Runway Class Airspace Seymour Johnson AFB Class D Airspace encompasses an area within a 5‐mile radius of the center of the airfield that extends upward to 2,600 feet mean sea level ( MSL ). Use of Class D airspace requires the use of two‐way communication with Air Traffic Control , which must be established prior to entering Class D airspace . No transponder is required . Visual Flight Rules ( VFR ) flights in Class D airspace must have three miles of visibility , and fly an altitude at least 500 feet below , 1,000 feet above , and 2,000 feet laterally from clouds . There are two areas of controlled Class E airspace to the north and south of the airfield . Two circles of Class E airspace extend from the Class D airspace from an elevation of floor to a ceiling of 18,000 feet MSL . The airspace surrounding the Seymour Johnson AFB airfield is depicted on Figure 3‐4 .
Approach and Departure Flight Tracks Flight tracks are influenced by various factors including , avoidance of densely populated areas , efforts to keep noise levels low , and coordination with the FAA . Figure 3‐5 illustrates the primary flight departure tracks and Figure 3‐6 illustrates the primary flight arrival tracks used by Seymour Johnson AFB aircraft . The prevailing winds and the mission are the predominant factors that influence which of the many tracks possible are the ones most commonly observed .
The closed pattern flight tracks are isolated to areas surrounding the installation and consist of low‐level altitude flights . As shown on Figure 3‐7 , the closed pattern flight tracks tend to stay to the south of the installation , away from heavily populated areas , including Base housing and the City of Goldsboro . The operation performed by the aircraft using these flight tracks can potentially create noise and vibration impacts on land uses under these paths .
nonparticipating aircraft ( civilian or military ) to t these activities . Entering SUA without authoriza agency may be extremely hazardous to the aircr various SUA types , Military Operating Areas ( MO the Seymour Johnson AFB Study Area .
Military Operations Area An MOA is airspace designated to separate or se hazardous military activities from Instrument Flig identify for Visual Flight Rules traffic where milit MOAs consist of airspace of defined vertical and the purpose of separating certain military trainin Examples of activities conducted in MOAs includ
• Air combat tactics
• Air intercepts
• Low‐altitude tactics
Additionally , the DOD has been issued an author indicated airspeeds in excess of 250 knots below within active MOAs .
There is one MOA owned and managed by Seym Seymour Johnson AFB JLUS Study Area . The Sey MOA is located west of the installation and inclu Goldsboro and Wayne County . Seymour Johnso Snowbird MOA and Gamecock A MOA located a southwest of Seymour Johnson AFB and in weste Tennessee border , respectively . The parameters provided in Table 3‐3 and illustrated on Figure 3
Special Use Airspace Special Use Airspace ( SUA ) is airspace where military activity or unusual flight conditions may occur . The designation of SUA serves to alert a
