aerial off loading

Other then quite a few apple cores and banana peels, I don't have a lot of experience with dumping things out of airplanes.

A local group of back country skiers and snowboarders have asked me to deliver a 60 lb. canvas teepee to a site on the backside of the range my place is on. Right on the other side of the mountain pictured in my avatar as a matter of fact. I got plied with a free lunch at the best local Mexican resturant, and agreed to give it a shot. The easiest way would be to remove the doors (less then a minute for both) and throw it on my smooth plwood cargo deck, that takes the place of my rear seat when needed. I could tie off the load in such a way that I could untie it while flying, and then simply lower one wing and cross control, flying straight sideways in effect, and let it slide out on the smooth plywood deck. I have no clear concept of where the horizontal stabilizer would be when this would be happening, hopefully still attached to the airplane, yeah, but without getting into Newton's Law, is it going to drop fast enough to avoid hitting the rear hor. stab, that is the question???! Egress speed would be about 50 MPH. It would be hog tied every which way, so that it couldn't inflate or catch air.

The other way would be to ratchet strap it to the belly, (I'd have to pull my swiss muffler for this, no biggie) and then get some cheap Harbor Freight light duty (I already said Harbor Freight I guess) ratchet straps, two of them, going clear around the fuselage and sucking the load up against the belly. The problem there is I'd have to devise a way to cut both straps at the same time to get it drop clear all at once. I don't believe using just one strap, that the load would be secured properly. Even if it fell of too soon or unexpectantly, this method would be safe for me and the plane. But, it would be awfull draggy in flight.

I'm open to suggestions, telling the back country dweebs to hike it back there themselves I've already thought of BTW. Hey, this group could very well come in handy for me if I have a problem requiring some help, and I will be back there on my wheel skis this winter. These would be the first guys I would call, so I really want to make it happen. Ideas?

Re: aerial off loading

Flaps 1 or 2 notches, flying 50kts, the bundle is secure, no parachute, It will fall down and not aft to the tail. Not that you dont know this but. Know your plane. Low airspeed, low altitude, one hand on the stick and eyes back at the payload.

Re: aerial off loading

Plan A wouldn't bother me a bit about hitting the tail. I would ensure there is nothing to catch or hang up on the door, step or interior. It looks like I can see some sort of string cinch for the bag? Loose fold of the sack in a pinched spot somewhere etc. A partial deployment is bad news. Oh and double sure your DZ is clear so if it comes out early or late it's no factor.

We were excited to heli in Silverton — until we saw the bird. Looking like something your stoner uncle built in the garage out of four Meccano sets, a fish tank, and an AMC Pacer, this helicopter seats a pilot plus two only, making it a tricky vehicle, logistics-wise, when your group has 8 people in it.

you dont need to slip just reach around behind grab the package and roll it out the door. works with compressed hay bails from a supercub anyhow.

Re: aerial off loading

Make sure you have a damn good knife you can get to quick just in case. If one of those straps gets hung up it will be interesting.

Re: aerial off loading

There are enough things that can bite us aviators without experimenting with offloading while low and slow. If these folks were stranded down there and needed gear for survival that would be one thing but doing this just to be a cool guy wouldn't interest me much.

Re: aerial off loading

That little 60lb bag is NOT going to affect you.

We bail out of 180's. 182's , 185's, 206's, 207' etc., all the time. The load goes straight down. There is a brief moment of the load "going over the hill" so to speak, (it will appear to fly along the plane with you very briefly) as it falls away.

JUST MAKE CERTAIN ALL STRAPS ARE TIGHT WITH NO OPTION FOR HANG UPS. Horzontal is not a factor unless you have a hang up.

By the looks of that little white bag, you good to go. Very simple...Go get your dinner.

Make them think its very very difficult and get unlimited Margs out of the deal as well for you and your gal.

Won't be slow, 50 for me and my bird isn't slow, around about 35 mph I'm thinking it is just starting to get slow, and it isn't REALLY slow until under 30, and I spend a lot of time (while landing and away from any built up structures and/or people.....) down low, I won't be doing anything different there. I like and admire this group of hooligans who are incredibly fit (not much hanging out in the local bars with this crowd), have known them for a few years, and really, they would be the first group to help me if I have a problem back country flying in the same area. I just wanted some feedback by others experienced in the dynamics of an aerial drop. Also, the first hand knowledge and experience gained by me in doing so could very well come in handy in the future, as in if it WAS an emergency situation, think of this as a test drop for when I really need to do it.

I stuck my head out the back door a half hour or ago to check the weather for tomorrow, looking better! The area in question (drop zone) is maybe 3 or 4 miles at most away, up over the 9K range from my 5K location, at the 8K area, we are looking at Sunday, weather permiting of course,for the drop. I'll see if they can video it, but it will probably look pretty boring. As far as the accuracy of the drop, well, I did win the flour bombing contest at the flyin at Three Forks Montana this year!Image

Good thinking there! I'll start building it up as in being incredibly difficult/dangerous etc etc...!

In the meantime I'll secure it into a solid lump of canvas, what you see is how they delivered it, just two cinch straps so they could throw it in the pickup, I'll rope the heck out of it, (using a truckers hitch) and keep any knots on top. My already built and in place aux cargo deck is perfect already, no obstructions whatsoever, that sucker should slide right out, piece of cake. I'll take a knife also, probably a box cutter with a fresh blade. Good thing I don't have to go through security at my strip.

Re: aerial off loading

The champ, the old Coyoteie, and my self went aviating around to eventually arrive a ranch of some friends. When we over flew we noticed they were playing football, this is a factor that rears it’s ugly head later.
We landed and being the bull shitters we are, we managed to spend the next copula of hours shooting the breeze. Cutting to the chase, the old Coyote smuggled the football back on board to be used for a bombing run on departure.
We took off and on the departing pass, he rolled slightly over and did his level best to spike one of the unsuspecting targets. While he was trying to access the results I happened to glance out the windscreen. I immediately realized every thing was GREEN, and in the school girl voice I started screaming…… PULL UP, PULL UP, PULLLLLUPPPPP. You know if there wasn’t all that crap hanging down, a Champ would make a great hedge trimmer. Small branches and leaves were going every direction, there was even evidence left hanging on the gear when we got home.
The moral to the story is, “as soon as you drop, start paying attention to where you are going.” Good Luck!

While aviation has made the world a smaller place, if you fall, it's still hard to miss!

Re: aerial off loading

I would think with your ability to T/O and land that thing, you could find a spot to land, and hand it to them, but that wouldn't be any fun/challenge :lol: . Enjoy the meal/margs

If you want to go up, pull back on the controls. If you want to go down, pull back farther.

Re: aerial off loading

You could always do the missionary aerial winch thing. They would circle and lower things through the jungle openings with a rope attached to a winch. Some how the rope stayed in a relatively small spot while the plane made it's 360's. They also picked things up this way. There was a DVD trailer showing this called "Point of the Spear".

Re: aerial off loading

For sure there is no place to land up there. Too rough and too much brush, trees etc.

A 60 lb. bucket trick, that may be be bit much for my little bird!

It looks like today, weather finally cleared. The drop off point is closer then I thought, directly behind my place, I can see it out the kitchen window! 3500' higher. Handy anyway......
