5-4-13. Simultaneous Approaches to
Parallel Runways
FIG 5-4-20

Simultaneous Approaches
(Approach Courses Parallel and Offset between 2.5 and 3.0 degrees)

a. ATC procedures permit ILS/RNAV/GLS
instrument approach operations to dual or triple
parallel runway configurations. ILS/RNAV/GLS
approaches to parallel runways are grouped into three
classes: Simultaneous Dependent Approaches; Sim
ultaneous Independent Approaches; and
Simultaneous Close Parallel PRM Approaches.
RNAV approach procedures that are approved for
simultaneous operations require GPS as the sensor
for position updating. VOR/DME, DME/DME and

Arrival Procedures

IRU RNAV updating is not authorized. The
classification of a parallel runway approach
procedure is dependent on adjacent parallel runway
centerline separation, ATC procedures, and airport
ATC final approach radar monitoring and commu
nications capabilities. At some airports, one or more
approach courses may be offset up to 3 degrees. ILS
approaches with offset localizer configurations result
in loss of Category II/III capabilities and an increase
in decision altitude/height (50").
