MINIMUM SAFE ALTITUDE WARNING-A function of the ARTS III computer that aids the controller by alerting him/her when a tracked Mode C equipped aircraft is below or is predicted by the computer to go below a predetermined minimum safe altitude. (Refer to AIM.) 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 operation; e.g., IFR takeoff or landing, alternate airport for IFR flight plans, VFR flight, etc. (See IFR CONDITIONS.) DEPARTURE PROCEDURES.) 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.
MISSED APPROACH- b.. c.
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. MISSED APPROACH PROCEDURE [ICAO]- The procedure to be followed if the approach cannot be continued. |
