ALERT Heathrow Airport is experiencing a technical issue preventing runway alternation

London's main airport is experiencing a technical issue that is preventing the scheduled switching of runways, causing landings and departures to continue on the same runways (27R for landings and 27L for departures) until 18:00 local time. Normally, the airport alternates runway use at 15:00, but this will not occur due to the ongoing problem. From a transportation perspective, runway management is crucial for maintaining efficient air traffic flow and minimizing delays. When disruptions like this happen, it can lead to longer wait times for both arrivals and departures, affecting not just passengers but also cargo operations. It is essential for airports to have robust technical support and contingency plans to address such issues swiftly, as prolonged disruptions can have a cascading effect on schedules throughout the aviation network.
