757 MAINTENANCE MANUAL
 PARKING IN HIGH WINDS - MAINTENANCE PRACTICES
_____________________________________________
 1.  General_______
 A.  This section gives the instructions to make sure the airplane stays in its position while it is parked in high wind conditions. These instructions are to be done along with the normal parking procedure (Ref 10-11-01).
 B.  When the airplane is in the correct configuration, it will be resistant to 135-knot winds. This is when the airplane is pointed directly into the wind.
 C.  On a dry surface, the airplane will be resistant to 100 knot side winds.
 D.  On a wet surface, the airplane will be resistant to 90 knot side winds.
 E.  This procedure is for an airplane that has all of its weight on the landing gear (not lifted on jacks).
 F.  The nose of the airplane must be held both vertically and laterally. The vertical tiedown must be applied to the upper shock strut. The lateral tiedown can be applied to either the upper or lower shock strut. The recommended location is at the tow fitting on the lower shock strut.

 (3)  Make sure the airplane gross weight and center of gravity (cg) is correct for the anticipated wind gust velocity and ramp surface condition (Fig. 203):
 NOTE:____You can get this load with different configurations. Use different configurations of fuel in the main and wing tanks, and ballast in the lower cargo hold. Use the Weight and Balance Manual to calculate the correct loads necessary to get the specified airplane weight and balance condition.
 (a)  Locate points on the graph for a maximum weight airplane at maximum and minimum CG for your tire-to-ground friction conditions.
 NOTE: Unless other friction data is available, use the
