Terms for subject Aviation (1835 entries)
minimum navigation performance specifications An expression used to designate specifications relating to the navigation performance capability of aircraft operating in specified portions of the airspace
minimum obstacle clearance altitude The altitude above sea level (ASL) between specified fixes on airways or air routes that meets the IFR obstacle clearance requirements for the route segment in question
minimum reception altitude When applied to a specific VHF/UHF intersection, the lowest altitude above sea level (ASL) at which acceptable navigational signal coverage is received to determine the intersection
minimum safe altitude An altitude depicted on approach charts that provides at least 1000 ft of obstacle clearance for use within a specified distance from the navigation facility upon which a procedure is predicated
Minimum Safe Altitude as defined in the FLIP General Planning Document MSA
minimum safe altitude warning A function of certain ATC automated systems that is designed to alert radar controllers to existing or pending penetrations of a minimum safe altitude that is recognized by program parameters and requires immediate attention or action
minimum safe speed The minimum speed at which an aircraft may be operated without affecting its manoeuvring ability. This speed may vary depending on the aircraft type and configuration, or emergency conditions.
minimum sector altitude The lowest altitude that will provide a minimum clearance of 1000 ft under conditions of standard temperature and pressure above all objects located in an area contained within a sector of a circle with a 25 NM radius centred on a radio aid to navigation or a specified point
minimum vectoring altitude The lowest altitude for vectoring aircraft by ATC that meets obstacle clearance and radio coverage requirements in the airspace specified
missed approach That part of an instrument approach procedure (IAP) between the missed approach point (MAP) the missed approach waypoint (MAWP) or the point of arrival at decision height (DH) and the specified missed approach NAVAID, intersection, fix or waypoint, as appropriate, at the minimum IFR altitude. It is in this part of the approach procedure that the aircraft climbs and returns to the en route structure or is positioned for holding or a subsequent approach. The route of flight and altitudes are depicted on instrument approach charts.
missed approach holding waypoint The waypoint designated in the missed approach segment of an instrument approach procedure (IAP) to which the aircraft will automatically fly and, upon reaching the geographic position of the waypoint, enter a specified holding pattern
missed approach point The point on the final approach course that signifies the termination of the final approach and the commencement of the missed approach segment. It may be (a) the intersection of an electronic glide path (GP) with a decision height (DH) a NAVAID located on the aerodrome; (c) a suitable fix (e.g. distance measuring equipment (DME)) or (d) a specified distance beyond the NAVAID or final approach fix (FAF) not to exceed the distance from that NAVAID or fix to the nearest boundary of the aerodrome. • U.S.: abbreviation: MAP • ICAO: abbreviation: MAPt or MAPT
missed approach procedure The procedure that is to be followed after an instrument approach procedure (IAP) if, for any reason, a landing is not effected and that occurs normally (a) when the aircraft has descended to the decision height (DH) or has descended to the minimum descent altitude (MDA) and reached the missed approach point or waypoint, and has not established the required visual reference to land; or (b) when the aircraft is directed by ATC to pull up or to go around
missed approach segment That part of an instrument approach procedure (IAP) between the missed approach point (MAP) the missed approach waypoint (MAWP) or the point of arrival at decision height (DH) and the specified missed approach NAVAID, intersection, fix or waypoint, as appropriate, at the minimum IFR altitude. It is in this part of the approach procedure that the aircraft climbs and returns to the en route structure or is positioned for holding or a subsequent approach. The route of flight and altitudes are depicted on instrument approach charts.
missed approach turning waypoint The waypoint designated in the missed approach segment of an instrument approach procedure (IAP) to which the aircraft will automatically fly en route to the specified missed approach holding waypoint
missed approach waypoint The waypoint on the final approach course that signifies the termination of the final approach segment and the commencement of the missed approach segment. It is normally located at the threshold of the landing runway.
missile growl An audible cue produced by the Sidewinder seeker head
missing aircraft notice A message issued by a joint rescue coordination centre (JRCC) to ATS units, giving details of a missing aircraft
Mission Ready/Mission Support MR/MS
