A new configuration for the Class B airspace centered on the Dallas/Fort Worth International Airport in Texas takes effect March 6.
AOPA is urging pilots to become thoroughly familiar with the new design, which lowers the Class B floor in several sectors, redraws the northern boundary, and excludes a small section of airspace in the southwest portion of the Class B surface area.
"Pilots should become thoroughly familiar with the changes, and plan accordingly," said Melissa McCaffrey, AOPA senior government analyst for air traffic services.
The March 6 effective date of the modifications will allow the new airspace configuration to coincide with new editions of the Dallas/Fort Worth Terminal Area and Sectional charts.
The association expects the FAA to follow up the redesign with a related action to resolve ambiguity in an easterly section, where the Addison Airport’s existing Class D airspace is designated below 3,000 feet; under the new design, the Class B airspace floor above the airport will be 2,500 feet as of March 6.
The FAA is expected to modify the Class D airspace at Addison to conform to the new Class B airspace layout, McCaffrey said.
