The impacts are already too large at two runways, and the air travel industry is evolving to reduce the need for Heathrow as a major international hub. So, let’s be done with this ridiculous idea of adding a third parallel runway.
Consider how technologies have changed. There was a time in the U.S. when all transcontinental flights had to stop at ‘hubs’ in the mid-continent, making for very busy airports in places like Wichita, Kansas. These former hubs are now all but ‘ghost-airports’, because we developed more powerful engines and larger fuel capacities, enabling much longer flights.
London’s Heathrow Airport should follow that same path, and the role of this airport as a major international hub should decline substantially. Geography made London a logical (and necessary) refueling hub location for Transatlantic flights, but that necessity has ended in recent decades. We now have direct flights from the U.S. West Coast to Frankfurt, Amsterdam, Oslo, Copenhagen, Munich, Istanbul, Dubai, etc. So, we really do not need to stop anymore, in London or Dublin or even Iceland.
It makes far more sense for flights between North America and Europe to carry passengers directly from actual origin cities to actual destination cities. The carbon impact is minimized, the air traveler’s time-cost is minimized, and noise impacts upon airport neighbors are also minimized. And one more benefit: an evolved system with more thin routes takes pressure off of major U.S. hubs like KJFK, KBOS, KCLT, KORD, KPHX, and KSFO … and this has potential to greatly reduce the local impacts being magnified by the ongoing NextGen implementation debacles.
We can have better air service for people. We can minimize impacts on neighborhoods and the planet. The key to moving forward on this is to get national regulators and politicians to quit perpetuating inefficiencies, to quit subsidizing the airlines with excessive airport expansion. And in the UK, this means:
NO THIRD RUNWAY at HEATHROW!!
The ‘machine’ that keeps pressing for a third Heathrow runway is motivated by greed. Here is a copy of a recent news article about their campaign efforts, with analytical footnotes added by aiREFORM.
