Runway Data

The runway section contains detailed information about airport runways worldwide, including dimensions, orientation, and geographic coordinates.

Format Structure

Each runway record follows this pattern:

RWY ICAO##   LLLLLWWWHHHASP±LLLLLLLLL±LLLLLLLLLL

RWY ZBAA01   12467197359ASP+40058914+116617658

Field	Meaning	Notes / Examples
`RWY`	Record type identifier	Fixed string "RWY" identifying this as runway data
`ZBAA`	ICAO airport code	4-character ICAO identifier (e.g., `ZBAA` = Beijing Capital International Airport)
`01`	Runway number	2-digit runway designation (01-36), based on magnetic heading rounded to nearest 10°
`12467`	Runway length	Physical runway length in feet (e.g., `12467` = 12,467 feet)
`197`	Runway width	Physical runway width in feet (e.g., `197` = 197 feet)
`359`	Magnetic heading	3-digit runway magnetic bearing (000-359°)
`ASP`	Surface type	Runway surface material, always "ASP" (Asphalt) in PFPX data
`+40058914`	Threshold latitude	Runway threshold latitude coordinate ±DDDDDDDD (degrees × 1,000,000), + = North, - = South
`+116617658`	Threshold longitude	Runway threshold longitude coordinate ±DDDDDDDDD (degrees × 1,000,000), + = East, - = West

+40058914 → 40058914 ÷ 1,000,000 = 40.058914°N

+116617658 → 116617658 ÷ 1,000,000 = 116.617658°E
