"Marco Leon" mleon(at)optonline.net If any are reading, what are you all doing with your aircraft to make it ready for the storm? 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." Russell Kent |

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... Marco "Ron Natalie" wrote in message . .. "Marco Leon" mleon(at)optonline.net wrote in message ...

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). |

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. 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.

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 That was "Floyd". Who could forget the pictures of pigs on the barn roofs? Whole houses and coffins floating down the street. I was here for Fran too. The roar was incredible, but the silence of the eye was downright eerie. Here in NC, it's usually not the speed of the wind that causes problems, it's the falling trees/branches. People were killed when trees landed on their cars while they drove. Whole houses were destroyed when multiple trees crashed through the roof. A rescue worker was killed yesterday when he drove into a fallen tree. I was nearly taken out by a fallen tree that came through my windshield during TS Josephine, missed my forehead by an inch. So at the airport, as long as there are no trees nearby, I would be more afraid of flying roof materials and flying debris. A piece of corrugated steel zipping along at 60 mph could do real damage. Also, low-lying airports get flooded out. My old airport (5W5) always got flooded out during storms, so Fran and Floyd really did a number on the planes that were unfortunately left there. I think even some of the hangared planes had water damage. The best option is to get your plane the heck out of Dodge. -Trent PP-ASEL |

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). My PA28-180 was tied down at RDU and survived Fran just fine. Ditto for Floyd. This time (Isabel) the Mooney went into Southern Jet's brand new maintenance hangar, along with as many other aircraft as could be shoehorned in there. The sight of all those airplanes crammed in there with a hurricane on the way must have given the insurance companies shivers. The "other one" that ran thru here to the That was "Floyd".

Bingo. It's all about the trees. So at the airport, as long as there are no trees nearby, I would be more afraid of flying roof materials and flying debris. A piece of corrugated steel zipping along at 60 mph could do real damage. Also, low-lying airports get flooded out. My old airport (5W5) always got flooded out during storms, I remember well the pix of the flooding at 5W5. Really sad to see all those perfectly good airplanes underwater. I wonder what happened to all of them. Were they totalled by the insurers? Restored? Scrapped? There were plenty of flood - damaged cars on the market here in NC after Floyd. I guess there's no record for airplanes like there is for cars that would warn you that you are buying a flood damaged airplane. so Fran and Floyd really did a number on the planes that were unfortunately left there. I think even some of the hangared planes had water damage. The best option is to get your plane the heck out of Dodge. Maybe. I remember the (apocryphal?) story of the guy that flew his 172 up to Raleigh from Wilmington to get it out of the way of Fran. Unfortunately for him, Fran pretty much skipped Wilmington and went right over Raleigh. His airplane was one of 2 or three that were damaged at RDU. Remove SHIRT to reply directly. Dave |
