Bagheera, you explained the Moving Target Indicator principle quite well and that is the problem with mill blades and primary RADAR in line of sight.

dave1010;

your para C. Primary RADARs don't cross reference with other RADAR heads. The display shows what the head sees (Army!?).

your para D. Had there been a non frangible windmill on Phuket aerodrome, it may well have stopped
OG 269 from veering into the embankment.

I suspect that the MOD are worried about their radar not detecting very low flying aircraft and missiles. Perhaps not a problem in this case because radar dish could be placed the other side of the WM?.

The point is, Wind turbines are a Political Sop and generate little energy and cost a fortune [offset by our Taxpayers subsidy via the Labour Government] and are an eyesore to boot. If ever we needed a sign that the country is losing its marbles then it is the Greens insistence that renewable energies are so much better than Coal, Oil and Nuclear power sources. Modern Coal powered plants would enable energy at the flick of a switch [ for those cold nights that will inevitably come, usually accompanied by still air [so no pathetic wind power output then?] and if history confirms Climate Change as a natural event and not Man Made, then all those squillions of pounds in Carbon Offset/Trading/Claptrap will have been thrown down the proverbial drain - instead of making roads smooth, building new houses, educating our children, cleansing our hospitals etc.
There is no Political Party for those who think "Global Warming" is a con and that we should remember that the Middle Ages rejoiced in much warmer weather than we have now
and no one was driving cars or flying 747's!!!!
CO2 is not a poison - trees/plants die without it.
Final point - removal of 24 hour "Breaking News" would be a huge bonus and would help avoid the scaremongering to which we are now subjected.
Yesterdays "Tornadoes"??? [Squall line] had cameras Zooming in on 6 tiles laying on grass as proof of a 'disaster in the Midlands'
When will the hysterical madness fade away and sense and sensibility return? :rolleyes:

I understand that the EMA wind farm construction is now well under way.

How badly will this affect the locally based air ambulance unit? A little bird tells me their helipad is less than 200 metres downwind (i.e. of the prevailing wind) of the turbines and they aren't happy bunnies. A no-fly zone has apparently been declared (yes, at an airport!) and this will prevent their normal Class A departure path. :confused:

Turbines certainly do produce turbulence. I believe it takes around 10 blade diameters downwind for the freestream windspeed to recover, so the turbulence caused would probably extend a similar distance.
I totally agree. A short time ago we were approaching AMS over Flevoland (to the East of PAM) where each "new" farm appears to have it's own turbine. The whole of Flevoland was covered in dense but shallow fog and we could plainly see the wind turbines poking through the top. What was interesting was that each turbine not only disturbed the air directly downwind but the entire downwind quadrant. The distance affected appeared to be approx. 10 blade diameters. How much the air was disturbed I don't know, but you could clearly see the effect of the turbines on the fog and by implication, the surrounding air.

Right on!

The real scandal is the NIMBYs.
Not the ones you would imagine.

The Dept Energy & Climate Control ministers; Chris Huhne (lives in Hampshire) Charles Hendry & Greg Barker (who live in East Sussex)

The big scandal is the DECC NIMBYs, the three DECC ministers.

We are all told we must get 30% of our electricity from renewable sources - most from on-shore wind.

So Hampshire uses 682MW but 0MW approved from wind
East Sussex - uses 224MW, approved less than 3MW

But compare that with others:
Northumberland - uses 172MW - approved 272MW of wind
East Yorks - uses 184MW - approved 108MW
Cornwall - uses 307, approved 156
Cumbria - uses 315, approved 133
Lancashire - uses 589, approved 136
Lincolnshire - uses 395, approved 84
Northamptonshire - uses 386, approved 83
Cambs - uses 367, approved 153
Durham - uses 231, approved 147

And these counties have much more in the pipeline - nothing where DECC ministers are living!

Using their own statistics

Clearly the message is NIMBY - or Not In My County!
But they'll force them in everywhere else and accuse others of harming children's futures.
So much for Climate Change responsibility.
