Three-quarters of flight delays are due to weather. While we can't convince SFO's fog to burn off according to our schedules, there most certainly is a better way to plan around it. At The Atlantic's Big Science Summit in San Jose, California, Parimal Kopardekar, the principal investigator at NASA's NextGen Airspace Project, explained that by pulling data -- weather forecasts, ground-based forecasts, readings from sensors placed outside planes -- a model could be created to predict the best course of action for any particular flight.
With enough information, says Kopardekar, the system could see "automation that detects and resolves conflicts." A computer could figure out, for instance, whether it would be faster to wait for ten minutes on the tarmac for a storm to pass or take off immediately and make a slight detour in the air. That kind of data-based decision making could work not just for departures, but for arrivals, too, so a flight from New York to San Francisco could be timed to arrive right as the Bay Area's fog clears.
