Flight-planning notes for Tokunoshima Airport
Density altitude is the quiet performance-killer at any field: on a hot day the 17 ft field elevation of Tokunoshima 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 108 airports and airfields we list for Japan — 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.
