An "approach plate" depicting an instrument approach procedure for an ILS approach to Tacoma Narrows Airport in the United StatesIn 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 ...
An approach plate for the ILS or LOC approach to runway 14L at Cologne Bonn Airport, Germany.. Approach plates (or, more formally, instrument approach procedure charts) are the printed or digital charts of instrument approach procedures that pilots use to fly instrument approaches during instrument flight rules (IFR) operations.
ILS planes. An instrument landing system operates as a ground-based instrument approach system that provides precision lateral and vertical guidance to an aircraft approaching and landing on a runway, using a combination of radio signals and, in many cases, high-intensity lighting arrays to enable a safe landing during instrument meteorological conditions (IMC), such as low ceilings or reduced ...
An aircraft approach category is a grouping which differentiates aircraft based on the speed at which the aircraft approaches a runway for landing. They are used to determine airspace, obstacle clearance and visibility requirements for instrument approaches . [ 1 ] :

The approach portion of an IFR flight may begin with a standard terminal arrival route (STAR), describing common routes to fly to arrive at an initial approach fix (IAF) from which an instrument approach commences. An instrument approach terminates either by the pilot acquiring sufficient visual reference to proceed to the runway, or with a ...
In aviation, reference datum height (RDH) is the height of a point, located above the intersection of the runway centre line and the threshold, through which the downward extended straight portion of the glide path passes. [1]
The Initial Approach Fix (IAF) is the point where the initial approach segment of an instrument approach begins. An instrument approach procedure may have more than one Initial approach fix and initial approach segment. The initial approach fix is usually a designated intersection, VHF omnidirectional range (VOR), non-directional beacon (NDB ...
