Quad City International Airport at a glance

Quad City International Airport is a medium airport in Moline, Illinois, United States, known to airline systems as MLI. The field elevation of 590 ft (180 m) is the number every arriving pilot dials against QNH — circuit heights and initial approach altitudes at KMLI 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 — 09/27 — offers 10,002 ft (3049 m) of pem surface, with runway lighting for night operations. Runway numbers give magnetic orientation: runway 09 points roughly 90° magnetic.

Flight-planning notes for Quad City International Airport

Density altitude is the quiet performance-killer at any field: on a hot day the 590 ft field elevation of Quad City International 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.
