Simultaneous Independent ILS/RNAV/GLS Approaches

a. System.

An approach system permitting si-

multaneous approaches to parallel runways with
centerlines separated by at least 4,300 feet.
Separation between 4,300 and 9,000 feet (9,200’ for
airports above 5,000’) utilizing NTZ final monitor
controllers. Simultaneous independent approaches
require NTZ 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 final approach
course. Staggered radar separation procedures are not
utilized. Integral parts of a total system are radar,
communications, ATC procedures, and ILS or other
required airborne equipment. A chart note identifies
that the approach is authorized for simultaneous use.

When simultaneous operations are in use, it will be

advertised on the ATIS. When advised that simulta-
neous approaches are in use, pilots must advise
approach control immediately of malfunctioning or
inoperative receivers, or if a simultaneous approach
is not desired. Although non

−precision minimums

may be published, pilots must only use those proce-
dures specifically authorized by chart note. For
example, the chart note “LNAV NA during simulta-
neous operations,” requires vertical guidance. When
given a choice, pilots should always fly a precision
approach whenever possible.

NOTE

ATC does not use the word independent or parallel when
advertising these operations on the ATIS.

EXAMPLE

Simultaneous ILS Runway 24 left and ILS Runway 24 right
approaches in use.
