Procedure The aircraft on the offset course approach must see the runway-landing environment and, if ATC
has advised that traffic on the straight-in approach is a factor, the offset course approach aircraft
must visually acquire the straight-in approach aircraft and report it in sight to ATC prior to reach-
ing the DA for the offset course approach.
CC The Clear of Clouds point is the position on the offset final approach course where aircraft
first operate in visual meteorological conditions below the ceiling, when the actual weather
conditions are at, or near, the minimum ceiling for SOIA operations. Ceiling is defined by the
Aeronautical Information Manual.

d. Attention All Users Page (AAUP). Multiple
PRM approach charts at the same airport have a single
AAUP associated with them that must be referred to
in preparation for conducting the approach.
Bullet points are published which summarize the
PRM procedures which apply to each approach and
must be briefed before conducting a PRM approach.
The following information may be summarized in the
bullet points or published in more detail in the Expan-
ded Procedures section of the AAUP. Briefing on the
Expanded Procedures is optional.

1. 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 ap-
proach. If later advised to expect the ILS or LDA
approach (should one be published), the ILS PRM or
LDA PRM chart may be used after completing the
following briefing items. The pilot may also request
to fly the RNAV (GPS) PRM in lieu of either the ILS
PRM or LDAPRM approach. In the event of the loss
of ground based NAVAIDS, the ATIS may advertise
RNAV (GPS) PRM approaches to the effected run-
way or runways.

(a) Minimums and missed approach proced-
ures are unchanged.
(b) PRM Monitor frequency no longer re-

(c) ATC may assign a lower altitude for glide
slope intercept.
In the case of the LDA PRM approach, this briefing proced-
ure only applies if an LDA-DME approach is also


In the case of the SOIA ILS PRM and LDA PRM pro-
cedure, the AAUP describes the weather conditions
in which simultaneous approaches are authorized:

Simultaneous approach weather minimums are
X,XXX feet (ceiling), x miles (visibility).
2. Dual VHF Communications Required.
To avoid blocked transmissions, each runway will
have two frequencies, a primary and a PRM monitor
frequency. The tower controller will transmit on both
frequencies. The monitor controller's transmissions,
if needed, will override both frequencies. Pilots will
ONLY transmit on the tower controller's frequency,
but will listen to both frequencies. Select the PRM
monitor frequency audio only when instructed by
ATC to contact the tower. The volume levels should
be set about the same on both radios so that the pilots
will be able to hear transmissions on at least one fre-
quency if the other is blocked. Site specific
procedures take precedence over the general informa-
tion presented in this paragraph. Refer to the AAUP
for applicable procedures at specific airports.
At SFO, pilots conducting SOIA operations select the mon-
itor frequency audio when communicating with the final
radar controller. In this special case, the monitor control-
ler's transmissions, if required, override the final
controller's frequency.
3. Breakouts. Breakouts differ from other types
of abandoned approaches in that they can happen
anywhere and unexpectedly. Pilots directed by ATC
to break off an approach must assume that an aircraft
is blundering toward them and a breakout must be ini-
tiated immediately.
(a) Hand-fly breakouts. All breakouts are
to be hand-flown to ensure the maneuver is accom-
plished in the shortest amount of time.
(b) ATC Directed "Breakouts." ATC dir-
ected breakouts will consist of a turn and a climb or

descent. Pilots must always initiate the breakout in re-

sponse to an air traffic controller's instruction.
Controllers will give a descending breakout only
when there are no other reasonable options available,
but in no case will the descent be below the minimum
