Simultaneous Parallel ILS/RNAV/GLS Approaches

a. System.

An approach system permitting

simultaneous ILS/RNAV/GLS approaches to parallel

runways with centerlines separated by 4,300 to

9,000 feet, and equipped with final monitor

controllers. Simultaneous parallel 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 ILS, radar,

communications, ATC procedures, and required

airborne equipment. The Approach Procedure Chart

permitting simultaneous approaches will contain a

note identifying the other runways or approaches that

may be used simultaneously. When advised that

simultaneous approaches are in progress, pilots must

advise approach control immediately of

malfunctioning or inoperative receivers, or if a

simultaneous approach is not desired.

b. NTZ Radar Monitoring.

This service is

provided for each simultaneous 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 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.
