Arrival Procedures

ition of the ILS aircraft by the aircraft conducting the

LDA PRM approach occurs. Since the ILS PRM and

LDA PRM approaches are identical except for the

visual segment in the SOIA concept, an understand-

ing of the procedures for conducting ILS PRM

approaches is essential before conducting a SOIA

ILS PRM or LDA PRM operation.

(d)

In SOIA, the approach course separation

(instead of the runway separation) meets established

close parallel approach criteria. Refer to FIG 5−4−23

for the generic SOIA approach geometry. A visual

segment of the LDA PRM approach is established

between the LDA MAP and the runway threshold.

Aircraft transition in visual conditions from the LDA

course, beginning at the LDA MAP, to align with the

runway and can be stabilized by 500 feet above

ground level (AGL) on the extended runway center-

line. Aircraft will be “paired” in SOIA operations,

with the ILS aircraft ahead of the LDA aircraft prior

to the LDA aircraft reaching the LDA MAP. A cloud

ceiling for the approach is established so that the LDA

aircraft has nominally 30 seconds to acquire the lead-

ing ILS aircraft prior to the LDA aircraft reaching the

LDA MAP. If visual acquisition is not accomplished,

a missed approach must be executed at the LDA

MAP.

b. Requirements.

Besides system requirements as identified in sub−

paragraph a, above, all pilots must have completed

special training before accepting a clearance to con-

duct ILS PRM or LDA PRM Simultaneous Close

Parallel Approaches.

1. Pilot Training Requirement.

Pilots must

complete special pilot training, as outlined below,

before accepting a clearance for a simultaneous close

parallel ILS PRM or LDA PRM approach.

(a)

For operations under 14 CFR Parts 121,

129, and 135 pilots must comply with FAA approved

company training as identified in their Operations

Specifications. Training, at a minimum, must

require pilots to view the FAA video “ILS PRM AND

SOIA APPROACHES: INFORMATION FOR AIR

CARRIER PILOTS.” Refer to http://www.faa.gov/
training_testing/training/prm/ 

for additional

information and to view or download the video.

(b)

For operations under Part 91:

(1)

Pilots operating 

transport cat-

egory 

aircraft must be familiar with PRM operations

as contained in this section of the AIM. In

addition, pilots operating transport category air-
craft 

must view the FAA video “ILS PRM AND

SOIA APPROACHES: INFORMATION FOR AIR

CARRIER PILOTS.” Refer to http://www.faa.gov/
training_testing/training/prm/ 

for additional

information and to view or download the video.

(2)

Pilots not operating transport cat-

egory 

aircraft must be familiar with PRM and SOIA

operations as contained in this section of the AIM.

The FAA strongly recommends that pilots not in-

volved in transport category aircraft operations

view the FAA video, “ILS PRM AND SOIA AP-

PROACHES: INFORMATION FOR GENERAL

AVIATION PILOTS.” Refer to http://www.faa.gov/
training_testing/training/prm/ 

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 penet-

rating 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 com-

munications frequencies simultaneously.

c. Radar Monitoring.

Simultaneous close

parallel ILS PRM and LDA PRM approaches require

that final monitor controllers utilize the PRM system

when runways (or in the case of SOIA, the final

approach course separation) are spaced less than

3,600 feet but at least 3,000 feet apart to ensure pre-

scribed separation standards are met. Procedures and

communications phraseology are also described in

Paragraph 5−4−15, Simultaneous Parallel ILS/

RNAV/GLS Approaches (Independent). A minimum

of 3 miles radar separation or 1,000 feet vertical sep-

aration 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 situ-

ation during simultaneous close parallel ILS PRM or

SOIA ILS PRM and LDA PRM approaches, pilots

must immediately comply with PRM monitor con-

troller instructions. In the event of a missed approach,

radar monitoring is provided to one-half mile beyond

the more distant of the two runway departure ends for

ILS PRM approaches. In SOIA, PRM radar monitor-
