About Noi Bai International Airport

Overview

Noi Bai International Airport serves as the primary international gateway for Hanoi, Vietnam, located in the Soc Son district. As a large airport with two concrete runways exceeding 10,000 feet, it supports significant commercial and international aviation operations. The airport sits at a low elevation of 39 feet mean sea level, providing generally stable approach conditions.

Flying Conditions

Weather statistics indicate highly favorable flying conditions, with 87.1% of observations supporting visual (VFR) or marginal visual (MVFR) flight rules. Temperatures range from 9°C to 35°C, with an average of 22.3°C, suggesting minimal thermal extreme challenges. The best VFR months are October, September, and November, offering optimal flying weather with consistent visibility averaging 10 statute miles.

Notable Features

The airport features two parallel runways oriented 11/29, with excellent wind alignment. Both runways demonstrate 100% favorable wind conditions and minimal average crosswind at 3.5 knots. Prevailing winds from the northeast (45 degrees) at an average of 5.6 knots support predictable and stable flight operations, with rare calm conditions (1.3% of observations).

Approach Considerations

Pilots can expect consistently favorable approach conditions with high visibility and minimal meteorological restrictions. Fog is extremely rare, occurring in only 0.4% of observations, and visibility below 3 statute miles is essentially non-existent. The parallel runway configuration provides operational flexibility, with both runways offering similar wind characteristics and approach potential.
