2/19/04Pilot/Controller GlossaryII SAY AGAIN− The message will be repeated.IAF−(See INITIAL APPROACH FIX.)IAP−(See INSTRUMENT APPROACHPROCEDURE.)IAWP− Initial Approach WaypointICAO−(See ICAO Term INTERNATIONAL CIVILAVIATION ORGANIZATION.)ICING− The accumulation of airframe ice.Types of icing are:a. Rime Ice− Rough, milky, opaque ice formed bythe instantaneous freezing of small supercooledwater droplets.b. Clear Ice− A glossy, clear, or translucent iceformed by the relatively slow freezing or largesupercooled water droplets.c. Mixed− A mixture of clear ice and rime ice.Intensity of icing:a. Trace− Ice becomes perceptible. Rate of accumulationis slightly greater than the rate of sublimation.Deicing/anti-icing equipment is not utilizedunless encountered for an extended period of time(over 1 hour).b. Light− The rate of accumulation may create aproblem if flight is prolonged in this environment(over 1 hour). Occasional use of deicing/anti-icingequipment removes/prevents accumulation. It doesnot present a problem if the deicing/anti-icingequipment is used.c. Moderate− The rate of accumulation is such thateven short encounters become potentially hazardousand use of deicing/anti-icing equipment or flightdiversion is necessary.d. Severe− The rate of accumulation is such thatdeicing/anti-icing equipment fails to reduce or controlthe hazard. Immediate flight diversion is necessary.IDENT− A request for a pilot to activate the aircrafttransponder identification feature. This will help thecontroller to confirm an aircraft identity or to identifyan aircraft.(Refer to AIM.)IDENT FEATURE− The special feature in the AirTraffic Control Radar Beacon System (ATCRBS)equipment. It is used to immediately distinguish onedisplayed beacon target from other beacon targets.(See IDENT.)IF−(See INTERMEDIATE FIX.)IFIM−(See INTERNATIONAL FLIGHT INFORMATIONMANUAL.)IF NO TRANSMISSION RECEIVED FOR(TIME)− Used by ATC in radar approaches to prefixprocedures which should be followed by the pilot inevent of lost communications.(See LOST COMMUNICATIONS.)IFR−(See INSTRUMENT FLIGHT RULES.)IFR AIRCRAFT− An aircraft conducting flight inaccordance with instrument flight rules.IFR CONDITIONS− Weather conditions below theminimum for flight under visual flight rules.(See INSTRUMENT METEOROLOGICALCONDITIONS.)IFR DEPARTURE PROCEDURE−(See IFR TAKEOFF MINIMUMS ANDDEPARTURE PROCEDURES.)(Refer to AIM.)IFR FLIGHT−(See IFR AIRCRAFT.)IFR LANDING MINIMUMS−(See LANDING MINIMUMS.)IFR MILITARY TRAINING ROUTES (IR)− Routesused by the Department of Defense and associatedReserve and Air Guard units for the purpose ofconducting low-altitude navigation and tactical trainingin both IFR and VFR weather conditions below10,000 feet MSL at airspeeds in excess of 250 knotsIAS.IFR TAKEOFF MINIMUMS AND DEPARTUREPROCEDURES− Title 14 Code of FederalPCG I−1
