2016 CBA Tentati ve Agreement Page 175 of 217 Foreign Country – In order to receive credit for interacting with a fore ign country, facilities with adjacent airspace must routinely coordinate and transfer air traffic with an air traffic facility from another sovereign nation. Large Hub Airport – For the purpose of this standard, a terminal air traffic control facility wi th an annual air traffic count of 300,000 or more. LAWRS – A limited aviation weather reporting station is a facility where observations are taken, prepared and transmitted by certified FAA air traffic control specialists on a limited basis. At these fac ilities, various degrees of automated sensors and/or other automated equipment may be available. However, when on duty, the LAWRS observer has the complete responsibility for the surface aviation weather elements. Instrument flight rules (IFR) – Rules tha t govern the procedures for conducting instrument flight. Major Metropolitan Area – A metropolitan statistical area as defined by the U.S. Census Bureau containing a single core with a population of 2.5 million or more. Metropolitan Tower Complex – Two (2) or more airport traffic control terminals that provide traffic advisories, spacing, sequencing, and separation services to VFR and IFR aircraft operating in Class B airspace within the vicinity of the airport using a combination of radar and direct obs ervations. These airport traffic control terminals must serve separate Large Hub Airports located in a major metropolitan area and independently be within one (1) facility pay level of each other. Additionally, each airport must be located within fifteen (15) nautical miles, (center of airport to center of airport) and have traffic flows that have to be closely coordinated between facilities such that the operational configuration of one (1) airport affects the operational configuration of the other(s). Mix of traffic – Currently the Standard considers the mix of air traffic for terminals and CCFs to be comprised of three categories of traffic: (1) air carrier and military combined, (2) general aviation (including non - military helicopters), and (3) air ta xi. When the Agency's automated data collection capability at these facilities is able to identify jet, turbo prop, and piston traffic separately, it is contemplated that their traffic mix factor will be revised to be consistent with the center measure of traffic mix. MOA – Military Operations Area Non - Radar Sector (in Approach Control) – An exclusive non - radar sector (i.e. area) in what is otherwise classified as an Approach Control or an Approach Control portion of an up/down facility. When controllers are assigned to this sector they are responsible for the control and separation of air traffic without physical or mechanical visual reference to the aircraft under the controllers' jurisdiction. Without radar, the controllers use flight progress strips to document aircraft movement and to develop a picture in their minds of all the aircraft using the airspace. Separation standards between the aircraft are specified in terms of time and/or mileage and they vary according to the speed of the aircraft and the navigational equipment available to the pilot. Oceanic Traffic – Only air traffic traversing airspace over the oceans of the world and the Gulf of Mexico, are to be counted if both of the following conditions are met: (1) no direct communications between aircraft and controller, and (2) ICAO non - radar procedures are used
