If any are reading, what are you all doing with your aircraft to make it

Interesting question. Nothing here in Durham. The Maule is in the hangar.
I expect to lose power for a few days so that puts the Maule out of
commission since I have no other way of raising the electric door. We're
leaving town - it's thrilling but not fun to sit thru that stuff.

Talked to the airport manager. They are policing the tiedowns for loose
materials. I assume a few people have flown out but can't tell.

We expect up to 50 knot winds...

I was hear during Fran and "the other one". Fran ran dead center thru the
RDU triangle area. You never forget the roar of the train. It was real bad
but I don't remember any a/c loses here at 8NC8 (was W65). The "other one"
that ran thru here to the east caused extensive freshwater flooding that did
more damage than the winds of Fran. I flew over a few days later to an
airport using the GPS (either ETC or MCZ). Couldn't spot it until I
realized the underwater rectangles were wings of tiedowned aircraft. There
was a runway shaped oil slick on the water which appeared to be over 8 feet
deep. Everything east of I-95 seemed submerged.

How sturdy is the hangar? Stories from this newsgroup indicate that there's
a certain level of risk with the structure collapsing on top of the plane.
Are there any building codes that hangars can follow?

The manuevering speed on my Warrior is 111 kts which translates to about 128
mph. Theoretically, as long as there's no foreign object damage and the
winds are below that number, it should do fine in a secure tiedown. Someone
comment if they think I am wrong in my assumption (won't be the first time).
I'm in NY and we're anticipating on 50 mph winds though.

Good luck with your Maule!

I believe the manuevering speed is predicated on the assumption that the
relative wind is coming from within a few degrees of straight ahead. I don't
think a 128 MPH 90 degree crosswind would be "fine in a secure tiedown."

Manouvering speed isn't a reasonable number to use here. What manouvering
speed does is say that you a full control input will stall you before you exceed
the loading limits (also note that the stall comes at higher speeds when you are
not at the gross weight so the manouvering speed is lower than the 111 knots
indicated above). This is not an issue of control deflection. Your plane is
not stalled, and not going to stall as it's attitude is artificially constrained.

The question is whether the tiedowns and what they are connected to on your
plane can take the aerodynamic forces. Also note that you're not necessarily
going to have the wind coming head on to the nose.

Your points make total sense. Points well taken. I will not use that number
anymore. It does beg the question though of WHAT it can really take. I don't
believe any tests are required or have been done for most aircraft so we
really can't be sure. Maybe I should start worrying about the 50 kt winds
after all...

Last time there was a major landfall of a huricane in Florida, almost all
of the schemes including putting spoiners on the wings were found to
be largely ineffective. Evacuation is the best suggestion (a little
late for that now).

Dunno about the logic - that's intended to prevent damage due to turbulence
and may have nothing to do with the strength of the tie-down rings. In any
case, my Maule has gone through one storm with 90 mph winds on tiedown at 47N
and I expect it to get through this one ok (I went out this morning and made
sure it was secure).

Prior to that, I owned a Cessna 150 that made it through two nasty storms on
tiedown. Winds of one of those storms were measured at 120 knots in NYC.

My standard procedure is to run extra tiedown ropes to the wing struts (you
might want to tie off to the gear?). I also make sure that any loose strap ends,
such as those on my covers and the "remove before flight" tag on my pitot cover,
are secured so they won't whip in the wind. Still, there are a lot of planes
at Kupper that didn't take any special precautions and came through those storms
just as well as my planes did.

Not for Marco, if he hurries. He's in New York, and the weather is still VFR
here in New Jersey. In fact, it looks like the winds would make it a fast run
if you headed west, though taking off would be interesting - winds in the area
are reported to be in the teens with gusts in the mid 20s at the moment.

Oh, I was paying attention to the subject line (NC).
