FIG 5-4-20
Simultaneous (Parallel) Dependent Approaches
a. Simultaneous (parallel) dependent approaches
are an ATC procedure permitting approaches to
airports having parallel runway centerlines separated
by between 2,500 feet and 9,000 feet. Integral parts
of a total system are ILS, radar, communications,
ATC procedures, and required airborne equipment.
RNAV equipment in the aircraft or GLS equipment
on the ground and in the aircraft may replace the
required airborne and ground based ILS equipment.
b. A simultaneous (parallel) dependent approach
differs from a simultaneous (parallel) independent
approach in that, the minimum distance between
parallel runway centerlines is reduced; there is no
requirement for radar monitoring or advisories; and
a staggered separation of aircraft on the adjacent final
course is required.
c. A minimum of 1.0 NM radar separation
(diagonal) is required between successive aircraft on
the adjacent final approach course when runway
centerlines are at least 2,500 feet but no more than
3,600 feet apart. A minimum of 1.5 NM radar
separation (diagonal) is required between successive
aircraft on the adjacent final approach course when
runway centerlines are more than 3,600 feet but no
more than 8,300 feet apart. When runway centerlines
are more than 8,300 feet but no more than 9,000 feet
apart a minimum of 2 NM diagonal radar separation
is provided. Aircraft on the same final approach
course within 10 NM of the runway end are provided
a minimum of 3 NM radar separation, reduced to
2.5 NM in certain circumstances. In addition, a
minimum of 1,000 feet vertical or a minimum of three
miles radar separation is provided between aircraft
during turn on to the parallel final approach course.
d. Whenever parallel approaches are in progress,
pilots are informed by ATC or via the ATIS that
approaches to both runways are in use. The charted
IAP also notes which runways may be used
simultaneously. 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.
