GLOSSARY APPENDIX A provides en route aerial navigation and selected types of nonprecision instrument approaches. Eventual application of GPS as the principal system of navigational guidance throughout the world is anticipated. HELIPAD : A small, designated area, usually with a prepared surface, on a heliport, airport, landing/takeoff area, apron/ramp, or movement area used for takeoff, landing, or parking of helicopters. (AIM) 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 be made visually. It is prescribed and approved for a specific airport by competent authority. (AIM) INSTRUMENT FLIGHT RULES (IFR) : Rules governing the procedures for conducting instrument flight. Also term used by pilots and controllers to indicate a type of flight plan. (AIM) INSTRUMENT LANDING SYSTEM (ILS) : A precision instrument approach system which normally consists of the following electronic components and visual aids: (1) Localizer; (2) Glide Slope; (3) Outer Marker; (4) Middle Marker; (5) Approach Lights. (AIM) INSTRUMENT OPERATION : An aircraft operation in accordance with an IFR flight plan or an operation where IFR separation between aircraft is provided by a terminal control facility. (FAA ATA) INSTRUMENT RUNWAY : A runway equipped with electronic and visual navigation aids for which a precision or non-precision approach procedure having straight-in landing minimums has been approved. (AIM) ITINERANT OPERATION : An arrival or departure performed by an aircraft from or to a point beyond the local airport area. LARGE AIRCRAFT : An aircraft of more than 12,500 pounds maximum certificated takeoff weight. (FAR 1) LIMITED REMOTE COMMUNICATIONS OUTLET (LRCO) : An unmanned, remote air/ground communications facility which may be associated with a VOR. It is capable only of receiving communications and relies on a VOR or a remote transmitter for full capability. LOCALIZER (LOC) : The component of an ILS which provides course guidance to the runway. (AIM) LOCAL OPERATION : An arrival or departure performed by an aircraft: (1) operating in the traffic pattern, (2) known to be departing or arriving from flight in local practice areas, or (3) executing practice instrument approaches at the airport. (FAA ATA) LORAN: An electronic ground-based navigational system established primarily for marine use but used extensively for VFR and limited IFR air navigation. MARKER BEACON (MB) : The component of an ILS which informs pilots, both aurally and visually, that they are at a significant point on the approach course. MEAN SEA LEVEL (MSL) : An elevation datum given in feet from mean sea level. A-6 Eugene Airport Master Plan Update (February 2010)
