Twistline

What would be the canopy size or load, that you start getting those ugly spinning line twists?

Line twists are usually a result of bad body position during the deployment sequence. While I'm not an instructor, so take my advice, well, don't take my advice, but what I've heard and been told is that the really ugly, spinning line twists are more likely to occur (and be worse) on small canopies. The smaller the canopy, the more severe line twists can be.

Again, I don't know how true it is, I'm only saying what I've heard. I do know that I'm sure I've had a few bad body positions on the larger student canopies and I haven't had a line twist on them. I have, however, had two instances of line twists on my own canopy, which is 160 square feet. Both were very minor (one twist) and I was out of them almost instantaneously.

Because of my body position I have had 2 linetwists with no problems since I used a PD-260 but all I know is that with big canopy less chance to start spinning, but what would be for smaller the regular size or load to get more frequent spins under a linetwist any one know?

Or when the corner of the bag hits the pack tray. All depends on how you put your bag in your container. Just a little trick I learned from Brian Germain

There is no one size where line twists become spinners. Canopies become more sensitive the smaller and more elliptical they get but you can't say what size will spin and what size won't.

For example I have had linetwists on a Sabre2 150 that flew dead straight, but I know a student (lighter than me) who had spinning linetwists on a 260 that she cut away from.

Do you want to have an ideagasm?

I learned also, if the lines next the the reserve tray actually go under the reserve tray, it could cause the d-bag to spin on deployment because one side of the lines may get out of the container before the other (not sure if that made sense or not, lol)

But, a lot of it, IMO, has to do with body position more than pack jobs on big docile canopies like mine. I fly a 190 with a WL of about 0.97 and I've had 6 twists one time and 8 another time. Basically that was due to rusing to pull. Now I take my time to make sure I don't drop a shoulder when I pull. And I've started to "steer" the canopy out of twists on opening. If I see that it's going to twist, I just pull a little on a riser to correct that.

I know on my canopy, a Triathlon, that major line twists usually don't cause too much of a problem. Canopy flies straight and doesn't dive. However, I've seen videos of a Spectre, loaded at 1.2, that started spinning pretty quickly...

So, it all depends I guess on the situation.

Line twists on square canopies are usually not a reason to cut away unless they are very numerous or above the slider (rare). Elliptical canopies, on the other hand, are more likely to "spin up" and require a chop. Higher wing loadings increase the likelihood that the pilot cannot kick out of them.

Linetwists are merely a nuisance under my Velo, unless its pointed at the ground and Im pointed at the sky.

Id take what you said a bit further by saying that the classification 'nuisance' also comes with orientation of your flight, and available altitude.

To respond to the origina poster: I had plenty of line twists in my early jumps. I even had my sabre I 170 spin up so bad the risers pinned my chin to my chest. Ouch. Packing and body position play an important role, work with your instructors on how to best attempt to prevent line twists.

I have had only one instance of line twists, and I was spinning like a mad man on my second aff when I whipped it out.

(And now I am going to have 30 in a row)

Ugly spinning line twist are really rare on student canopies, because they are designed to not suffer that type of malfunction.
Rather, student canopies are designed to solve their own line twists, that is why the majority of student canopies are square (Falcon, Manta, Skymaster, etc.)or slightly tapered (Aerodyne Solo, Icarus whatchamacallit, PD Navigator, etc.).
Caveat, some student canopies are very slow at solving their own line twists, so patiently waiting for a student canopy to solve its own line twists - while flying towards a forest - is a fool's errand.
Far better to spread your risers and start kicking out of line twists as soon as you recognize line twists.
