Radar Interference Ruled at Potential Wind Farm: Another Red Flag for Cape Wind

Barnstable, Nantucket and Martha's Vineyard Airports surround the Nantucket Sound and the proposed 130 426 foot tall Cape Wind project turbines in the 24 square mile Horseshoe Shoals area.

Yesterday at a site nearly identical to the proposed Cape Wind project FAA ruled a radar interference issue with the Anchorage International Airport.

The FAA made the determination for Cape Wind 4 years ago., before the UK Arms Warfare reports. Please see windstop.org for documents and additional information.

Also, the FAA turned down the 4 town of Yarmouth Wind Turbines about a year ago based on obstruction and electromagnetic interference.The DOD study continues and the FAA will have to take another look at the issues raised by the 3 airports and the air traffic controllers who cite:

400,000 flights a year in the middle of three airports commuter flights (see picture above of proximity of airports to the Nantucket Sound and proposed Cape Wind project) that constantly fly at about 500 to 800 feet during low cloud cover. Keep in mind that the proposed 130 Cape Wind turbines reach a height of 426 feet.

Additionally, the UK CAA will not allow any wind farms within 15 miles per new policy.

"Radar experts recently found electromagnetic waves from the proposed 33-windmill project would be interfere with the airport`s air traffic control radar, as well as other radio-based navigation aids, The Anchorage Daily News reported. Also, the size of the windmills would cause additional problems."


Airport radar tilts with Fire Island windmills FIRE ISLAND:
Electric generation could interfere with airport system.
By MATT WHITE Anchorage Daily News August 21, 2006



"A Chugach Electric idea to put giant, electricity-producing windmills on Fire Island is giving its neighbor, Ted Stevens Anchorage International Airport, a case of bad vibes. "


"Radar experts recently found that electromagnetic waves from the proposed 33-windmill project would be so strong they would warp the signal of the airport's main air traffic control radar. On top of that, the sheer size of the windmills, whose blade tips could reach 400 feet in the air, would also physically block the signal of another key radar already on Fire Island.
Those conclusions come from radar engineers hired by the Federal Aviation Administration to examine what effects Chugach's proposed wind farm would have on the airport. The FAA runs the nation's air traffic systems, including radars and control towers at airports. "


"Anchorage-based Chugach is the state's largest power utility, with customers from Homer to Fairbanks. It has toyed with using wind power for years as a way to bring less-polluting, non-fuel-using electricity generation to the state's Railbelt region. It has studied costs, demand and the best locations for windmills.


"About a thousand VOR radars are spread across North America as navigational beacons. Virtually all planes flying near Anchorage use the Fire Island VOR, from private Cessnas landing at Merrill Field to Elmendorf's fighters to airliners passing five miles overhead. VOR radars need clear lines of sight in all directions, down to a specific angle from the ground.


"Phil Steyer, a Chugach manager closely involved with the project, said that to accommodate the VOR, "we've done some turbine reallocations, some went away and some added with height limitations."


Chugach is partners in the wind-power initiative with three other utilities: Anchorage's Municipal Light & Power, Homer Electric Association and Golden Valley Electric Association in Fairbanks. "


"As a modern windmill spins in a breeze, its blades turn an electric turbine, which uses an electromagnetic field to create electricity. That field, if large enough, can radiate for miles and disrupt radio transmissions of all kinds. "


"According to the FAA's engineers, even Chugach's smaller windmills could produce electromagnetic fields that cause "false target presentations and permanent echoes on air traffic control radar displays.


"In other words, controllers in the airport's control tower might see planes where there were none or be blind to real ones. "

I haven't heards such uninformed sensationalist rubbish in a long while. Check your facts.

In fact, think about it. Any reports of disrupted radio signals next to other power generating stations? The generators in most other power stations are far larger than anything you're going to be able to perch on the top of a wind farm pylon. Yet no reports of disruption arounf ground based stations.

Interesting that other commenters ignore the bird-kill issue and dwell on radio disruptions.

There is a ton of dishonesty and propaganda associated with wind power. It's the white elephant on the landscape, blindly pushed by people who seem to care about everything BUT nature.
