a.Nonprecision Approach Runway.An instru-ment runway served by visual aids and a nonvisual aid providing at least directional guidance adequate for a straight-in approach. b.Precision Approach Runway, Category I.An instrument runway served by ILS and visual aids intended for operations down to 60 m (200 feet) decision height and down to an RVR of the order of 800 m. c.Precision Approach Runway, Category II.An instrument runway served by ILS and visual aids intended for operations down to 30 m (100 feet) decision height and down to an RVR of the order of 400 m. d.Precision Approach Runway, Category III.An instrument runway served by ILS to and along the surface of the runway and: 1.Intended for operations down to an RVR of the order of 200 m (no decision height being applicable) using visual aids during the final phase of landing; 2.Intended for operations down to an RVR of the order of 50 m (no decision height being applicable) using visual aids for taxiing; 3.Intended for operations without reliance on visual 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 be matched to the scale of nonvisual aids provided. The criterion for the selection of visual aids is the conditions in which operations are intended to be conducted. INTEGRITY. The ability of a system to provide timely warnings to users when the system should not be used for navigation. INTERMEDIATE APPROACH SEGMENT. (See SEGMENTS OF AN INSTRUMENT APPROACH PROCEDURE.)INTERMEDIATE APPROACH SEGMENT [ICAO]. That segment of an instrument approach procedure between either the intermediate approach fix and the final approach fix or point, or between the end of a reversal, race track or dead reckoning track PCG I.4 procedure and the final approach fix or point, as appropriate. INTERMEDIATE FIX. The fix that identifies the beginning of the intermediate approach segment of an instrument approach procedure. The fix is not normally identified on the instrument approach chart as an intermediate fix (IF). (See SEGMENTS OF AN INSTRUMENT APPROACH PROCEDURE.)INTERMEDIATE LANDING. On the rare occasion that this option is requested, it should be approved. The departure center, however, must advise the ATCSCC so that the appropriate delay is carried over and assigned at the intermediate airport. An intermediate landing airport within the arrival center will not be accepted without coordination with and the approval of the ATCSCC. INTERNATIONAL AIRPORT. Relating to interna-tional flight, it means: a.An airport of entry which has been designated by the Secretary of Treasury or Commissioner of Customs as an international airport for customs service. b.A landing rights airport at which specific permission to land must be obtained from customs authorities in advance of contemplated use. c.Airports designated under the Convention on International Civil Aviation as an airport for use by international commercial air transport and/or interna-tional general aviation. (See ICAO term INTERNATIONAL AIRPORT.)(Refer to AIRPORT/FACILITY DIRECTORY.)(Refer to IFIM.)INTERNATIONAL AIRPORT [ICAO]. Any airport designated by the Contracting State in whose territory it is situated as an airport of entry and departure for international air traffic, where the formalities incident to customs, immigration, public health, animal and plant quarantine and similar procedures are carried out. INTERNATIONAL CIVIL AVIATION ORGA-NIZATION [ICAO]. A specialized agency of the United Nations whose objective is to develop the principles and techniques of international air Pilot/Controller Glossary navigation and to foster planning and development of international civil air transport. a. Regions include: 1.African-Indian Ocean Region 2.Caribbean Region 3.European Region 4.Middle East/Asia Region 5.North American Region 6.North Atlantic Region 7.Pacific Region 8.South American Region INTERNATIONAL FLIGHT INFORMATION MANUAL. A publication designed primarily as a pilot’s preflight planning guide for flights into foreign airspace and for flights returning to the U.S. from foreign locations. INTERROGATOR. The ground-based surveillance radar beacon transmitter-receiver, which normally scans in synchronism with a primary radar, transmitting discrete radio signals which repetitious-ly request all transponders on the mode being used to reply. The replies received are mixed with the primary radar returns and displayed on the same plan position indicator (radar scope). Also, applied to the airborne element of the TACAN/DME system. (See TRANSPONDER.)(Refer to AIM.)INTERSECTING RUNWAYS. Two or more runways which cross or meet within their lengths. (See INTERSECTION.)INTERSECTION. a.A point defined by any combination of courses, radials, or bearings of two or more navigational aids. b.Used to describe the point where two runways, a runway and a taxiway, or two taxiways cross or meet. INTERSECTION DEPARTURE. A departure from any runway intersection except the end of the runway. (See INTERSECTION.)INTERSECTION TAKEOFF. (See INTERSECTION DEPARTURE.)IR. (See IFR MILITARY TRAINING ROUTES.)PCG I.5 J JAMMING. Electronic or mechanical interference which may disrupt the display of aircraft on radar or the transmission/reception of radio communications/ navigation. JET BLAST. Jet engine exhaust (thrust stream turbulence). (See WAKE TURBULENCE.)JET ROUTE. A route designed to serve aircraft operations from 18,000 feet MSL up to and including flight level 450. The routes are referred to as “J” routes with numbering to identify the designated route; e.g., J105. |
