Flight-planning notes for Wonju Airport / Hoengseong Air Base (K-38/K-46)
Density altitude is the quiet performance-killer at any field: on a hot day the 329 ft field elevation of Wonju Airport / Hoengseong Air Base (K-38/K-46) 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.

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.
