Concept definition: The higher degree identification of a <RUNWAY>; runway high end identifier. The value is formatted in a Basic Latin string that begins with a two-character identifier ranging from 19-36, determined from the approach direction, derived from the <RUNWAY> magnetic heading (high end) rounded to the nearest ten arc degrees, and divided by ten. Designated in accordance with appropriate host nation documents. Analyst derived <RUNWAY> numbers will use six arc degrees as the break off point for the next highest number. In the case of parallel runways, a third character is added to differentiate between left (L), right (R), centre (C), or STOL (S) <RUNWAY> positions. A fourth character, (T) True is added when the <RUNWAY> identifier and heading are true with no magnetic variation applied.
