Why are we so reluctant to tie down in the UK? It's extremely rare to find a parking area with proper eye bolts, let alone the tensioned cables with sliding chains the Americans use on dirt parking. Even when you do find a tie down ring it's usually got a bit of washing line string on it as mentioned above. (Nylon rope also deteriorates - I know this through various towing escapades).
My own airfield has had more than one aircraft wrecked in blow away incidents and my own PA-28 was rotated while chocked so low wings can move if the wind is strong enough.
Now I have a 'claw' and use it if the forecast looks bad enough. I doubt if there's any real difference in the max wind possible in UK vs. US (my own garden has been ripped thro' by a tornado) so why the cultural difference in securing aircraft?
