SITING OF TARGET SIMULATORS. (CONT)
METHOD ONE (CONT)
305NE216
1.
Determine clr (1) by measuring width of runway and dividing by two.
2.
Determine and record radar offset from clr distance (A) by measuring a straight line, perpendicular to clr (1), to
center of radar set group (2).
3.
Determine and record distance to td (B) by measuring a straight line from radar set group (2) to td point (3). This
distance will be used in future cursor alinements (para 4-28).
4.
Extend a straight line, at least 75 feet (22.9 m) long, from td point (3) away from radar set group side of runway
and perpendicular to clr (1). Record this distance (C), and position first td bracketing target reflector (4) at this
point.
5.
Extend a straight line from td point (3) toward radar set group side of runway and perpendicular to clr (1), that is
the same distance (distance C) as that recorded in step 4. Position second td bracketing reflector (5) at this
point.
6.
Select a point on clr (1) approximately 150 feet (45.8 m) in from td point (3) (this distance is not critical).
Measure a straight line perpendicular to clr (1) through this point that is the same distance (dotted line A) as that
recorded in step 2. Position rpl target reflector (6) at this point.
METHOD TWO
TOOLS REQUIRED:
Measuring tape
PERSONNEL REQUIRED: Two
This method uses two target simulators for each runway approach, as opposed to method one, which uses three target
reflectors for each approach. One target reflector is positioned at some point on clr beyond td point. The other reflector
is positioned on rpl at a point that equals the distance between radar set group and td point.
