- Simpler Operational Qualification and Approvals
- Easy Transferability from Special to SAAAR
- Conclusions

## Operational Objectives and Requirements

- Performance based operations leveraging existing aircraft capability with an evolution path for advanced technology and ATM systems, all for capacity, efficiency and safety

## What Is the Measure of Success

- Implementation that meets/exceeds expectations i.e. schedule
- Global interoperability
- Value and Benefits to users leading to investment in upgrades and advanced aircraft capabilities
- Simpler operation qualification and approvals e.g. like GPS RNAV today
- Easy transferability from Special to SAAAR
- Benefits to ATC/airports resulting in demand

## Expectations

- Published regulatory guidance material
- AC90-100, AC90-101, & Notice 8260.52.   Basic RNP approach, updated AC90-100A, updated AC120-29A RNP, etc in progress.
- Published procedures
- 25 SAAAR planned for 2006, 28 published with 5 additional developed.  Total of 37 so far.  25 more planned for 2007.  Enough?
- Operator Approvals
- Fleet approvals expected for all RNP certified aircraft and systems.  So far, only SAAAR, and limited. Some discouraged by the approval process.
- Basic RNP desired by regional and private aircraft is awaiting criteria and process.

**Notes:**
This is an FAA slide. Delta is in  final process of 757/767 approval and 777.

## Global Interoperability

- US, Europe, Canada, Japan, IFALPA, Industry coordination in the development of ICAO manual for Performance Based Navigation.
- Manual clarifies concepts of RNAV and RNP, providing for consistency in both existing and new criteria to the greatest extent possible.
- Manual expected 2nd or 3rd quarter 2007.
- Regulatory Guidance and Approvals
- Differences exist today.  PBN Manual is expected to facilitate convergence.
- Address GPS interference mitigation and unaugmented GPS
- Aircraft/Operator Approvals
- Foreign approvals easier for foreign carriers than US carriers.  Domestic Foreign carrier approvals not taking place yet.

## Value and Benefits to Users, ATC/Airports

- RNAV SIDS/STARs
- Operators using existing FMS and RNAV capabilities that are resulting in operational improvements & savings i.e. time/fuel
- RNP SAAAR
- Initial sites are seeing improved access (PSP, PDX) as well as time/fuel savings.  Air Transport operators seeking to leverage certified RNP capabilities of their fleets.  Other aircraft and rotorcraft are waiting in line.  We are in a learning state.
- Nav Evolution Assumptions
- Questions being raised by some on the validity of assumptions for adoption of LPV, LPV200, 2008 drawdown of ILS and cost responsibility for Cat II/III operations.
- Benefits must be wide-spread and identifiable
- EVS for low visibility operations not validated for all users

## Simpler Operational Qualification and Approvals

- Aircraft Operational Qualification
- Achieved for 737, A320, Q400, but significant levels of post-certification airworthiness analysis and data required.  757/767, 777, A330, etc in progress.  Challenges include approvals consistent with their certification, and reexamination of aircraft.
- Potential complications from current criteria that appears to preclude use of electronic map for lateral deviation, implication of required deviation display and format, implication of double jeopardy for system safety assessment.
- Wide range of aircraft that must be considered e.g. military, regional jets, rotorcraft, etc
- Operator Approvals
- Applicant process and packages are extensive, and subject to delays associated with a new review process.  Any equipment software change invalidates existing approval.

## Easy Transferability from Special to SAAAR

- Now a unique case, few domestic operators proceeding with RNP specials (i.e. AC120-29A).  Few operators have such approvals.  Today, transfer equals reapplication under AC90-101, no alleviation granted.
- Some specials must remain specials.
- Foreign carriers are proceeding with RNP Specials that consider both AC90-101 and AC120-29A.  Foreign carrier approvals requests have begun for US destinations with RNP SAAAR procedures.  No alleviation granted so far.

## Conclusions

- Performance Based Navigation is a journey
- Current RNP SAAAR operations and criteria are not at the level expected.
- Issues being raised require attention and evolution in processes, guidance material and a single set of regulatory criteria to effectively integrate new technology, RNP SAAAR, RNP, RNAV, and global operations.
- The communication and approval processes need improvement.  Need agreement on critical priorities and schedules.
- Everybody needs to be involved.  More resources are needed to do the work.
