IntuVue RDR-4000 Weather Radar Pilot's Guide
ADVISORY ALERTS
 The Advisory Alert region is ±40° from the aircraft track and from
0.5 nm to 5.0 nm in front of the aircraft.
 Between 50 ft and 1,500 ft AGL the system indicates ADVISORY
Alerts by overlaying the windshear icon(s) on the radar display. New
Advisory Alerts are inhibited below 50 ft AGL if airspeed is greater
than 100 kts on takeoff, or greater than 60 kts on approach.
CAUTION ALERTS
 The Caution Alert region is ±25° from the aircraft track and from
0.5 nm to 3.0 nm in front of the aircraft.
 Between 50 ft and 1,200 ft AGL the system indicates CAUTION
Alerts with visual and aural annunciations in addition to displaying the
windshear icon(s). New Caution Alerts are inhibited below 50 ft AGL
if airspeed is greater than 100 kts on takeoff, or greater than 60 kts
on approach.
WARNING ALERTS
 The WARNING Alert region is ±0.25 nm either side of the aircraft
track and from 0.5 nm to 1.5 nm (3.0 nm on the ground) in front of the
aircraft. On approach below 370 ft, warnings beyond the far end of
the runway are inhibited.
 Between 50 ft and 1,200 ft AGL the system indicates WARNING
Alerts with visual and aural annunciations in addition to displaying the
windshear icon(s). New Warning Alerts are inhibited below 50 ft AGL
if airspeed is greater than 100 kts on takeoff, or greater than 60 kts
on approach.
WINDSHEAR ALERT INHIBIT REGIONS
The following table summarizes the PWS Inhibit Regions.
Advisory Alerts are Enabled below 1,500 ft.
Caution and Warning Alerts are Enabled below 1,200 ft.
On Takeoff, All New Alerts are INHIBITED when airspeed is greater
than 100 kts if radio altitude is less than 50 ft AGL.
On Approach, All New Alerts are INHIBITED when airspeed is greater
than 60 kts if radio altitude is less than 50 ft AGL.
