Get a sturdy tail Stand!!! This is the critical factor. If you do not
reduce the lift produced by the wing, your likelihood of keeping the
glider on the ground are very poor, no matter what else you do.
Getting the wing at (or below) a zero degree angle of attack (A.O.A.)
dramatically increases your odds of keeping the ship on the ground,
especially something as light and tall as a 2-33. In a 2-33, the
A.O.A. with tail on the ground is very close to max lift - definitely
NOT what you want. This was/is standard procedure at most of the
professionally run gliders ops in the US and is discussed at length in
the old Schweizer red "bible".

Deploy drag devices and place flaps full negative, if available.

4 ft screw-in anchors are not adequate. Effective tie-downs involve
a 4+ ft hole in the ground that is belled out at the bottom and then
filled with concrete with a 2 ft long (each leg) Omega-shaped piece
of rebar set in them. Screw-in anchors are notorious for failing in
many different modes (snap, pull out, bend,). Oshkosh sees this
happen yearly.

One can backup the ropes tiedowns with chain, though not my preferred
solution; it puts too much shock load on the glider for my tastes.

Tiedowns should include: tail, nosehook, and inboard and outboard
wings. Not not forget gust locks (tied on) for ailerons, rudder, and
elevator.


A "combat" solution is to park something large and heavy (very heavy)
upwind of glider. Large dump trucks are useful.


Some very windy/rowdy places such as Tehachapi, California City, and
some airports in the southern Appalachians and Colorado have had very
few losses to wind using these strategies. Of special note is
Tehachapi where they have had 3-6 2-33's tied down for more than 25
years with NO wind-related losses. Tehachapi only uses tow rope as
tiedown material and its breaking strength is only 1200 lbs. Clearly,
they are not putting large loads on the ropes!


Significantly, wind and rotor in excess of 80 mph have been recorded
there and such conditions occur on an annual basis. Perhaps there is
a reason there are 5000 wind turbines just downwind of the
airport???

Don't reinvent the wheel! Use these proven methods. Get the nose
down, spoilers out, put in some sturdy tiedowns, and sleep better at
night!
