摘要

Heathrow is the busiest two-runway airport in the world, handling over 470,000 flights a year. It is also scheduled to c.99% of its capacity, meaning that anything that impacts the number of aircraft that land per hour can result in delays and an increased chance of cancellations. When the landing rate is constrained by weather, air traffic flow management (ATFM) regulations have to be applied to meter the flow of flights, resulting in delays to inbound shorthaul flights. Typically, weather results in about 400,000 minutes of ATFM delay at Heathrow every year, with the biggest cause being the impact of headwinds on approach, which accounts for c. 180,000 minutes.
