Properly equipped (RNP 10 and RNP 4) aircraft will be able to take advantage of a new routing structure in the West Atlantic Route System (WATRS) off the east coast of the U.S. starting June 5. In a podcast interview with AVwebBiz, FAA Oceanic Procedures Specialist Scott Luka says the FAA is cutting lateral separation from as much as 90 miles to 50 miles over an expanse of ocean from 200 miles south of Long Island to Puerto Rico and between the continent and Bermuda. That will increase to nine the number of north/south routes available to business aircraft and airliners from the current five. It means will be offer better altitudes to a lot more flights, Luka told AVweb.
