GROUND CONTROL MUST NOTIFY LOCAL CONTROL

WHEN A DEPARTING A/C HAS BEEN TAXIED TO A RUNWAY OTHER THAN THE ONE PREVIOUSLY DESIGNATED AS ACTIVE

GROUND CONTROL MUST NOTIFY LOCAL CONTROL OF ANY

"PROCEED AS REQUESTED" IS NOT APPROVED PHRASEOLOGY

FOR INSTRUCTING A/C, VEHICLES, EQUIPMENT, OR PERSONNEL TO CROSS OR OPERATE ON A RUNWAY

DESCRIBE VEHICLES, EQUIPMENT, OR PERSONNEL ON OR NEAR THE MOVEMENT AREA

IN A MANNER IN WHICH IT WILL ASSIST PILOTS IN RECOGNIZING THEM

WHEN LOW LEVEL WIND SHEAR/MICROBURST IS REPORTED BY PILOTS

CONTROLLERS MUST ISSUE THE ALERT TO ALL ARRIVING AND DEPARTING A/C

CONTINUE THE ALERT TO A/C UNTIL IT IS BROADCAST ON THE ATIS AND PILOTS INDICATE THEY HAVE RECEIVED THE APPROPRIATE ATIS CODE

A STATEMENT MUST BE INCLUDED ON THE ATIS FOR 20 MINUTES FOLLOWING THE LAST REPORT OR INDICATION OF THE WIND SHEAR/MICROBUSRT

PREDICTIVE WIND SHEAR (PWS) ALERT SYSTEMS THAT WARN THE FLIGHT CREW OF A POTENTIAL WIND SHEAR UP TO

3 MILES AHEAD AND 25 DEGREES EITHER SIDE OF THE A/C HEADING AT OR BELOW 1200' AGL

AT FACILITIES WITHOUT ATIS

ENSURE THAT WIND SHEAR/MICROBURST INFORMATION IS BROADCAST TO ALL ARRIVING AND DEPARTING A/C FOR 20 MINUTES FOLLOWING THE LAST REPORT OR INDICATION OF THE WIND SHEAR/MICROBUSRT

AT LOCATIONS EQUIPPED WITH LLWAS, THE LOCAL CONTROLLER MUST PROVIDE WIND INFORMATION AS FOLLOWS:

a. IF AN ALERT IS RECEIVED, ISSUE THE AIRPORT WIND AND THE DISPLAYED FIELD BOUNDARY WIND

b. IF MULTIPLE ALERTS ARE RECEIVED, ISSUE AN ADVISORY THAT THERE ARE WIND SHEAR ALERTS IN TWO/SEVERAL/ALL QUADRANTS.

c. IF REQUESTED BY THE PILOT, ISSUE SPECIFIC FIELD BOUNDARY WIND INFORMATION EVEN THOUGH THE LLWAS MAY NOT BE IN ALERT STATUS

WIND SHEAR DETECTION SYSTEMS, PROVIDE THE CAPABILITY OF DISPLAYING MICROBURST ALERTS, WIND SHEAR ALERTS, AND WIND INFORMATION ORIENTED TO THE THRESHOLD OR DEPARTURE END OF A RUNWAY

WHEN DETECTED, THE ASSOCIATED RIBBON DISPLAY ALLOWS THE CONTROLLER TO READ THE DISPLAYED ALERT WITHOUT ANY NEED FOR INTERPRETATION

IF A WIND SHEAR OR MICROBURST ALERT IS RECEIVED FOR THE RUNWAY IN USE

ISSUE THE ALERT INFORMATION FOR THAT RUNWAY TO ARRIVING AND DEPARTING A/C AS IT IS DISPLAYED ON THE RIBBON DISPLAY

LLWAS NE++ OR LLWAS -RS MAY DETECT A POSSIBLE WIND SHEAR/MICROBURST AT THE EDGE OF THE SYSTEM

BUT MAY BE UNABLE TO DISTINGUISH BETWEEN A WIND SHEAR AND A MICROBURST.

IF UNSTABLE CONDITIONS PRODUCE MULTIPLE ALERTS

ISSUE AN ADVISORY OF MULTIPLE WIND SHEAR/MICROBURST ALERTS FOLLOWED BY SPECIFIC ALERT OR WIND INFORMATION MOST APPROPRIATE TO THE A/C OPERARION

LLWAS NE++ AND LLWAS -RS ARE DESIGNED TO OPERATE WITH AS MANY AS 50 PERCENT OF THE TOTAL SENSORS INOPERATIVE

WHEN ALL 3 REMOTE SENSORS DESIGNATED FOR A SPECIFIC RUNWAY ARE INOPERATIVE THEN IT MUST BE CONSIDERED OUT OF SERVICE
