We Chased Storms In An Airplane To Test Out A New 3D Radar System
No matter. Flying in a 1952 Convair 580 that's "built like a tank," we left New York's LaGuardia Airport and flew toward a storm system in Virginia.
Honeywell's IntuVue 3D weather radar analyzes data from 17 different angled "slices" of space at once, showing all of the weather that's in front of the plane, from the ground all the way to 60,000 feet.
Traditional radar systems only look at one slice of space at once, making it hard to know without recalculating the radar if there's a storm above or below one's current position. Older systems can also be confused by the curvature of the planet, requiring more calculations and more adjustments from the pilot.
"At the end of the day, from a pilot's perspective [the new system] is a simpler radar to use. You can turn it on, not fool with it, and get what you need," says Bill Lusk, a pilot and manager of daily operations for Southwest Airlines, which has started to use the newest version of the IntuVue systems in its 737s. "Makes it simpler to determine the route you need while doing less work."
The new technology should make planes safer and also reduce weather-related delays, as airlines will be able to fly in bad weather more confidently and plan better routes.
The radar system itself fits into the nose of the plane. Even though it's a smaller plane, the Convair 580 has a 30-inch space in the nose for the radar, the same size as the space in most 737s and 757s. That's another reason why it makes a great test aircraft for products that will eventually go in big airliners. Below, you can see the radar screen itself. It's right in the center, between all the dials. The system sees a full 180 degree view of what's in front of the plane, including weather systems above and below the current altitude. Along with the radar there was a small tablet in the cockpit that tracks National Weather Service data. Honeywell coordinates its weather research with NWS, NASA, the EU, and other partners.Onboard, we had headsets at our seats that we could use to chat with each other during takeoff and landing. I got to hear what happens when someone forgets to put their phones in airplane mode. You get to hear that static sound that sometimes pops into speakers when a phone is looking for service.
Below is an example of what the radar looks like in action. In this example, provided by Honeywell, it shows a serious storm.Darker colors mean more intense weather, and little icons predict where hail and lightning will be found.
As for our flight, all we had was a fairly small and distant storm system, and we only got within about 80 miles of the weather itself. Normally planes try to miss a storm by 20 miles or more, so we were in a very safe spot and unfortunately had to turn around before getting any closer. This is what it looked like outside. We still had clear skies for the most part. Honeywell had changed the engines on the Convair for C-130 turboprop engines, which are better able to fly through storms when needed.
