Satellites Could Show Airplanes Faster Long-Haul Routes in Mid-Air

The promise of powerful satellite constellations orbiting hundreds of miles above the earth can seem, well, a little distant. But what if they could make long-haul flights faster? From a report:Operators like Iridium and Inmarsat are promising that jet liners linked to space communications networks can save fliers money, time and carbon impact, as more efficient flights cut fuel use. Today, an airliner flying five miles over the open ocean, beyond the reach of the radar systems used by civil air controllers, is dependent on flight plans written well before take-off, and what pilots could report over the radio to scattered air traffic controllers. Weather bulletins still arrive in the cockpit as brief text messages. But a true global communications network -- one orbit around the earth -- could give pilots the flexibility to react to changing situations in real time, the same way Google Maps now allows drivers to re-route around traffic jams as they drive.
