Wonsan Kalma Airport at a glance
Wonsan Kalma Airport is a medium airport in Wonsan, Kangwon Province, North Korea, known to airline systems as WOS. The field elevation of 7 ft (2 m) is the number every arriving pilot dials against QNH — circuit heights and initial approach altitudes at ZKWS are all figured from it. The airport handles scheduled commercial service, so expect controlled procedures, published approaches and commercial traffic in the pattern.
Of its 2 runways, the longest — 15L/33R — offers 11,482 ft (3500 m) of con surface, without recorded lighting. Runway numbers give magnetic orientation: runway 15L points roughly 150° magnetic.

Flight-planning notes for Wonsan Kalma Airport
Density altitude is the quiet performance-killer at any field: on a hot day the 7 ft field elevation of Wonsan Kalma Airport can translate into a substantially higher density altitude, stretching take-off rolls and flattening climb rates — run the numbers rather than trusting the feel of a standard day. Expect published instrument procedures, controlled airspace and clearance requirements; slots and handling may apply to general aviation traffic.
This entry is one of 17 airports and airfields we list for North Korea — the country index on the airports hub links the rest. Coordinates above are given in both DMS and decimal degrees so they can go straight into a GPS, a flight planner or a chart plot without conversion.
Where this data comes from
The reference layer behind this page builds on the OurAirports dataset — a public-domain, community-maintained register of the world's airports that many flight planners and apps rely on — with equity records preserved from documented historical listings where the dataset is silent. Figures are carried as published: elevations as surveyed, coordinates as filed, runway dimensions as recorded. Nothing is estimated to fill a gap, and the whole layer regenerates from source on every site build, so corrections upstream arrive here automatically.
