This display in the research cockpit of Langley's 737 aircraft is flashing the location and intensity of two microbursts two to three miles ahead. The plane's position is at the bottom of the cone. One of the microbursts measures 0.09, just shy of what is considered a hazard (0.105). The other, at 0.14, is a confirmed hazard.
