FAAs ATL Class B Airspace ProposalPrepared by Mike Van Wie For the Dunwoody City Council February 22, 2010

What is Class B Airspace? Surrounds the nation'sbusiest airports Surface to 10,000 feet MSL; circular diameter of 40 nautical miles Pilots must obtain a clearance from ATC before entering Class B airspace; maintain radio contact with ATC Aircraft must be equipped with an altitude-encoding transponder

ComparisonChange This To This

East Operation December 11, 2009 0600 - 1200

West Operation December 9, 2009 0600 - 1200

Things to Consider If these proposed changes are toaccommodate the addition of the 5th runway at ATL Airport, why are such significant changes being made to the northern airspace?

West Operation December 9, 2009 0600 - 1200

East Operation December 11, 2009 0600 - 1200

What does this mean? Previously unpopulated airspace above PDK nowpopulated Visual Flight Rules aircraft Aircraft compressed into less airspace Same number of aircraft operating in less airspace

Instrument Flight Rules aircraft On the ground delays for departing Instrument Flight Rules aircraft Lower initial altitude for departing flights equals more noise Earlier descent of inbound aircraft equals more noise All factors mean more fuel consumption more emissions

Environmental Process The FAA intends to categorically exclude(CATEX) the proposal from a thorough environmental review FAA reasoning FAA is only changing the airspace to capture aircraft that are Airspace changes at 3,000 ft AGL and above are typically

already thereairspace doesnt make noise, only airplanes do CATEX

This reasoning ignores the environmentalconsequences, both noise and increased emissions, at satellite airports like PDK.

Important Differences Existing12 mile line Altitude directly above PDK 8,000 ft Altitude immediately south of PDK6,000 ft Altitude immediately north of PDK8,000 ft

Proposed15 mile line Altitude directly above PDK 5,000 ft Altitude immediately south of PDK5,000 ft Altitude immediately north of PDK7,000 ft

Bottom Line Reduces the airspace available to all aircraft in and out of PDK
