Chiayi Airport at a glance
Chiayi Airport is a medium airport in Shuishang, Chiayi County, Taiwan, known to airline systems as CYI. The field elevation of 85 ft (26 m) is the number every arriving pilot dials against QNH — circuit heights and initial approach altitudes at RCKU 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 3 runways, the longest — 18R/36L — offers 10,007 ft (3050 m) of con surface, with runway lighting for night operations. Runway numbers give magnetic orientation: runway 18R points roughly 180° magnetic.
For the weather side of planning, the live METAR and TAF page for RCKU 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 Chiayi Airport
Density altitude is the quiet performance-killer at any field: on a hot day the 85 ft field elevation of Chiayi 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.

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.
