Plans for a wind farm have been rejected after airport bosses said the turbines might disrupt radar systems.
National Wind Power wants to build eight wind turbines
National Wind Power wants to build eight wind turbines at Knabs Ridge on the A59 near Harrogate, North Yorks.
But Leeds Bradford Airport director of operations Andrew Judge raised concerns about the potential impact of the development on air traffic safety.
Harrogate Council district development committee has now voted unanimously to refuse permission for the turbines.
National Wind Power's application will now have to be decided by the Environment Secretary after a public inquiry .
In June, the company said: "If a safety problem is proved then clearly we wouldn't build the wind farm."
Regional development manager for National Wind Power Clare Wilson said studies showed there would be no problem with the radar systems but the company would continue talks with Leeds Bradford Airport.
"We would not build anything which would compromise aircraft safety," she added.
Councillors also rejected the wind farm, which would stand just outside the Nidderdale Area of Outstanding Natural Beauty, on the basis of its impact on the landscape and possible threat to archaeology.
