IM. (See INNER MARKER.)IMC. (See INSTRUMENT METEOROLOGICAL CONDITIONS.)IMMEDIATELY.Used by ATC or pilots when such action compliance is required to avoid an imminent situation. INCERFA (Uncertainty Phase) [ICAO]. A situation wherein uncertainty exists as to the safety of an aircraft and its occupants. INCREASE SPEED TO (SPEED). (See SPEED ADJUSTMENT.)INERTIAL NAVIGATION SYSTEM. An RNAV system which is a form of self-contained navigation. (See Area Navigation/RNAV.)INFLIGHT REFUELING. (See AERIAL REFUELING.)INFLIGHT WEATHER ADVISORY. (See WEATHER ADVISORY.)INFORMATION REQUEST. A request originated by an FSS for information concerning an overdue VFR aircraft. PCG I.2 INITIAL APPROACH FIX. The fixes depicted on instrument approach procedure charts that identify the beginning of the initial approach segment(s). (See FIX.)(See SEGMENTS OF AN INSTRUMENT APPROACH PROCEDURE.)INITIAL APPROACH SEGMENT. (See SEGMENTS OF AN INSTRUMENT APPROACH PROCEDURE.)INITIAL APPROACH SEGMENT [ICAO]. That segment of an instrument approach procedure between the initial approach fix and the intermediate approach fix or, where applicable, the final approach fix or point. INLAND NAVIGATION FACILITY. A navigation aid on a North American Route at which the common route and/or the noncommon route begins or ends. INNER MARKER. A marker beacon used with an ILS (CAT II) precision approach located between the middle marker and the end of the ILS runway, transmitting a radiation pattern keyed at six dots per second and indicating to the pilot, both aurally and visually, that he/she is at the designated decision height (DH), normally 100 feet above the touchdown zone elevation, on the ILS CAT II approach. It also marks progress during a CAT III approach. (See INSTRUMENT LANDING SYSTEM.)(Refer to AIM.)INNER MARKER BEACON. (See INNER MARKER.)INREQ. (See INFORMATION REQUEST.)INS. (See INERTIAL NAVIGATION SYSTEM.)INSTRUMENT APPROACH. (See INSTRUMENT APPROACH PROCEDURE.)INSTRUMENT APPROACH PROCEDURE. A series of predetermined maneuvers for the orderly transfer of an aircraft under instrument flight conditions from the beginning of the initial approach to a landing or to a point from which a landing may Pilot/Controller Glossary be made visually. It is prescribed and approved for a specific airport by competent authority. (See SEGMENTS OF AN INSTRUMENT APPROACH PROCEDURE.)(Refer to 14 CFR Part 91.)(Refer to AIM.)a.U.S. civil standard instrument approach procedures are approved by the FAA as prescribed under 14 CFR Part 97 and are available for public use. b.U.S. military standard instrument approach procedures are approved and published by the Department of Defense. c.Special instrument approach procedures are approved by the FAA for individual operators but are not published in 14 CFR Part 97 for public use. (See ICAO term INSTRUMENT APPROACH PROCEDURE.)INSTRUMENT APPROACH PROCEDURE [ICAO]. A series of predetermined maneuvers by reference to flight instruments with specified protection from obstacles from the initial approach fix, or where applicable, from the beginning of a defined arrival route to a point from which a landing can be completed and thereafter, if a landing is not completed, to a position at which holding or en route obstacle clearance criteria apply. INSTRUMENT APPROACH PROCEDURES CHARTS. (See AERONAUTICAL CHART.)INSTRUMENT DEPARTURE PROCEDURE (DP). A preplanned instrument flight rule (IFR) departure procedure published for pilot use, in graphic or textual format, that provides obstruction clearance from the terminal area to the appropriate en route structure. There are two types of DP, Obstacle Departure Procedure (ODP), printed either textually or graphically, and, Standard Instrument Departure (SID), which is always printed graphically. (See IFR TAKEOFF MINIMUMS AND DEPARTURE PROCEDURES.) (See OBSTACLE DEPARTURE PROCEDURES.) (See STANDARD INSTRUMENT DEPARTURES.) (Refer to AIM.)INSTRUMENT DEPARTURE PROCEDURE (DP) CHARTS. (See AERONAUTICAL CHART.)PCG I.3 INSTRUMENT FLIGHT RULES. Rules governing the procedures for conducting instrument flight. Also a term used by pilots and controllers to indicate type of flight plan. (See INSTRUMENT METEOROLOGICAL CONDITIONS.)(See VISUAL FLIGHT RULES.)(See VISUAL METEOROLOGICAL CONDITIONS.)(See ICAO term INSTRUMENT FLIGHT RULES.)(Refer to AIM.)INSTRUMENT FLIGHT RULES [ICAO]. A set of rules governing the conduct of flight under instrument meteorological conditions. INSTRUMENT LANDING SYSTEM. A precision instrument approach system which normally consists of the following electronic components and visual aids: a. Localizer. (See LOCALIZER.)b. Glideslope. (See GLIDESLOPE.)c. Outer Marker. (See OUTER MARKER.)d. Middle Marker. (See MIDDLE MARKER.)e. Approach Lights. (See AIRPORT LIGHTING.)(Refer to 14 CFR Part 91.)(Refer to AIM.)INSTRUMENT METEOROLOGICAL CONDI-TIONS. Meteorological conditions expressed in terms of visibility, distance from cloud, and ceiling less than the minima specified for visual meteorolog-ical conditions. (See INSTRUMENT FLIGHT RULES.)(See VISUAL FLIGHT RULES.)(See VISUAL METEOROLOGICAL CONDITIONS.)INSTRUMENT RUNWAY. A runway equipped with electronic and visual navigation aids for which a precision or nonprecision approach procedure having straight-in landing minimums has been approved. (See ICAO term INSTRUMENT RUNWAY.)INSTRUMENT RUNWAY [ICAO]. One of the following types of runways intended for the operation of aircraft using instrument approach procedures: |
