Satellite-guided flight paths will cut Logan Airport noise, officials say

A proposed satellite-guided flight route for planes departing one of Logan International Airport’s major runways would send planes along more precise routes and reduce airplane noise in some urban areas, officials say.

The plan is to enable flights out of Logan to use area navigation, or RNAV, which uses satellite systems to keep planes within a milewide route, rather than the traditional method of visual navigation. By 2015, more than 80 percent of the fleet at Logan will be equipped to use RNAV, according to the Federal Aviation Administration.
