About London Stansted Airport

Overview

London Stansted Airport serves as a major international airport located northeast of central London. Positioned at 51.884998, 0.235000 with an elevation of 348 feet MSL, the airport handles significant commercial and cargo traffic. Its substantial 10,003-foot runway (04/22) supports large commercial aircraft operations.

Flying Conditions

As an airport in southeastern England, Stansted experiences typical maritime temperate climate conditions with potential for variable visibility and wind patterns. The airport's elevation at 348 feet means pilots should anticipate potential wind shear and thermal variations, particularly during seasonal transitions. Asphalt surface (ASP) runway provides standard friction characteristics.

Notable Features

The airport's single runway (04/22) offers substantial length at 10,003 feet, accommodating wide-body and long-haul aircraft types. Its geographic location northeast of London provides strategic positioning for regional and international routes. The terrain surrounding the airport is generally flat, characteristic of the Essex countryside.

Approach Considerations

Runway 04/22's significant length allows flexible approach options for various aircraft categories. Prevailing winds in the region may influence runway selection, with pilots recommended to obtain current meteorological information before approach. Standard instrument approach procedures will apply given the airport's international classification.
