Missed Approach Point
Missed approach point (MAP or MAPt) is the point prescribed in each instrument approach at which a missed approach procedure shall be executed if the required visual reference does not exist. It defines the point for both precision and non-precision approaches wherein the missed approach segment of an approach procedure begins. A pilot must execute a missed approach if a required visual reference (normally the runway or its environment) is not in sight upon reaching the MAP or the pilot decides it is unsafe to continue with the approach and landing to the runway. The missed approach point is published in the approach plates and contains instructions for missed approach procedures to be executed at this point. Definition of MAP depends on whether the approach flown is a precision or a non-precision one: * Non-precision approach. The MAP for a non-precision approach is typically crossed at the minimum descent altitude (MDA), and may be anywhere from well prior to the runway thres ...

Instrument Approach
In aviation, an instrument approach or instrument approach procedure (IAP) is a series of predetermined maneuvers for the orderly transfer of an aircraft operating under instrument flight rules from the beginning of the initial approach to a landing, or to a point from which a landing may be made visually. These approaches are approved in the European Union by EASA and the respective country authorities and in the United States by the FAA or the United States Department of Defense for the military. The ICAO defines an instrument approach as, "a series of predetermined maneuvers by reference to flight instruments with specific protection from obstacles from the initial approach fix, or where applicable, from the beginning of a defined arrival route to a point from which a landing can be completed and thereafter, if landing is not completed, to a position at which holding or enroute obstacle clearance criteria apply."

Missed Approach
Missed approach is a procedure followed by a pilot when an instrument approach cannot be completed to a full-stop landing. The instructions for the missed approach may be assigned by air traffic control (ATC) prior to the clearance for the approach. If ATC has not issued specific instructions prior to the approach and a missed approach is executed, the pilot must follow the (default) missed approach procedure specified for the approach. Prior to commencing the approach, pilots can make a specific request to ATC if a missed approach may occur. Such a request may include heading and altitude instructions to avoid in-flight delays (such as holds) and efficiently maneuver the aircraft into position for either its next approach or a diversion to an alternate airport. Generally, if a pilot determines by the time the aircraft is at the decision height (for a precision approach) or missed approach point (for a non-precision approach), that the runway or its environment is not in sight, or ...

Runway
According to the International Civil Aviation Organization (ICAO), a runway is a "defined rectangular area on a land aerodrome prepared for the landing and takeoff of aircraft". Runways may be a man-made surface (often asphalt concrete, asphalt, concrete, or a mixture of both) or a natural surface (sod, grass, soil, dirt, gravel, ice, sand or road salt, salt). Runways, as well as taxiways and Airport apron, ramps, are sometimes referred to as "tarmac", though very few runways are built using Tarmacadam, tarmac. Takeoff and landing areas defined on the surface of water for seaplanes are generally referred to as waterways. Runway lengths are now International Civil Aviation Organization#Use of the International System of Units, commonly given in meters worldwide, except in North America where feet are commonly used. History In 1916, in a World War I war effort context, the first concrete-paved runway was built in Clermont-Ferrand in France, allowing local company Michelin to ...

Approach Plate
Approach plates (or, more formally, instrument approach procedure charts) are the printed charts of instrument approach procedures that pilots use to fly instrument approaches during instrument flight rules (IFR) operations. Each country maintains its own instrument approach procedures according to International Civil Aviation Organization (ICAO) standards. In the United States, these procedures are published by the Federal Aviation Administration, military services, commercial aviation publishing organizations, and other organizations. Generally, instrument approach procedures to civil airports in the U.S. are approved by the FAA, and instrument approach procedures to military airports in the U.S. are approved by the appropriate military service. The FAA may also approve private instrument approaches to private airports or heliports for authorized users of these private facilities. These private instrument approach procedures are generally not published but are made available ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Glideslope
Instrument landing system glide path, commonly referred to as a glide path (G/P) or glide slope (G/S), is "a system of vertical guidance embodied in the instrument landing system which indicates the vertical deviation of the aircraft from its optimum path of descent", according to ''Article 1.106'' of the ITU Radio Regulations (ITU RR).ITU Radio Regulations, Section IV. Radio Stations and Systems – Article 1.106, definition: ''instrument landing system (ILS)'' Principle of operation A glide slope station uses an antenna array sited to one side of the runway touchdown zone. The GS signal is transmitted on a carrier signal using a technique similar to that for the localizer. The centre of the glide slope signal is arranged to define a glide path of approximately 3° above horizontal (ground level). The beam is 1.4° deep (0.7° below the glide-path centre and 0.7° above). The pilot (or the autopilot, if using autoland) controls the aircraft so that the glide slope indicator r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
