HBC Parking Into The Wind

[DanH]

After the Big Storm on Saturday evening, conversation again turned to parking HBC with the airplanes facing west, into the prevailing wind, where all the nasty weather comes from. In effect, the most recent storm subjected the whole fleet to a 50~70 mph tail slide, and it seems like it happens every year. There were more than a few damaged airplanes, in particular A-model RV's.

The subject has been brought up by board members and others in the past, without success. Tradition dies hard at OSH, where airplanes have always been parked facing show center, except for the North 40, where they nest nose/tail to pack them in. Jack Pelton was due at the HBC pavilion Sunday evening to dedicate it to Van (entirely deserved!), so a plan was organized to solicit his support with some crowd encouragement...after proper prep via channels. The upshot was the question didn't require audience participation. I spoke with him, he knew the deal, and (I quote) "It's your fly-in. Tell the parking chairman what you want, and that I support it". Being me, I pushed a bit, asking "Can I tell him you said get it done?" The response was a clear "Yes".


That said, there are right and wrong ways to do everything. I think as a group, we greatly respect the volunteers who do the hard work, and nobody, including me, is going to be silly enough to tell them what to do. That probably includes Jack. Change will require consensus.

As Mr. Pelton said, it's your fly-in. If you want to park facing west next year, let's hear it. If not, let's hear that too. Either way, consider the greater good.

Put me down as a "yes" to parking into the wind please. I dodged a bullet this year with the Saturday storm. I had my gust lock installed (it normally works very well), but sometime during the storm it slipped off somehow (it's and Anti-SplatAero design that locks the stick and rudder pedals together). Luckily my RV-10 didn't incur any damage, but it just as easily could have been a disaster.

Dan,

As we discussed at the show, this idea is under serious consideration for next year among those of us in charge of the parking arrangements. We spent some time later in the week scoping things out and taking measurements to get a better handle on exactly what it would take to make it happen. Short version is that we could do it with reasonable efforts, mostly involving relocating some fences and remarking some burn lines.

Before making any significant change, it is a good idea to carefully think things through and not just make a knee-jerk decision. Always beware the law of unintended consequences. Just to get discussion going, here are is some food for thought:

Parking into the wind may be best for nose-gear RVs, but what about other types? Does pointing into the wind increase the risk for say a tailwheel RV, a canard aircraft, or a Cub-type which is now exposing it's high-lift airfoil to 60 MPH winds and straining it's tie downs beyond the failure point? A few years back we had an aircraft in HBP get ripped loose from it's tie downs in a storm and deposited upside down on top of the aircraft parked next to it, so it can happen. Does parking facing west increase that risk? Or the less extreme example of one being pulled loose from it's tie downs and pivoting into the adjacent aircraft, which has also happened.

We have 11 months to hash this out and come to a decision, so let's have the conversation.

Jeff, is there any data from the North 40, even if anecdotal? They park both ways.

I dunno, but I know who to ask. Stand by for further…

To lift an idea from "The Hunger Games", I think the odds would always be in our favor parked into the wind.

1) In general, aircraft would be facing the prevailing winds and control surfaces would typically be in trail, reducing the chances of them getting slammed around.

2) I think both nosegear and tailwheel aircraft, properly secured, won't go anywhere in strong headwinds. The aircraft I've seen wrecked at Oshkosh were all turned away from the wind and when the tail broke loose, bad things happened. Obviously, there are no guarantees that aircraft will be properly secured, but I think the odds are generally improved with the aircraft facing the wind.

Aside: The nice little Sopwith Pup replica parked at the Replica Fighter Association HQ actually broke loose during the storm. I don't know why it didn't get shredded, but we walked up on it that evening, repaired the broken rope that had previously held the tail and tightened the ropes attached to the wings. The aircraft was secured by "the claw" and whoever tied it down didn't follow the instructions on how to use that system. Maybe someone needs to walk the field an hour after aircraft arrive and give tie-down guidance. There are people who could use help there...

Tradition, ". . . airplanes have always been parked facing show center, . . ."

I guess that makes some sense if you sit in your plane while the airshows are being performed, if you must follow tradition sit in a chair facing show center.

I would rather respect the direction of strong winds and face the spinner into the wind (storm winds generally from the West) to reduce the chance of damaging my airplane.

As was said by Jeff, you are free to position your plane whatever direction you feel is best in your assigned parking site.
I saw a picture somewhere of a rudder lock on some cargo planes that clamped the rudder to the VS wrapping around them about mid point. It is heavier and may not be the easiest to carry but I imagine a cargo company know what works.

Facing into the wind creates lift on the wings and tail because of the positive angle of incidence, and strains the tie-downs. Especially for taildraggers, but also nosedraggers. Facing away from wind presses the airplane down--isn't that what you want?

South of Boeing Plaza most, but certainly not all, of the planes are parked facing North or South, so they always deal with crosswind issues. HBC most are East/West facing. The variety of parked aircraft positions facing all the compass points has existed at Wittman for decades now. I wonder if anyone has done a study of damage to see if there is a correlation with direction parked?
