When unavoidable bad weather causes turbulence in the air, passengers can expect a rocky ride. In the past, while pilots have aimed to avoid turbulence, they have been limited in the number of available tools. Now, a new turbulence avoidance system promises to change that.
A smoother ride
Called the Juneau Airport Wind System (JAWS), it was developed by the National Center for Atmospheric Research (NCAR) and provides information pilots can use to route aircraft away from patches of potentially dangerous turbulence.
“By alerting pilots to areas of moderate and severe turbulence, this system enables them to fly more frequently and safely in and out of the Juneau airport in poor weather,” says Alan Yates, an NCAR program manager who helped oversee the system’s development in an R&D Magazine article. “It allows pilots to plan better routes, helping to reduce the bumpy rides that passengers have come to associate with airports in these mountainous settings.”
The system uses a network of wind measuring instruments and computational formulas to interpret rapidly changing atmospheric conditions. The Federal Aviation Administration accepted JAWS for operational use this year.

In the works and delayed for several years, another system relies on satellites and GPS rather than the radar system developed in the 1950s to direct planes and jets from takeoff to landing.
Called the NextGen system, it will be initially used in Orlando, Washington, D.C., Atlanta, northern and southern California, Houston, Charlotte and northern Texas. The new system should allow planes to fly with less spacing between them on more direct routes, and allowing them to glide to a landing rather than following a step down pattern that is not fuel efficient.
The NextGen system has been compared to walking down a flight of stairs vs. sliding down the banister.
“In addition to improving safety and increasing capacity, this plan will allow for more direct routing for airplanes, less holding at the destination and better planning for constant descent arrivals mentioned above, resulting in less carbon emissions, fuel consumption, and noise.” said Gadling’s Kent Wien in Plane Answers: Airlines see green in appearing green back in 2009, just to show how long this one has been in the works.
