and is where the NTZ terminates. Maneuvering inside the MAP is done in visual conditions.
Angle Angle formed at the intersection of the extended LDA runway centerline and a line drawn between
the LDA MAP and the SAP. The size of the angle is determined by the FAA SOIA computer design
program, and is dependent on whether Heavy aircraft use the LDA and the spacing between the
runways.
Visibility Distance from MAP to runway threshold in statute miles (light credit applies).
Procedure LDA aircraft must see the runway landing environment and, if less than standard radar
separation exists between the aircraft on the adjacent ILS course, the LDA aircraft must visually
acquire the ILS aircraft and report it in sight to ATC prior to the LDA MAP.
CC Clear Clouds.
(2) Pilots not operating transport category
aircraft must be familiar with PRM and SOIA
operations as contained in this section of the AIM.
The FAA strongly recommends that pilots not
involved in transport category aircraft operations
view the FAA video, “ILS PRM AND SOIA
APPROACHES: INFORMATION FOR GENERAL
AVIATION PILOTS.” Refer to http://www.faa.gov/
AVR/AFS/PRMtraining/ for additional information
and to view or download the video.
2. ATC Directed Breakout. An ATC directed
“breakout” is defined as a vector off the ILS or LDA
approach course in response to another aircraft
penetrating the NTZ, the 2,000 foot wide area located
equidistance between the two approach courses that
is monitored by the PRM monitor controllers.
3. Dual Communications. The aircraft flying
the ILS/PRM or LDA/PRM approach must have the
capability of enabling the pilot/s to listen to two
communications frequencies simultaneously.
AIM 2/17/05
5−4−38 Arrival Procedures
c. Radar Monitoring. Simultaneous close parallel
ILS/PRM and LDA/PRM approaches require that
final monitor controllers utilize the PRM system to
ensure prescribed separation standards are met.
Procedures and communications phraseology are
also described in paragraph 5−4−15, Simultaneous
Parallel ILS/MLS Approaches (Independent). A
minimum of 3 miles radar separation or 1,000 feet
vertical separation will be provided during the
turn−on to close parallel final approach courses. To
ensure separation is maintained, and in order to avoid
an imminent situation during simultaneous close
parallel ILS/PRM or SOIA ILS/PRM and LDA/PRM
approaches, pilots must immediately comply with
PRM monitor controller instructions. In the event of
a missed approach, radar monitoring is provided to
one−half mile beyond the most distant of the two
runway departure ends for ILS/RPM approaches. In
SOIA, PRM radar monitoring terminates at the LDA
MAP. Final monitor controllers will not notify pilots
when radar monitoring is terminated.
d. Attention All Users Page (AAUP). ILS/PRM
and LDA/PRM approach charts have an AAUP
associated with them that must be referred to in
preparation for conducting the approach. This page
contains the following instructions that must be
followed if the pilot is unable to accept an ILS/PRM
or LDA/PRM approach.
1. At airports that conduct PRM operations,
(ILS/PRM or, in the case of airports where SOIAs are
conducted, ILS/PRM and LDA/PRM approaches)
pilots not qualified to except PRM approaches must
contact the FAA Command Center prior to departure
(1−800−333−4286) to obtain an arrival reservation
(see FAA Advisory Circular 90−98, Simultaneous
Closely Spaced Parallel Operations at Airports Using
Precision Runway Monitor (PRM) Systems). Arriving
flights that are unable to participate in ILS/PRM
or LDA/PRM approaches and have not received an
arrival reservation are subject to diversion to another
airport or delays. Pilots en route to a PRM airport
designated as an alternate, unable to reach their filed
destination, and who are not qualified to participate
in ILS/PRM or LDA/PRM approaches must advise
ATC as soon as practical that they are unable to
participate. Pilots who are qualified to participate but
experience an en route equipment failure that would
preclude participation in PRM approaches should
notify ATC as soon as practical.
2. The AAUP covers the following operational
topics:
(a) ATIS. When the ATIS broadcast advises
ILS/PRM approaches are in progress (or ILS PRM
and LDA PRM approaches in the case of SOIA),
pilots should brief to fly the ILS/PRM or LDA/PRM
approach. If later advised to expect the ILS or LDA
approach (should one be published), the ILS/PRM or
