About London Heathrow Airport

Overview

London Heathrow Airport serves as the United Kingdom's primary international aviation hub, located in western London at 83 feet mean sea level. As a large airport handling extensive international and domestic traffic, Heathrow operates two parallel asphalt runways capable of supporting heavy commercial aircraft operations. Its strategic location and substantial infrastructure make it a critical transportation gateway for the Greater London metropolitan area.

Flying Conditions

Weather conditions at Heathrow demonstrate significant variability, with Visual Flight Rules (VFR) prevailing 50.1% of the time and Marginal VFR conditions occurring 29.8% of observations. Temperature ranges from -5°C to 27°C with an average of 9.6°C, presenting potential seasonal operational considerations. Wind patterns are predominantly from the south at 180° with an average speed of 8.5 knots, and both runways maintain 100% favorable wind alignment.

Notable Features

Heathrow features two parallel runways (09L/27R and 09R/27L) measuring 12,799 feet and 12,001 feet respectively, providing substantial operational flexibility. The airport's low elevation of 83 feet MSL and geographic positioning near London contribute to relatively stable approach characteristics. Visibility averages 10 statute miles, with minimal occurrences of severely restricted visibility (fog present in only 1.6% of observations).

Approach Considerations

Pilots can expect consistently favorable wind conditions across both runways, with an average crosswind of 5.8 knots. September through November represent the most reliable months for Visual Flight Rules operations. The airport's wind profile and runway configuration offer predictable approach and departure environments, with both runways demonstrating equivalent wind alignment and crosswind characteristics.
