Air conditioning and refrigeration mechanics assemble, install, maintain and repair air conditioning and refrigeration systems and equipment. Tasks include - (a) interpreting blueprints, drawings and other specifications; (b) assembling, installing and repairing components such as compressors, motors, condensers, evaporators, switches and gauges for air conditioning and refrigeration systems; (c) connecting piping and equipment by bolting, riveting, welding or brazing; (d) testing systems, diagnosing faults and performing routine maintenance or servicing. Examples of the occupations classified here: - Air conditioning equipment mechanic - Refrigeration mechanic Some related occupations classified elsewhere: - Plumber and pipe fitter - 7126 - Ventilation pipe fitter - 7126.

Air force officers specialise in flying or ground duties, and supervise a team of air force personnel. They coordinate their team's training and welfare, and perform duties specific to their area of specialisation.

Air force pilots operate aircrafts in combat missions, patrol missions, or search and rescue missions. They ensure aircraft maintenance, and communicate with air force bases and other vessels to ensure safety and efficiency in operations.

Air pollution analysts conduct field and lab tests to examine the pollution of air in different areas. They also identify sources of pollution.

Air separation plant operators control and maintain the equipment for nitrogen and oxygen extraction from air, ensuring the required operational parameters of pressure, flow and temperature are met. They perform product purity tests and monitor its transfer to storage tanks or to fill cylinders.

Air traffic controllers assist pilots by providing information concerning the height, speed and course. They assist pilots in order to facilitate a safe take off and landing of aircrafts. They are responsible for maintaining a secure and orderly movement of aircraft along major air routes up in the sky and around airports. They control air traffic in and within vicinity of airports according to established procedures and policies to prevent collisions and to minimise delays arising from traffic congestion.

Air traffic controllers direct aircraft movements in airspace and on the ground, using radio, radar and lighting systems, and provide information relevant to the operation of aircraft. Tasks include - (a) directing and controlling aircraft approaching and leaving airport and their movement on the ground; (b) directing and controlling aircraft operating in designated airspace sectors; (c) examining and approving flight plans; (d) informing flight crew and operations staff about weather conditions, operational facilities, flight plans and air traffic; (e) applying knowledge of principles and practices of air traffic control in order to identify and solve problems arising in the course of their work; (f) initiating and organizing emergency, search and rescue services and procedures; (g) directing activities of all aircraft and service vehicles on or near airport runways; (h) maintaining radio and telephone contact with adjacent control towers, terminal control units and other control centres, and coordinating the movement of aircraft into adjoining areas. Examples of the occupations classified here: - Air traffic controller.

Air traffic instructors train people in all the matters regarding with the operations in air navigation services such as the management of flight traffic and the communication for navigation in aerodromes. They teach all the directives issued by air traffic control for the purpose of passing to trainees the sense of safety and expeditious flow of air traffic.

Air traffic managers coordinate the planning of ground control, the maintenance of the aircrafts, and the handling of customers. They strive for the most efficient use of resources in directing the aircraft. They manage safety, quality, and risks in everyday work. They also plan and compare performance with other air navigation service providers.

Air traffic safety electronics technicians perform technical tasks concerning the design, installation, management, operation, maintenance and repair of air traffic control and air navigation systems. Tasks include - (a) carrying out technical duties related to the development of electronic and computerized air navigation systems and equipment, and testing prototypes; (b) providing technical help in the design and layout of specific interface circuitry of air navigation and aircraft detection tracking systems; (c) preparing and contributing to the preparation of cost estimates and technical and training specifications for air traffic control and safety equipment; (d) providing or assisting with the technical supervision of construction, installation and operation of ground-based air navigation equipment and its maintenance and repair to ensure that standards and specifications are met; (e) applying the knowledge and skills of air traffic safety engineering principles and practices in order to identify and solve problems arising in the course of their work; (f) developing, modifying and debugging system software; (g) modifying existing ground-based air navigation systems and equipment to adapt them to new air traffic control procedures, in order to improve capability, reliability and integrity, or to facilitate air traffic control procedures and airspace designation; (h) controlling, monitoring and certifying communication navigation and surveillance air traffic management equipment, and calibrating the ground-based air navigation system to ensure maximum accuracy and safety of flight, take-off and landing operations; (i) providing technical training and supervising other workers. Example of the occupations classified here: - Air traffic safety engineer - Air traffic safety technician Some related occupations classified elsewhere: - Aeronautical engineer - 2144 - Electronics engineer - 2152 - Aeromechanic - 7232 - Aircraft maintenance engineer (avionics) - 7421 - Avionics technician - 7421.

Air traffic safety technicians provide technical support regarding the safety of air traffic control and navigation systems. They design, maintain, install and operate these systems both in the airport and on board the aeroplane according to regulations.
