FIG 5-9-8
Parallel Dependent ILS/MLS Approaches
EXAMPLEIn
FIG 5-9-8, Aircraft 2 is 2 miles from heavy Aircraft 1.
Aircraft 3 is a small aircraft and is 6 miles from Aircraft1.
*The resultant separation between Aircrafts 2 and 3 is
4.2miles.
4. Provide the minimum applicable radar
separation between aircraft on the same final
approach course.
REFERENCEFAAO
JO 7110.65, Section 5, Radar Separation, Para 5-5-4, Minima.
b. The following conditions are required when
applying the minimum radar separation on adjacent
localizer/azimuth courses allowed in subpara a:
1. Apply this separation standard only after
aircraft are established on the parallel final approach
course.
2. Straight‐in landings will be made.
3. Missed approach procedures do not conflict.
4. Aircraft are informed that approaches to both
runways are in use. This information may be provided
through the ATIS.
5. Approach control shall have the interphone
capability of communicating directly with the local
controller at locations where separation responsibility
has not been delegated to the tower.
NOTEThe
interphone capability is an integral part of this
procedure when approach control has the sole separation
responsibility.

by Towers.
c. Consideration should be given to known factors
that may in any way affect the safety of the instrument
approach phase of flight, such as surface wind
direction and velocity, wind shear alerts/reports,
severe weather activity, etc. Closely monitor weather
activity that could impact the final approach course.
Weather conditions in the vicinity of the final
approach course may dictate a change of approach in
use.

5-9-7. SIMULTANEOUS INDEPENDENT
ILS/MLS APPROACHES- DUAL & TRIPLE
TERMINAL
a. Apply the following minimum separation when
conducting simultaneous independent ILS, MLS, or
ILS and MLS approaches:
1. Provide a minimum of 1,000 feet vertical or
a minimum of 3 miles radar separation between
aircraft during turn‐on to parallel final approach.
NOTE-
1. During triple parallel approaches, no two aircraft will
be assigned the same altitude during turn‐on. All
threeaircraft will be assigned altitudes which differ by a
minimum of 1,000 feet. Example: 3,000, 4,000, 5,000;
7,000, 8,000, 9,000.
2. Communications transfer to the tower controller's
frequency shall be completed prior to losing vertical
separation between aircraft.
2. Dual parallel runway centerlines are at least
4,300 feet apart.
3. Triple parallel runway centerlines are at least
5,000 feet apart and the airport field elevation is less
than 1,000 feet MSL.
4. A high‐resolution color monitor with alert
algorithms, such as the final monitor aid or that
required in the precision runway monitor program
shall be used to monitor approaches where:
(a) Triple parallel runway centerlines are at
least 4,300 but less than 5,000 feet apart and the
airport field elevation is less than 1,000 feet MSL.
(b) Triple parallel approaches to airports
where the airport field elevation is 1,000 feet MSL or
more require the high resolution color monitor with
alert algorithms and an approved FAA aeronautical
study.
5. Provide the minimum applicable radar
separation between aircraft on the same final
approach course.
REFERENCEFAAO
JO 7110.65, Para 5-5-4, Minima.
b. The following conditions are required when
applying the minimum separation on adjacent dual or
triple ILS/MLS courses allowed in subpara a:
1. Straight‐in landings will be made.
2. ILS, MLS, radar, and appropriate frequencies
are operating normally.
3. Inform aircraft that simultaneous ILS/MLS
approaches are in use prior to aircraft departing an
outer fix. This information may be provided through
the ATIS.
4. Clear the aircraft to descend to the
appropriate glideslope/glidepath intercept altitude
soon enough to provide a period of level flight to
dissipate excess speed. Provide at least 1 mile of
straight flight prior to the final approach course
intercept.

applicable to curved and segmented MLS approaches.
5. An NTZ at least 2,000 feet wide is established
