DETERMINING ELEVATION CURSOR ALINEMENT ANGLE
Elevation cursor alinement angle (B) is an angle from radar set group to aircraft when aircraft is 5 miles plus distance D
(distance from radar set group to td point) from td point. Because radar set group is located 400 feet (122 m) or more
down runway from td point, elevation cursor alinement angle will always be less than glidepath angle (C). To calculate
elevation cursor alinement angle, the elevation 5mile intercept angle (A) must first be determined. Find elevation cursor
alinement angle for each runway approach as follows.
