Aviation Boatswain's Mates (AB) play a major part in launching and recovering naval aircraft quickly and safely from land or ships.
Air-Traffic Controllers (AC) assist with the speedy flow of air traffic by directing and controlling aircraft. They operate field lighting systems and communicate with aircraft. They furnish pilots with information regarding traffic, navigation and weather conditions, as well as operate and adjust ground-controlled approach (GCA) systems and interpret targets on radar screens and plot aircraft positions.
Aviation Machinist's Mates (AD) are aircraft engine mechanics. They inspect, adjust, test, repair and overhaul aircraft engines and propellers in turbojet, helicopter, or propeller aircraft. ADs also perform routine maintenance, prepare aircraft for flight and assist in handling aircraft on the ground.
Aviation Electrican's Mates (AE) are responsible for aircraft electrical power generating and converting systems. They maintain lighting, control, and indicating systems and can install as well as maintain flight and engine instrument systems.
Airframe/Avionics Master Chiefs (AF/AV) AM, AME, and AD combine at paygrade E-9 to the rating of Master Chief Aircraft Maintenanceman (AFCM).
AE and AT combine at paygrade E-9 to the rating of Master Chief Avionics Technician (AVCM).
Aerographer's Mates (AG) are trained in meteorology and the use of aerological instruments that monitor air pressure, temperature, humidity, wind speed, and direction. They prepare weather maps and forecasts and can analyze atmospheric conditions to determine the best flight levels for aircraft. An AG can measure wind and air density to aid the accuracy of anti-aircraft firing, shore bombardment and delivery of weapons by aircraft.
Aviation Structural Mechanics (AM) maintain all aircraft main and auxiliary hydraulic power systems, actuating subsystems, landing gear, and utility systems throughout the aircraft. Responsible for maintenance on the aircraft fuselage (mainframe) wings airfoils, and associated fixed and moveable surfaces and flight controls. They work on systems such as air conditioning, heating, pressurization and oxygen, and ejection seat systems.
Aviation Ordnancemen (AO) operate and handle aviation ordnance equipment. They are responsible for the maintenance of guns, bombs, torpedoes, rockets, and missiles. Their duties include the stowing, issuing, and loading of munitions and small arms.
Aviation Support Equipment Technicians (AS) operate, maintain, repair and test automotive electrical systems in ground equipment, gasoline and diesel systems, and associated automotive, hydraulic and pneumatic systems. They also maintain gas turbine compressor units, ground air-conditioning units, perform metal fabrication, repair and painting of tow tractors and other aircraft servicing units.
Aviation Electronics Technicians (AT) are responsible for the maintenance of all aircraft radio, radar, and other rapid communications devices. They maintain all navigation and weapons system equipment.
Naval Aircrewman (AW) operate airborne radar and electronic equipment used in detecting, locating, and tracking submarines. They provide information for aircraft and surface navigation and act as helicopter-rescue crewmen, and function as part of the flight crew on long-range and intermediate-range aircraft. In 2009, the AW rating merged with all other Aircrew NEC's and changed their title from Aviation Warfare System Operators to Naval Aircrewman. All five AW ratings merge at the E-9 level to just "AW."
Aviation Maintenance Administrationmen (AZ) perform clerical, administrative, and managerial duties necessary to keep aircraft maintenance activities running smoothly. They schedule and coordinate the maintenance workload, including inspections and modifications to aircraft and equipment.
Aircrew Survival Equipmentmen (PR) are responsible for the packing and care of parachutes. They maintain flight clothing, rubber life rafts, life jackets, oxygen-breathing apparatus, protective clothing, and air-sea rescue equipment.
