Pilot/Controller Glossary 8/5/04INSTRUMENT LANDING SYSTEM− A precisioninstrument approach system which normally consistsof the following electronic components and visualaids: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 interms of visibility, distance from cloud, and ceilingless than the minima specified for visual meteorologicalconditions.(See INSTRUMENT FLIGHT RULES.)(See VISUAL FLIGHT RULES.)(See VISUAL METEOROLOGICALCONDITIONS.)INSTRUMENT RUNWAY− A runway equippedwith electronic and visual navigation aids for whicha precision or nonprecision approach procedurehaving straight-in landing minimums has beenapproved.(See ICAO term INSTRUMENT RUNWAY.)INSTRUMENT RUNWAY [ICAO]− One of thefollowing types of runways intended for the operationof aircraft using instrument approach procedures:a. Nonprecision Approach Runway−An instrumentrunway served by visual aids and a nonvisualaid providing at least directional guidance adequatefor a straight-in approach.b. Precision Approach Runway, Category I−Aninstrument runway served by ILS and visual aidsintended for operations down to 60 m (200 feet)decision height and down to an RVR of the order of800 m.c. Precision Approach Runway, Category II−Aninstrument runway served by ILS and visual aidsintended for operations down to 30 m (100 feet)decision height and down to an RVR of the order of400 m.d. Precision Approach Runway, Category III−Aninstrument runway served by ILS to and along thesurface of the runway and:1. Intended for operations down to an RVR ofthe order of 200 m (no decision height beingapplicable) using visual aids during the final phase oflanding;2. Intended for operations down to an RVR ofthe order of 50 m (no decision height beingapplicable) using visual aids for taxiing;3. Intended for operations without reliance onvisual reference for landing or taxiing.Note 1: See Annex 10 Volume I, Part I, Chapter 3,for related ILS specifications.Note 2: Visual aids need not necessarily bematched to the scale of nonvisual aids provided.The criterion for the selection of visual aids is theconditions in which operations are intended to beconducted.INTEGRITY− The ability of a system to providetimely warnings to users when the system should notbe used for navigation.INTERMEDIATE APPROACH SEGMENT−(See SEGMENTS OF AN INSTRUMENTAPPROACH PROCEDURE.)INTERMEDIATE APPROACH SEGMENT[ICAO]− That segment of an instrument approachprocedure between either the intermediate approachfix and the final approach fix or point, or between theend of a reversal, race track or dead reckoning trackprocedure and the final approach fix or point, asappropriate.INTERMEDIATE FIX− The fix that identifies thebeginning of the intermediate approach segment of aninstrument approach procedure. The fix is notnormally identified on the instrument approach chartas an intermediate fix (IF).(See SEGMENTS OF AN INSTRUMENTAPPROACH PROCEDURE.)INTERMEDIATE LANDING− On the rare occasionthat this option is requested, it should be approved.The departure center, however, must advise theATCSCC so that the appropriate delay is carried overand assigned at the intermediate airport.
