Missed Approach
Missed approach is a procedure followed by a pilot when an instrument approach cannot be completed to a full-stop landing. Initiation A missed approach may be either initiated by the pilot or instructed by air traffic control (ATC). The instructions for the missed approach may be assigned by 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 Instrument approach#Decision height or altitude (Precision Appr ...

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 Visual approach, visually. These approaches are approved in the European Union by EASA and the respective country authorities, and in the United States by the Federal Aviation Administration, 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 (aviation), holding or ''en route'' obstacle clearance criteri ...

Air Traffic Control
Air traffic control (ATC) is a service provided by ground-based air traffic controllers who direct aircraft on the ground and through a given section of controlled airspace, and can provide advisory services to aircraft in non-controlled airspace. The primary purpose of ATC is to prevent collisions, organise and expedite the flow of traffic in the air, and provide information and other support for pilots. Personnel of air traffic control monitor aircraft location in their assigned airspace by radar and communicate with the pilots by radio. To prevent collisions, ATC enforces Separation (air traffic control), traffic separation rules, which ensure each aircraft maintains a minimum amount of 'empty space' around it at all times. It is also common for ATC to provide services to all General aviation, private, Military aviation, military, and commercial aircraft operating within its airspace; not just civilian aircraft. Depending on the type of flight and the class of airspace, AT ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 before the runway thresho ...

Federal Aviation Administration
The Federal Aviation Administration (FAA) is a Federal government of the United States, U.S. federal government agency within the United States Department of Transportation, U.S. Department of Transportation that regulates civil aviation in the United States and surrounding international waters. Its powers include air traffic control, certification of personnel and aircraft, setting standards for airports, and protection of U.S. assets during the launch or re-entry of commercial space vehicles. Powers over neighboring international waters were delegated to the FAA by authority of the International Civil Aviation Organization. The FAA was created in as the Federal Aviation Agency, replacing the Civil Aeronautics Administration (United States), Civil Aeronautics Administration (CAA). In 1967, the FAA became part of the newly formed U.S. Department of Transportation and was renamed the Federal Aviation Administration. Major functions The FAA's roles include: *Regulating U.S. co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Approach Lighting System
An approach lighting system (ALS) is a lighting system installed on the approach end of an airport runway and consisting of a series of lightbars, strobe lights, or a combination of the two that extends outward from the runway end. ALS usually serves a runway that has an instrument approach procedure (IAP) associated with it and allows the pilot to visually identify the runway environment and align the aircraft with the runway upon arriving at a prescribed point on an approach. Modern approach lighting systems are highly complex in their design and significantly enhance the safety of aircraft operations, particularly in conditions of reduced visibility. Operation The required minimum visibilities for instrument approaches is influenced by the presence and type of approach lighting system. In the U.S., a CAT I ILS approach without approach lights will have a minimum required visibility of 3/4 mile, or 4000 foot runway visual range. With a 1400-foot or longer approach light s ...

Runway End Identifier Light
Runway end identifier lights (REIL) (ICAO identifies these as Runway Threshold Identification Lights) are installed at many airports to provide rapid and positive identification of the approach end of a particular runway. The system consists of a pair of synchronized flashing lights located laterally on each side of the runway threshold. REILs may be either omnidirectional or unidirectional facing the approach area.FAA Aeronautical Information Manual, Chapter 2 (Aeronautical Lighting and Other Airport Visual Aids), Section 1 (Airport Lighting Aids) They are effective for: * Identification of a runway surrounded by a preponderance of other ...

Visual Approach Slope Indicator
The visual approach slope indicator (VASI) is a system of lights on the side of an airport runway threshold that provides visual descent guidance information during final approach. These lights may be visible from up to during the day and up to or more at night. Standard VASI Basic visual approach slope indicators consist of one set of lights set up from the start of the runway. Each light is designed so that it appears as either white or red, depending on the angle at which it is viewed. When the pilot is approaching the lights at the proper angle, meaning the pilot is on the glide slope, the first set of lights appears white and the second set appears red. When both sets appear white, the aircraft is too high, and when both appear red it is too low. This used to be the most common type of visual approach slope indicator system; however, it is being phased out and replaced by precision approach path indicators (PAPIs), which are closer together and therefore more effici ...

Go-around
In aviation, a go-around is an aborted landing of an aircraft that is on Final_approach_(aeronautics), final approach or has already touched down. A go-around can either be initiated by the pilot flying or requested by air traffic control for various reasons, such as an unstabilized approach or an obstruction on the runway. Etymology The term arises from the traditional use of Airfield traffic pattern, traffic patterns at airfields. A landing aircraft will first join the traffic pattern/circuit and prepare for landing. If for some reason, the pilot decides not to land, the pilot can simply fly back up to traffic pattern altitude/circuit height, and complete another circuit. The term "go-around" is still used even for modern airliners, though they often do not use traditional traffic patterns/circuits for landing, instead using an airport-specific go-around procedure. Reasons for use Initiation of a go-around may be either ordered by air traffic control (normally the local or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
