MINIMUM SECTOR ALTITUDE [ICAO]. The lowest altitude which may be used under emergency conditions which will provide a minimum clearance of 300 m (1,000 feet) above all obstacles located in an area contained within a sector of a circle of 46 km (25 NM) radius centered on a radio aid to navigation. MINIMUMS. Weather condition requirements established for a particular operation or type of PCG M.4 operation; e.g., IFR takeoff or landing, alternate airport for IFR flight plans, VFR flight, etc. (See IFR CONDITIONS.)(See IFR TAKEOFF MINIMUMS AND DEPARTURE PROCEDURES.)(See LANDING MINIMUMS.)(See VFR CONDITIONS.)(Refer to 14 CFR Part 91.)(Refer to AIM.)MINIMUM VECTORING ALTITUDE (MVA). The lowest MSL altitude at which an IFR aircraft will be vectored by a radar controller, except as otherwise authorized for radar approaches, departures, and missed approaches. The altitude meets IFR obstacle clearance criteria. It may be lower than the published MEA along an airway or J-route segment. It may be utilized for radar vectoring only upon the controller’s determination that an adequate radar return is being received from the aircraft being controlled. Charts depicting minimum vectoring altitudes are normally available only to the controllers and not to pilots. (Refer to AIM.)MINUTES-IN-TRAIL. A specified interval be-tween aircraft expressed in time. This method would more likely be utilized regardless of altitude. MIS. (See METEOROLOGICAL IMPACT STATEMENT.)MISSED APPROACH. a.A maneuver conducted by a pilot when an instrument approach cannot be completed to a landing. The route of flight and altitude are shown on instrument approach procedure charts. A pilot executing a missed approach prior to the Missed Approach Point (MAP) must continue along the final approach to the MAP. b.A term used by the pilot to inform ATC that he/she is executing the missed approach. c.At locations where ATC radar service is provided, the pilot should conform to radar vectors when provided by ATC in lieu of the published missed approach procedure. (See MISSED APPROACH POINT.)(Refer to AIM.)Pilot/Controller Glossary MISSED APPROACH POINT. A point prescribed in each instrument approach procedure at which a missed approach procedure shall be executed if the required visual reference does not exist. (See MISSED APPROACH.)(See SEGMENTS OF AN INSTRUMENT APPROACH PROCEDURE.)MISSED APPROACH PROCEDURE [ICAO]. The procedure to be followed if the approach cannot be continued. MISSED APPROACH SEGMENT. (See SEGMENTS OF AN INSTRUMENT APPROACH PROCEDURE.)MLDI. (See METER LIST DISPLAY INTERVAL.)MLS. (See MICROWAVE LANDING SYSTEM.)MLS CATEGORIES. a.MLS Category I. An MLS approach procedure which provides for an approach to a height above touchdown of not less than 200 feet and a runway visual range of not less than 1,800 feet. b.MLS Category II. Undefined until data gather-ing/analysis completion. c.MLS Category III. Undefined until data gathering/analysis completion. MM. (See MIDDLE MARKER.)MNPS. (See MINIMUM NAVIGATION PERFORMANCE SPECIFICATION.)MNPSA. (See MINIMUM NAVIGATION PERFORMANCE. SPECIFICATION AIRSPACE.)MOA. (See MILITARY OPERATIONS AREA.)MOCA. (See MINIMUM OBSTRUCTION CLEARANCE ALTITUDE.)MODE. The letter or number assigned to a specific pulse spacing of radio signals transmitted or received by ground interrogator or airborne transponder components of the Air Traffic Control Radar Beacon PCG M.5 System (ATCRBS). Mode A (military Mode 3) and Mode C (altitude reporting) are used in air traffic control. (See INTERROGATOR.)(See RADAR.)(See TRANSPONDER.)(See ICAO term MODE.)(Refer to AIM.)MODE (SSR MODE) [ICAO]. The letter or number assigned to a specific pulse spacing of the interrogation signals transmitted by an interrogator. There are 4 modes, A, B, C and D specified in Annex 10, corresponding to four different interrogation pulse spacings. MODE C INTRUDER ALERT. A function of certain air traffic control automated systems designed to alert radar controllers to existing or pending situations between a tracked target (known IFR or VFR aircraft) and an untracked target (unknown IFR or VFR aircraft) that requires immediate attention/ action. (See CONFLICT ALERT.)MONITOR. (When used with communication transfer) listen on a specific frequency and stand by for instructions. Under normal circumstances do not establish communications. MONITOR ALERT (MA). A function of the TFMS that provides traffic management personnel with a tool for predicting potential capacity problems in individual operational sectors. The MA is an indication that traffic management personnel need to analyze a particular sector for actual activity and to determine the required action(s), if any, needed to control the demand. MONITOR ALERT PARAMETER (MAP). The number designated for use in monitor alert processing by the TFMS. The MAP is designated for each operational sector for increments of 15 minutes. MOSAIC/MULTI.SENSOR MODE. Accepts posi-tional data from multiple radar or ADS.B sites. Targets are displayed from a single source within a radar sort box according to the hierarchy of the sources assigned. MOVEMENT AREA. The runways, taxiways, and other areas of an airport/heliport which are utilized for taxiing/hover taxiing, air taxiing, takeoff, and landing of aircraft, exclusive of loading ramps and parking areas. At those airports/heliports with a tower, specific approval for entry onto the movement area must be obtained from ATC. (See ICAO term MOVEMENT AREA.)MOVEMENT AREA [ICAO]. That part of an aerodrome to be used for the takeoff, landing and taxiing of aircraft, consisting of the maneuvering area and the apron(s). |
