Encoding of Runway Information
In abbreviated output formats, runway information is encoded as in the following example::
This means runway 03/21 is 6899 feet long by 75 feet wide, is surfaced with asphalt. Surface abbreviations include:
If the runway is equipped with edge lighting, the "x" between the length and width dimensions is replaced with an asterisk. If the either end of the runway requires a right-hand pattern, an "R" prefix is added before that end. If both ends use right traffic, a "!" prefix is added. For example:
means the runway is equipped with edge lighting, and uses right-hand traffic for runway 21.
