"Random Knots..." - see, this is what happens when parents emphasize Soccer over Scouting....no one knows how to tie good knots anymore!
A bowline gives a good solid connection to a hardpoint on the ground, and I am a fan of the taught line hitch (which is a variation on the classic half hitch) coming down the standing part of the rope after looping through the aircraft attachment point.

As my father-in-law says...."Don't know a knot? Tie a lot." He was a very active cave diver so he knows plenty of knots. I've enjoyed learning some of them from him.
Actually, as an airport manager, I've seen plenty of different knots to tie down planes. While some wouldn't hold very long in a Kansas thunderstorm, some are just amazing. I've spent more time than I care to admit, out on the ramp, trying to reverse engineer a few of them.

Nice report Paul and Louise.
You should polish them though

carabiners?
I bought these, and spent an hour at REI, and could not find a 'biner that fit, except for a small aluminum one.
I am worried that the little aluminum carabiners, which are made for clipping gear to your harness, not for clipping yourself to a rope, are not strong enough for tie-downs.
So, for now, these pretty tie-downs are sitting in my tool box.
Also, the holes in the tiedown "ring" remove so much metal that the tiedown itself is not as strong as I think it should be. The web site says they yield at 1500 lbs. That's probably good enough.
If I could find some small stainless steel carabiners that fit, I guess I would try them again.

Here's a photo of one that I made a few years ago (they're painted now):
Good for a half-knot or so over the round rings if you plug the hole when flying!

You'll need those 'biners, though. The sharp edges will reduce rope strength if you tie them directly.

There is an alternative to the caribiner. From my local Lowes':

Yes, that is a very good solution, I use shackles like that on the halyards on my sailboat. But it is a bit fussy to have to put those on first, then tie the rope through it. 'Biners are so quick - just wish they made one small enough that was strong enough.
They do make shackles with a spring-loaded 1/4-turn latching pin, but they also are not strong enough.

Just remember...
If you are leaving the tie-down rings in the plane, depending on what they are made of they may react with the aluminum bracket they are screwed into.
I have seen one RV-10 that has left the ?stock? tie-down rings in place and the corrosion is evident and the plane isn?t that old.
That is the one reason I always remove my rings.

There's an app for that (Grog Knots). I never can remember knots. Also
The biner was a great idea. Spent some time in REI myself recently.
