ADP—Automated Data Processing. AE—Aviation Electrician’s Mate. AEMS—Aircraft Engine Management System-An automated engine management system that provides on-line status and condition of any engine, propulsion system, or module. The system is used extensively by ACCs and other managers to effect efficient distribution of engine assets. AEPS—Aircrew Escape Propulsion System. AERONAUTICAL ALLOWANCE LISTS—Lists of equipment and material determined from known or estimated requirements as necessary to place and maintain aeronautical activities in a material readiness condition. In the case of aerological and photographic material, the requirement is extended to all applicable naval activities. AERONAUTICAL EQUIPMENT—The equipment used within the maintenance complex that contributes to the completion of the maintenance mission. It includes aircraft, SE, aviators’ equipment, and other similar devices. AERONAUTICAL MATERIAL—All the material used in the operation and maintenance of aircraft. AESR—Aeronautical Equipment Service Record— An insert to the basic aircraft logbook used as a service record for various aircraft equipment, such as power plants and propellers. AGE—The process of accumulating operating service months. AIMD—Aircraft Intermediate Maintenance Depart- ment—The department of an aviation ship or NAS responsible for the check, test, repair, or manufacture of aeronautical components and SE for the supported aircraft. AIR—Aircraft Inventory Record. AIRS—Aircraft Inventory Reporting System. AIRCRAFT—An air vehicle, designed primarily for flight in the atmosphere, that has incorporated in its prime design the ability/requirement for human occupancy. AIRCRAFT AIRFRAME—The structural compo- nents, including the framework and skin of such parts as the fuselage, empennage, wings, landing gear (minus tires), and engine mounts. AIRCRAFT EQUIPMENT CONFIGURATION LIST—A listing of the avionics components installed in aircraft, cross-referenced to applicable ARRs, that contain the support requirements for outfitting purposes. AIRCRAFT LOGBOOK—A detailed service record maintained for each individual aircraft. AIRFRAME ACCESSORIES—The items of equipment required for operation of the aircraft and not considered an integral part of the airframe or engine, such as wheels, brakes, hydraulic equipment, fuel systems, deicing equipment, anti-icing equipment, and other items regardless of whether attached to the engine or airframe. AIRWORTHINESS INSPECTION—Applicable to commercial-off-the-shelf aircraft and provides for a periodic standard D-level rework normally performed per the manufacturer’s FAA-approved maintenance requirements. This rework includes a comprehensive inspection together with critical defect corrosion correction and compliance with outstanding FAA airworthiness directives and approved manufacturer’s service bulletins. AIS—Automated Information System. ALCOM—All Commands (Message). ALMILACT—All Military Activities (Message). ALSS—Aviation Life Support System—Items of equipment and clothing needed to allow aircrew members and aircraft passengers to function within all parameters of the flight environment., safely egress from disabled aircraft and descend to the surface, survive on land and water, and interface with rescue forces. AM—Aviation Structural Mechanic or Amendment. AMCM—Airborne Mine Countermeasures—Aircraft weapons systems used to detect and neutralize sea mines. AMMRL PROGRAM—Aircraft Maintenance Material Readiness List Program—Provides data required for effective management of selected SE at all levels of aircraft maintenance. Within this program, SERMIS and IMRL are significant. AMO—Assistant Maintenance Officer. AMPN —Amplification (Message). AMRR—Aircraft Material Readiness Reporting. AMSU—Aeronautical Material Screening Unit. AO—Aviation Ordnanceman. AI-2
