b. ICAO Doc 4444, Chapter 15, In-flight
Contingency Procedures.
Doc 4444 Chapter 15
contains important guidance for pilot training
programs. For ease of reference, significant Chapter
15 paragraphs are posted on the Gulf of Mexico 50
NM Lateral Separation Web Page. Chapter 15
paragraphs posted on the website include:
1.
Paragraph 15.2 (Special Procedures for
In-Flight Contingencies in Oceanic Airspace).
Paragraph 15.2.2 (General Procedures) provides
guidance for in-flight diversions, turn-backs and for
loss of, or significant reduction in, required
navigation capability when operating in an airspace
where the navigation performance accuracy is a
prerequisite to the safe conduct of flight operations.
2.
Paragraph 15.2.3 (Weather Deviation Pro-
cedures). Paragraph 15.2.3 provides guidance for
events where the pilot is able to obtain a clearance
prior to deviating from track to avoid convective
weather and for events where the pilot is unable to
obtain clearance prior to deviating.
c. Strategic Lateral Offset Procedures (SLOP).
Pilots should use SLOP procedures in the course of
regular oceanic operations. SLOP procedures are
published in ICAO Document 4444, 15th Edition,
Amendment 2, paragraph 16.5 and FAA Notices.
They are posted on the Gulf of Mexico 50 NM Lateral
Separation Web Page and are addressed in the RNP
10 and RNP 4 Job Aids.
d. Pilot Report of NonRNP10 Status.
The pilot
must report the lack of RNP 10 or RNP 4 status in
accordance with the following:
1.
When the operator/aircraft is not authorized
RNP 10 or RNP 4. See paragraph 4−7−5.
2.
If approval status is requested by the
controller in accordance with paragraph 4−7−9e.
e. Pilot Statement of RNP 10 or RNP 4
Approval Status, If Requested.
If requested by the
controller, the pilot must communicate approval
status using the following phraseology:
Controller Request:
(Call sign) confirm RNP 10 or 4 approved
Pilot Response:
“Affirm RNP 10 approved” or “Affirm RNP 4
approved,” as appropriate, or
“Negative RNP 10” (See paragraph 4−7−5 for
NonRNP10 aircraft procedures.)
f. Pilot action when navigation system mal-
functions.
In addition to the actions suggested in
ICAO Doc. 4444, Chapter 15, when pilots suspect a
navigation system malfunction, the following actions
should be taken:
1.
Immediately inform ATC of navigation
system malfunction or failure.
2.
Accounting for wind drift, fly magnetic
compass heading to maintain track.
3.
Request radar vectors from ATC, when
available
