airplane tie-down knots

[knot4u]

What a lot of ‘tripe’ - It is obvious that roo or knot4u have ever tied a light aircraft down or even know what a tiedown is!
The rope used is already secured to a heavy weight or ground spike (if not it is secured to a ground line with a round turn and two half hitches or similar hitch) - the wing end is adequately secured to a ring built into the underside of the wing using a round turn and two half hitches (slipped if you like) NO purchase is required just make sure there is no slack between the two fixings.

Weird, I’ve watched about 20 videos on airplane tie-down knots. Nobody uses a Roundturn & Two Half Hitches. For one thing, it looks like the rope is often too thick to go twice through the ring on the airplane. You should make a video to school everybody, including this guy…
