MATZ military aerodrome traffic zone. An area of protected airspace surrounding certain military airfields which normally extends for a five nautical mile radius around the airfield and upwards from the surface to 3,000 feet above aerodrome level. A 'stub' projection protects the final approach path to the main runway outwards from the MATZ boundary, enclosing an area two nautical miles either side of the extended runway centreline and upwards from 1,000 feet above the surface to 3,000 feet above aerodrome elevation. Although recognition of a MATZ is not mandatory for civil aircraft, all MATZ aerodromes offer a penetration service to civil traffic during operational hours. Mayday international radio distress call (from the French, m'aidez -- help me). It signifies imminent danger to life requiring immediate assistance. mb millibar MCC Multi-crew co-operation MCU management control unit MDA minimum descent altitude. The lowest altitude, in feet amsl, to which descent is authorised on final approach during a non-precision instrument landing (i.e. where no glideslope guidance is given) without visual reference to the runway. MDH minimum descent height, agl. MEDA military emergency diversion airfield medevac medical evacuation Met meteorology, weather. METAR coded aerodrome Met report. Also SPECI, special civil aviation weather report, and TAF, terminal aerodrome forecast of weather expected. MF medium frequency. Radio waves with frequencies in the 300- 3,000 kHz range. MFA military flying area MFD multi-function display. An EFIS CRT offering selectable displays of weather radar, navigation maps, checklists and data other than primary flight information. MH magnetic heading MHz Megahertz, the frequency of radio carrier waves measured in millions of cycles per second. minimums weather condition requirements for a particular mode of flight (e.g. for VFR operation, IFR take-offs and landings). |
