A new 3-D radar system developed by Honeywell for planes allows pilots to get a better picture of severe weather. It’s able to detect turbulence, hail and lightning and warn pilots ahead of flying through them. Currently about 2,000 planes with more than 70 airlines worldwide are outfitted with the system, with about 2,500 more on order, according to Honeywell.

TRADITIONAL RADAR

In a conventional system, the pilot must manually tilt the radar up and down to scan a particular part of the sky. The scan only shows a narrow slice of what is in front of the plane, potentially missing storms above or below the scan, or getting interference off the ground.


NEW 3-D RADAR

The system, called IntuVue 3-D, automatically pans up and down using an algorithm to filter out interference and creates a continuous 3-D image of conditions ahead of the aircraft, much like ground-based radar. The sytem can scan from ground level to 60,000 feet and out to 320 nautical miles ahead of the aircraft, providing up to a 10-minute head start to avoid severe weather.
