Background
• SEANEAM and FAA acting as project co-leads
• Project coordinated over a 3-year period with
industry, ICAO Mexico City and ICAO
Caribbean Working Groups
• FAA Tech Center completed city-pairs analysis
– $1.5 million savings for 31-day March 2011 period

Acronyms
LOA………Letter of Authorization
NavSpec…Navigation Specification (requirement)
for aircraft navigation systems
PBN………Performance-based Navigation
RNP………Required Navigation Performance
RNAV…….Area Navigation

Terms: RNAV 10 vs RNP 10
• “RNP 10” has same meaning and application
as “RNAV 10”
• Reference ICAO PBN Manual, Volume II,
Part B, Chapter 1: “Implementing RNAV 10,
Designated and Authorized as RNP 10”:
• “RNP 10” used for GoMex project
Federal Aviation
Administration

NavSpecs Applicable in Oceanic
Operations
• ICAO PBN Manual, Edition 3: RNP 10 and
RNP 4 are only NavSpecs applicable to
oceanic operations
• Advance Edition 4 contains provision for RNP 2
– Not a factor for GoMex project
• RNP 10 is the minimum NavSpec required for
50 NM lateral separation
Federal Aviation
Administration
6
Gulf of Mexico Project: Phased
Implementation
• Phase 1: implemented on 20 Oct 2011
– Lateral separation reduced to 50 NM lateral
– Existing GoMex ATS routes remained in place
• Policies for 50 NM lateral separation distributed
to operators
Federal Aviation
Administration
7
Project Objectives
• On 10 Jan 2013 at 0630 UTC, implement new
Gulf RNAV routes --- while retaining two
existing ATS routes
• Apply 50 NM lateral separation between aircraft
authorized RNP 10 (minimum) or RNP 4
• Qualify aircraft equipped with a Single Long
Range Navigation System (S-LRNS) for
RNP 10 in the Gulf of Mexico – in accordance
with ICAO PBN Manual
Federal Aviation
Administration
8
Phase Objectives (cont.)
• Have close to 100% of GoMex flights
authorized and filing for RNP 10 or RNP 4
operations
• Accommodate the operation of the small
percentage of flights not yet authorized RNP 10
• Airspace will not be “exclusionary”,
however, ATS providers advocate that
operators obtain RNP 10 authorization

ICAO FPL 2012 Flight Plan Entries
• Item 10: “R” (PBN approved)
• Item 18 (Other Information) entries
– “PBN/A1” (RNP 10 ) or…
– “PBN/L1” (RNP 4)
• NonRNP 10 aircraft:
– Item 18: “RMK/NONRNP10” (first remark)
• !! Some operators not yet filing RNP 10 or
RNP 4
Federal Aviation

11
NonRNP 10 aircraft
• 50 NM lateral separation cannot be applied to
NonRNP 10 aircraft
• Strongly advocate that GoMex operators obtain
and file RNP 10 authorization to maximize
project benefits
• Single Long Range Navigation System
equipped aircraft qualify for GoMex RNP 10
• Operators can contact [email protected]
for RNP 10 authorization questions
Federal Aviation
Administration
12
NonRNP 10 Pre-coordination
• No earlier than 2 hours prior to departure, ALL
NonRNP 10 operators to contact Houston
Operational Supervisor at +1-281-230-5552
• Provide call sign, route of flight and ETA to
enter Houston FIR
• Pilots to state “Negative RNP 10”
– On initial call to GoMex ATC Center or…
– If status requested by controller

Transition to New Routes-10 Jan 2013
• Transition Sequence of Events planned with
SENEAM and industry representatives
• Point-to-point Transition Routes planned for
aircraft without updated Nav Databases for
0630 - 1500 UTC time period
• Transition route chart and instructions posted
on Webpage and in FAA and SENEAM
NOTAMS (ZHU A0970/12; ZMA A1449/12)
Federal Aviation
Administration
14
•Transition Procedures-10 Jan 2013
• Until 0630 UTC, aircraft will file the EXISTING
GoMex route structure.
• At/after 0630 UTC, aircraft are expected to file
and fly the NEW GoMex route structure,
HOWEVER…between 0630-1500 UTC aircraft
whose navigation computers have not been
updated with NEW GoMex routes may file
direct between stand-alone waypoints
identified in the Transition Routes.

Transition Procedures (cont.)
• At/after 1500 UTC, only Route 2 (A766) and
Route 3 (A770) will be available to aircraft
unable to fly the NEW routes.
• If alternative routes are needed, operators must
call the appropriate Area Control Center prior to
departure.

Significant Elements of Route Design
• A649 LEV-PAZ deleted to move traffic onto M575 and
M345 where crossing traffic can be managed under
radar
• L207 will be a new RNAV route between Scholes
(VUH) and Campeche (CPE)
• A766 will remain as published
• UT40 (DUTNA-SIGMA) to provide new overflight option
• A770 to remain as published, co-designated
UA770/UL209 – A770/L209 south of KEHLI
• Enhanced routing to CUN for flights overflying
CIGAR-MINOW
• Enhanced eastern Gulf overflight routing: M215MINOW-PISAD-UL333-DUVMU-UT29-SIGMA

Route Operations Guidance
• Document provides guidance on one-way
routes, altitude and time restrictions,
recommended arrival and overflight routing,
etc.
• Distributed to industry groups on 30 Nov
• Posted on FAA GoMex Webpage
• Mexican AIP provides route operations
guidance for individual routes
