1.2
OPERATION OF APPURTENANCES. - During developmental
flights at the contractor's plaint, appurtenances
which can be put into continuous motion (such as rotation of radar
antenna), or which can be extended or rotated to different positions
(such as an extensible hoist or sonar), or which can be extended and
retracted (such as an extensible ramp door or landing gear), shall
be operated sufficiently to determine, by a combination of test data
and calculations, the effects on helicopter loads and motions up to
the limits required for structural design  of the particular items.
These determinations shall be discussed fully in the Demonstration-Planning
and Progress-Report after which, selections will be made of the posi-
tions and motions of appurtenances required fOr dives and pull-outS,
if such positions and motions are not specified in Table 2. During
each flight and immdiately subsequent to each flight performed in
compliance with the requirements of paragraph 3.7.2.2, the satis-
factory operation of extensible ramp doors, or other appurtenances
subjected to water  loads as applicable, shall be demonstrated.
3.7.1.3
ALTERNATE GROSS WEIGHTS. - Alternate gross weights
may be approved in writing by the test authority
for any or all of the test conditions specified provided that conpli-
ance is made with both of the following:
The load factors attained and the magnitudes and
(1)
distributions of weight employed are such that
all parts of the helicopter will be loaded at
least as critically as they would be loaded if
the tests were made at the specified gross weights
and center-of-gravity positions.
(2)
The products of load factor times gross weight
attained in dives and pull-outs are not lower
in absolute value than those specified.
