will be outfitted to accomplish repair of that magnitude. FIX PHASE—The portion of a scheduled inspection that involves the correction of discrepancies found during the look phase. FIXED ALLOWANCE MANAGEMENT AND MONITORING SYSTEM—A  mechanized supply data base management system used by most major naval air activities to support the IMA supply operation. FLEET CONTROLLED MATERIAL—Material under the requisitioning, rationing, and issue control of the aviation TYCOMs, COMNAVAIR- LANT/COMNAVAIRPAC, or their designated controlling agencies. FLEET INTRODUCTION PROGRAM—An ac- celerated flight program that lasts approximately 100 flight hours per aircraft. Normally conducted at the NAVAIRWARCENACDIV Patuxent River for the purpose of introducing a new model to fleet personnel for indoctrination in the operation and maintenance of the aircraft. A secondary purpose is to provide a further check on the readiness of the aircraft for fleet delivery. FLYABLE—An aircraft in such material condition as to be safe and capable of normal flight operations without regard to capability to perform a specific mission, weather, personnel availability, base condition, fuel condition, armament, or flight schedule. FMC—Full Mission Capable—Material condition of an aircraft that can perform all of its missions. FMC is subdivided into FMC Maintenance (M) and FMC Supply (S). FMC Hours = MC Hours - (PMC Hours + OPC Hours). FMCM—Full Mission Capable Maintenance—The material condition of an FMC aircraft that is not OPC because of maintenance requirements existing on inoperable subsystem(s) which degrade the end item from OPC to FMCM. FMCM time starts when the condition is discovered, except when the discovery is made in flight. In flight malfunction FMCM time starts at the termination of flight. FMCM time stops when maintenance is completed or interrupted by a supply shortage. Work stoppage resulting from parts nonavailability is reported as FMCS. FMCM time resumes when required supply item(s) are delivered to the maintenance activity. FMCM Hours = FMC Hours - FMCS Hours. FMCS—Full Mission Capable Supply—The material condition of an FMC aircraft not OPC because maintenance required to correct the discrepancy which degrades the end item from OPC to FMCM cannot continue because of a supply shortage. FMCS time starts when a supply demand has been made for an item required to continue maintenance. FMCS time stops at the time the material is delivered to the designated delivery point or change of EOC Code. FMCS Hours = FMC Hours - FMCM Hours. FOD—Foreign Object Damage—Damage to aero- nautical equipment (for example, aircraft, engines, missiles, drones, SE) caused by an object(s) external to the equipment. (Gas turbine engine FOD is defined as damage that exceeds serviceable limits caused by ingestion of objects not organic to the damaged engine.) FPT—First Pilot Time. FREDS—Flight Readiness Evaluation Data System. FS—Fleet Support. FUNCTIONAL TEST—The testing of installed aircraft/engines, accessories, and equipage to determine proper functioning, particularly with respect to the applicable system. GAS TURBINE ENGINES—All turbine engines, whether used to power flight (including target drones, missiles, and missile targets), for auxiliary power, or for starting purposes. Airborne or ground units are included in the meaning of this term. GENADMIN —General Administration (message). GFE—Government Furnished Equipment—Equip- ment that has been selected and is to be furnished by the government to a contractor or government activity for installation in, use with, or in support of the aeronautical system. during production, conversion, or modification. GTE—Gas Turbine Engine. HMR—Hazardous Material Report. HOT REFUELING—An operational evolution where an aircraft is refueled while the engine(s) is (are) operating. HOT SEATING—An operational evolution where the pilot/crew of an aircraft is changed while the AI-10
