SECTION 2 - WATRS Plus Airspace Redesign and Separation Reduction Project

Project Decription: On 5 June 2008, the FAA is planning on introducing a redesigned route structure and a reduced lateral separation standard in WATRS Plus CTAs. The redesigned route structure is based on introducing 50 nm lateral separation between aircraft that are authorized Required Navigation Performance 10 (RNP 10) or RNP 4.

The FAA “WATRS Plus Operational Policy & Procedures Notice” posted below under “Operating Policy” provides project objectives, operating policies and operator requirements.

- FAA Order 8900.1, E-Handbook. Inspector guidance in paragraph 4-107 (RNP in Class II Airspace) is followed in the RNP 10 Job Aid. Paragraph 4-107 is in E-Handbook Vol. 4, Chapter 1, Section 5 (Special Navigation Areas of Operation). Search on “RNP-10” (Include dash (-)).
- FAA Order 8400.33 (Authorization for RNP 4 in Oceanic & Remote Area Operations) is posted above and is posted on the Flight Standards Information Management System (FSIMS). Search on “RNP-4”. (Include dash (-). URL is http://fsims.faa.gov/. Order 8400.33 is followed in the FAA RNP 4 Job Aid.
- E-Handbook Volume 4, Chapter 12 is “Issue/Renew LOA for Operations in Special Use Airspace”. It is not related to WATRS Plus operations. It focuses on North Atlantic MNPS operations. It also includes the old manual LOA format.
- RNP 10 and RNP 4 Job Aids are posted in the “FAA RNP Authorization Policy & Procedures” section above.
