About Kualanamu International Airport

Overview

Kualanamu International Airport serves as the primary international airport for Medan, located in North Sumatra, Indonesia. Positioned at 3.637847°N, 98.870566°E, the airport provides critical air transportation infrastructure for the region, with its large airport classification supporting both domestic and international commercial operations.

Flying Conditions

The airport's low elevation of 23 feet mean sea level (MSL) indicates a relatively flat terrain environment typical of coastal Indonesian regions. Pilots should anticipate potential humidity and tropical weather patterns characteristic of the equatorial climate, which can produce rapid meteorological changes and occasional convective activity.

Notable Features

The airport features a single substantial runway (05/23) measuring 12,303 feet in length, constructed with asphalt and concrete surface materials. Its extended runway length provides significant operational flexibility for various aircraft types, supporting wide-body international and regional aircraft movements.

Approach Considerations

Given the runway's 05/23 orientation, approach and departure paths will be aligned approximately along the east-west axis. The substantial runway length of 12,303 feet offers considerable margin for safe operations, accommodating diverse aircraft performance characteristics and providing extended landing and takeoff capabilities.
