- Instrument_approach abstract "An Instrument Approach, or Instrument Approach Procedure (IAP), is \"a series of predetermined maneuvers for the orderly transfer of an aircraft under instrument flight conditions 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 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.\"There are three types of IAPs: Precision Approach (PA), Approach with Vertical Guidance (APV), and Nonprecision Approach (NPA). A PA uses a navigation system which provides course and glidepath deviation. Examples include Precision Approach Radar (PAR), Instrument Landing System (ILS), and Ground Based Landing System (GLS). An APV also uses a navigation system for course and glidepath deviation, just not to the same standards as a PA. Examples include Baro-VNAV, Localizer type Directional Aid (LDA) with glidepath, LNAV/VNAV and LPV. An NPA uses a navigation system for course deviation but does not provide glidepath information. These approaches include VOR, NDB and LNAV. NPAs are flown to a Minimum Descent Altitude (MDA).IAP Charts are Aeronautical Charts which portray \"the aeronautical data which is required to execute an instrument approach to an airport.\" Besides depicting topographic features, hazards and obstructions, they depict the procedures and airport diagram. Each procedure chart uses a specific tyoe of electronic navigation system such as an NDB, TACAN, VOR, ILS/MLS and RNAV or Area Navigation. The chart name will reflect the primary Navigational Aid (NAVAID), if there is more than one straight-in procedure or if it is just a circling-only procedure. A communication strip on the chart lists frequencies in the order they are used. Minimum, maximum and mandatory altitudes are depicted in addition to the Minimum Safe Altitude (MSA) for emergencies. A cross depicts the Final Approach Fix (FAF) altitude on NPAs while a lightning bolt does the same for PAs. NPAs depict the MDA while a PA will show both the Decision Altitude (DA) and Decision Height (DH). Finally, the chart will depict the Missed approach procedures in plan and profile view, besides listing the steps in sequence.Before satellite navigation was available for civilian aviation, the requirement for large land-based navigation aid (\"navaid\") facilities generally limited the use of instrument approaches to land-based (i.e. asphalt, gravel, turf, ice) runways (and those on aircraft carriers). GNSS technology allows, at least theoretically, to create instrument approaches to any point on the Earth's surface (whether on land or water); consequently, there are nowadays examples of water aerodromes (such as Rangeley Lake Seaplane Base in Maine, USA) that have GNSS-based approaches.".
