3200’ ALTITUDE INTERCEPTS GLIDE SLOPE.
RADAR MONITORING PROVIDED TO ENSURE SEPARATION
BETWEEN AIRCRAFT ON PARALLEL LOCALIZERS. WHEN GLIDE
SLOPE INOPERATIVE BEGIN DESCENT AT MEADOW INTERSECTION.
(RUNWAY CENTERLINES SPACED 4300’ OR MORE [DUAL RUNWAYS]
OR 5000’ OR MORE, [TRIPLE OR QUADRUPLE RUNWAYS] - RADAR MONITORING REQUIRED)
a. System. An approach system permitting
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.
b. 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:
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.
2. The final monitor controller will have the
capability of overriding the tower controller on the
tower frequency.
3. Pilots will be instructed to monitor the tower
frequency to receive advisories and instructions.
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.”
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).”
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.

(a) An approach system that permits
simultaneous ILS/PRM approaches to dual runways
with centerlines separated by less than 4,300 feet but
at least 3,400 feet for parallel approach courses, and
at least 3,000 feet if one ILS if offset by 2.5 to
