Overflight – Aircraft that transit a facility's airspace that neither originate nor terminate within that facility's airspace. Point Out – A physical o r automated action taken by a controller to transfer the radar identification of an aircraft to another controller if the aircraft will enter the airspace of another controller and radio communications will not be transferred. Primary Airport – The airpor t with the most volume in the Approach Control's airspace. Proximity Airports – To be counted as a proximity airport, an airport must have at least 300,000 operations per year, and must have one or more additional airports within ten (10) miles (center of airport to center of airport) that also have 300,000 operations or more per year. Runway configuration: Converging runway - Runway configuration that has two (2) or more runways where the magnetic alignment will have crossing flight paths within the air port traffic area (ATA) and where the actual runway surfaces do not overlap. Crossing runway - Runway configuration that has two (2) or more runways where the magnetic alignment will: (1) Have crossing flight paths and where the actual surfaces do overlap , or (2) Have Non - Intersecting Converging Runways whose extended centerlines cross within one mile of the departure ends and where the actual runway surfaces do not overlap. Parallel runways – Two (2) or more runways at the same airport where the magnetic alignment will not have crossing flight paths within the airport traffic area and where the actual runway surfaces do not overlap. Single runway – One (1) runway (either hard surface, grass or sea lane) at airports for aircraft use or parallel runways at an airport where the two outermost runways are no farther than 2,500 feet apart measured centerline to centerline. Secondary airport – An airport not considered the primary airport for an air traffic control facility for which air traffic services are pr ovided by that ATC facility. Special Use Airspace (SUA) – Airspace where activities must be confined or limitations may be imposed on aircraft operations. For the purpose of this standard, the SUA airspace types included are: Alert Area, Controlled Firing Area, Military Operations Area, Prohibited Area, Restricted Area, and Warning Area. Special Visual Flight Rules (SVFR) services /operations – Aircraft operating in accordance with clearances within Class B, C, D, and E surface areas in weather conditions less than the basic VFR weather minimums. Such operations must be requested by the pilot and approved by the controller. Traffic Count Index – A combined measure of the complexity of the air traffic and the sustained traffic index at each facility. It is the measure used to set facility pay levels. For a Metropolitan Tower Complex, the Traffic Count Index for each airport traffic control terminal facility is
