Chapter 8. Offshore/Oceanic Procedures
Section 1. General
8-1-1. ATC SERVICE
Provide air traffic control service in oceanic
controlled airspace in accordance with the procedures
in this chapter except when other procedures/minima
are prescribed in a directive or a letter of agreement.
REFERENCE-
FAAO JO 7110.65, Procedural Letters of Agreement, Para
1-1-9.
8-1-2. OPERATIONS IN OFFSHORE
AIRSPACE AREAS
Provide air traffic control service in offshore airspace
areas in accordance with procedures and minima in
this chapter. For those situations not covered by this
chapter, the provisions in this Order shall apply.
8-1-3. VFR FLIGHT PLANS
VFR flights in Oceanic FIRs may be conducted in
meteorological conditions equal to or greater than
those specified in 14 CFR Section 91.155, Basic VFR
weather minimums. Operations on a VFR flight plan
are permitted only between sunrise and sunset and
only within:
a. Miami, Houston, and San Juan Oceanic Control
Areas (CTAs) at or below FL 180.
b. Within the Oakland FIR when operating less
than 100 NM seaward from the shoreline within
controlled airspace.
c. All Oceanic FIR airspace below the Oceanic
CTAs.
8-1-4. TYPES OF SEPARATION
Separation shall consist of at least one of the
following:
a. Vertical separation;
b. Horizontal separation, either;
1. Longitudinal; or
2. Lateral;
c. Composite separation;
d. Radar separation, as specified in
Chapter 5, Radar, where radar
coverage is adequate.
8-1-5. ALTIMETER SETTING
Within oceanic control areas, unless directed and/or
charted otherwise, altitude assignment shall be based
on flight levels and a standard altimeter setting of
29.92 inches Hg.
8-1-6. RECEIPT OF POSITION REPORTS
When a position report affecting separation is not
received, take action to obtain the report no later than
10 minutes after the control estimate, unless
otherwise specified.
8-1-7. OCEANIC NAVIGATIONAL ERROR
REPORTING (ONER) PROCEDURES
FAAO 7110.82, Monitoring of Navigation, Longitudinal Separation, and Altitude Keeping
Performance in Oceanic Airspace, contains procedures for reporting and processing navigational
errors observed by ATC radar for aircraft exiting
oceanic airspace.
NOTE-
FAAO 7110.82 establishes procedures for processing
ONER procedures, Oceanic Altitude Deviation Reports,
Erosion of Longitudinal Separation Reports, Letter of
Authorization Verification Reports, and for collecting
system data for analysis. This data is needed for risk
modeling activities to support separation standard
reductions.
8-1-8. USE OF CONTROL ESTIMATES
Control estimates are the estimated position of
aircraft, with reference to time as determined by the
ATC automation system in use or calculated by the
controller using known wind patterns, previous
aircraft transit times, pilot progress reports, and pilot
estimates. These estimates may be updated through
the receipt of automated position reports and/or
manually updated by the controller. Control estimates
shall be used when applying time-based separation
minima.
