(c)
Locate points on the graph for a minimum weight airplane at maximum and minimum CG for your tire-to-ground friction conditions.
(d)
Interpolate between the two CG's to determine the wind speed for a minimum weight airplane at your CG, friction coefficient and brake conditions.
(e)
Use the weight of your airplane to interpolate wind speed between maximum and minimum airplane weight wind speeds at your CG, friction coefficient and brake conditions.
(f)
Wind speeds above the one you identify will require the airplane to be moored or the parking brake to be set. Wind speeds below the one you identify do not require the airplane to be moored.

CAUTION: DO ALL OF THE STEPS THROUGH THE PARAGRAPH FOR WIND GUST THAT
_______ ARE 70 KNOTS OR HIGHER. THIS IS WHEN WHEN THE AIRPLANE IS PARKED WITH ITS TAIL IN THE HANGAR. WHEN THESE STEPS ARE NOT DONE, THE AIRPLANE CAN MOVE AND CAUSE DAMAGE TO THE AIRPLANE AND THE HANGAR.
(4) When the airplane is parked with its tail in the hangar, do the step that follows:
(a) Do all of the steps through the paragraph for wind gusts that are 70 knots or higher.

D. Wind Gusts That Are Between 34 Knots and 40 Knots
S 582-004
(1) When the wind gusts are 34 knots or higher, do the steps that follow:
(a)
Put the flaps to fully up (do this unless the airplane is in maintenance).
(b)
Put the stabilizer at 1.5 units of trim (do this unless the airplane is in maintenance).
(c)
When workstands are necessary, do the steps that follow: 1) Apply the workstand brakes 2) Put the workstand pads down 3) Put wheel chocks around the workstand wheels when it is
necessary.
(d)
Remove all workstands that are not necessary.
(e)
Remove all ladders that are not necessary.
E. Wind Gusts That Are Between 40 Knots and 50 Knots
S 582-005
(1) When the wind gusts are more than 40 knots, do the steps that follow:
NOTE: Also do the steps for wind gusts that are greater than
____
34 knots.
(a)
Make sure the airplane gross weight is correct.
(b)
Make sure that the brake pressure is not less than 1500 psi (the brake pressure gage is found on the first officer's panel).
(c)
Make sure the parking brake is set.
(d)
Make sure the torsion links of the nose landing gear are connected.
(e)
Make sure the towing lever lockpin is removed.
F. Wind Gusts That Are Between 50 Knots and 60 Knots
S 582-006
(1) When the wind gusts are more than 50 knots, do the steps that follow:
(a)
Make sure the flaps are fully up.
(b)
Make sure the stabilizer has 1.5 units of stabilizer trim.
(c)
Put all hydraulic hoses away.
(d)
Put all electrical cables away.
(e)
Close and latch:
1) All windows
2) All external doors
3) All access panels.
(f)
Move all of the support equipment away from the airplane. This includes: 1) The work stands 2) The ladders 3) All other objects you can move.
