Yambio Airport (HSYA)

Yambio Airport at a glance

Yambio Airport is a small airport / airfield in Yambio, Western Equatoria State, South Sudan. The field elevation of 2,375 ft (724 m) is the number every arriving pilot dials against QNH — circuit heights and initial approach altitudes at HSYA are all figured from it. There is no scheduled airline service listed here — typical traffic is general aviation, training and local operations.

No runway records exist for this entry in the source dataset — common for fields whose operators never filed dimensions with the public dataset. The absence of a record says nothing about the runway on the ground: it may be paved, lighted and perfectly serviceable. Treat published charts, national AIP entries and the operator as the authoritative sources for runway data here, and this page as the identity and position reference for the field at Yambio. When the dataset gains a runway record for this field, the next site build picks it up automatically — the reference layer regenerates from source on every rebuild rather than being edited by hand.

For the weather side of planning, the live METAR and TAF page for HSYA shows the current observation decoded line by line — wind on an instrument dial, visibility, cloud layers and the resulting flight rules — refreshed continuously from official sources.

Flight-planning notes for Yambio Airport

Density altitude is the quiet performance-killer at any field: on a hot day the 2,375 ft field elevation of Yambio 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. As with most small fields, the recorded details can lag reality — surfaces get resurfaced, thresholds move and operating hours change — so a call ahead to the field operator is part of the plan, not a courtesy.

This entry is one of 6 airports and airfields we list for South Sudan — 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.
