runways are in use. In addition, the radar controller
will have the interphone capability of communicating
with the tower controller where separation responsibility
has not been delegated to the tower.

19.1 System. This approach system permits simultaneous
ILS/MLS approaches to parallel runways
with centerlines separated by 4,300 to 9,000 feet, and
equipped with final monitor controllers. Simultaneous
parallel ILS/MLS approaches require radar
monitoring to ensure separation between aircraft on
the adjacent parallel approach course. Aircraft
position is tracked by final monitor controllers who
will issue instructions to aircraft observed deviating
from the assigned localizer course. Staggered radar
separation procedures are not utilized. Integral parts
of a total system are ILS/MLS, radar, communications,
ATC procedures, and required airborne
equipment. The Approach Procedure Chart permitting
simultaneous parallel ILS/MLS approaches will
contain the note “simultaneous approaches authorized
RWYS 14L and 14R,” identifying the
appropriate runways as the case may be. When
advised that simultaneous parallel ILS/MLS approaches
are in progress, pilots shall advise approach
control immediately of malfunctioning or inoperative
receivers, or if a simultaneous parallel ILS/MLS
approach is not desired.

19.2 Radar Monitoring. This service is provided
for each simultaneous parallel ILS/MLS approach to
ensure aircraft do not deviate from the final approach
course. Radar monitoring includes instructions if an
aircraft nears or penetrates the prescribed NTZ (an
area 2,000 feet wide located equidistant between
parallel final approach courses). This service will be
provided as follows:
19.2.1 During turn on to parallel final approach,
aircraft will be provided 3 miles radar separation or
a minimum or 1,000 feet vertical separation. The
assigned altitude must be maintained until intercepting
the glide path, unless cleared otherwise by ATC.
Aircraft will not be vectored to intercept the final
approach course at an angle greater than thirty
degrees.
19.2.2 The final monitor controller will have the
capability of overriding the tower controller on the
tower frequency.
19.2.3 Pilots will be instructed to monitor the tower
frequency to receive advisories and instructions.
19.2.4 Aircraft observed to overshoot the turn−on or
to continue on a track which will penetrate the NTZ
will be instructed to return to the correct final
approach course immediately. The final monitor
controller may also issue missed approach or
breakout instructions to the deviating aircraft.
PHRASEOLOGY−
“(Aircraft call sign) YOU HAVE CROSSED THE FINAL
APPROACH COURSE. TURN (left/right) IMMEDIATELY
AND RETURN TO THE LOCALIZER/AZIMUTH
COURSE.”
or
“(Aircraft call sign) TURN (left/right) AND RETURN TO
THE LOCALIZER/AZIMUTH COURSE.”
19.2.5 If a deviating aircraft fails to respond to such
instructions or is observed penetrating the NTZ, the
aircraft on the adjacent final approach course may be
instructed to alter course.
PHRASEOLOGY−
“TRAFFIC ALERT (aircraft call sign) TURN (left/right)
IMMEDIATELY HEADING (degrees), (climb/descend)
AND MAINTAIN (altitude).”
19.2.6 Radar monitoring will automatically be
terminated when visual separation is applied, the
aircraft reports the approach lights or runway in sight,
or the aircraft is 1 mile or less from the runway
threshold (for runway centerlines spaced 4,300 feet
or greater). Final monitor controllers will not advise
pilots when radar monitoring is terminated.
