METERING AIRPORTS- Airports adapted for metering and for which optimum flight paths are defined. A maximum of 15 airports may be adapted. METERING FIX- A fix along an established route from over which aircraft will be metered prior to entering terminal airspace. Normally, this fix should be established at a distance from the airport which will facilitate a profile descent 10,000 feet above airport elevation (AAE) or above. METERING POSITION(S)-Adapted PVDs/ MDMs and associated “D” positions eligible for display of a metering position list. A maximum of four PVDs/MDMs may be adapted. METERING POSITION LIST- An ordered list of data on arrivals for a selected metering airport displayed on a metering position PVD/MDM. MFT- (See METER FIX TIME/SLOT TIME.) MHA- (See MINIMUM HOLDING ALTITUDE.) MIA- (See MINIMUM IFR ALTITUDES.) MICROBURST- A small downburst with outbursts of damaging winds extending 2.5 miles or less. In spite of its small horizontal scale, an intense microburst could induce wind speeds as high as 150 knots (Refer to AIM.) MICRO‐EN ROUTE AUTOMATED RADAR TRACKING SYSTEM (MEARTS)- An automated radar and radar beacon tracking system capable of employing both short‐range (ASR) and long‐range (ARSR) radars. This microcomputer driven system provides improved tracking, continuous data record-ing, and use of full digital radar displays. MICROWAVE LANDING SYSTEM- A precision instrument approach system operating in the microwave spectrum which normally consists of the following components: a.. Azimuth Station. b.. c..
MIDDLE MARKER- A marker beacon that defines a point along the glideslope of an ILS normally located at or near the point of decision height (ILS Category I). It is keyed to transmit alternate dots and dashes, with the alternate dots and dashes keyed at the rate of 95 dot/dash combinations per minute on a 1300 Hz tone, which is received aurally and visually by compatible airborne equipment. |
