a missed approach, the remainder of the procedure
coding is standard and can be utilized as with any oth-
er IAP.

b. Simultaneous Offset Instrument Approach
(SOIA).
1. SOIA is an acronym for Simultaneous Offset
Instrument Approach, a procedure used to conduct
simultaneous approaches to runways spaced less than
3,000 feet, but at least 750 feet apart. The SOIA pro-
cedure utilizes an ILS PRM approach to one runway
and an offset Localizer Type Directional Aid (LDA)
PRM approach with glide slope to the adjacent run-
way. In SOIA operations, aircraft are paired, with the
aircraft conducting the ILS PRM approach always
positioned slightly ahead of the aircraft conducting
the LDA PRM approach.

2. The ILS PRM approach plates used in SOIA

operations are identical to other ILS PRM approach

plates, with an additional note, which provides the

separation between the two runways used for simul-
taneous approaches. The LDA PRM approach plate
displays the required notations for closely spaced ap-
proaches as well as depicting the visual segment of
the approach.

3. Controllers monitor the SOIA ILS PRM and
LDA PRM approaches in exactly the same manner as
is done for ILS PRM approaches. The procedures and
system requirements for SOIA ILS PRM and LDA
PRM approaches are identical with those used for
simultaneous close parallel ILS PRM approaches un-
til near the LDA PRM approach missed approach
point (MAP) -- where visual acquisition of the ILS
aircraft by the aircraft conducting the LDA PRM ap-
proach occurs. Since the ILS PRM and LDA PRM
approaches are identical except for the visual segment
in the SOIA concept, an understanding of the proced-
ures for conducting ILS PRM approaches is essential
before conducting a SOIA ILS PRM or LDA PRM
operation.

4. In SOIA, the approach course separation (in-

stead of the runway separation) meets established

close parallel approach criteria. Refer to
FIG 5-4-23 for the generic SOIA approach geo-
metry. 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 run-
way centerline. 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 leading ILS aircraft prior to the LDA air-
craft reaching the LDA MAP. If visual acquisition is
not accomplished, a missed approach must be ex-
ecuted at the LDA MAP.
c. Requirements and Procedures.

Besides system requirements and pilot procedures as
identified in subparagraph a1 above, all pilots must
have completed special training before accepting a
clearance to conduct ILS PRM or LDA PRM Simul-
taneous 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-ap-
proved company training as identified in their
Operations Specifications. Training, at a minim-
um, must require pilots to view the FAA video
"ILS PRM AND SOIA APPROACHES: INFORM-
ATION FOR AIR CARRIER PILOTS." Refer to
https://www.faa.gov/training_testing/training/
prm/ or search key words FAA PRM for
additional information and to view or download the
video.

(b) For operations under Part 91:
(1) Pilots operating transport category
aircraft must be familiar with PRM operations as con-
tained in this section of the AIM. In addition, pilots
operating transport category aircraft must view
the FAA video "ILS PRM AND SOIA
APPROACHES: INFORMATION FOR AIR
CARRIER PILOTS." Refer to https://www.faa.gov/
training_testing/training/prm/ or search key

words FAA 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-
