7Video on Performance-Based Navigation(approximate
ly 13 minutes in length)
8What? Terminology Area Navigation (RNAV)
- RNAV is a method of navigation that enables
aircraft to fly on any desired flight path within
the coverage of referenced NAVAIDS or within the
limits of the capability of self-contained
systems, or a combination of these capabilities - Routes and procedures using RNAV provide improved
access and flexibility through point-to-point
navigation and are not restricted to the location
of ground-based NAVAIDs - The overall safety of the RNAV operation is
achieved through a combined use of aircraft
navigation accuracy, air traffic control
intervention (via radar monitoring, automatic
dependent surveillance (ADS), multilateration,
communications) and/or route separation
9Terminology (continued) Required Navigation
Performance (RNP)
- RNP is RNAV with on-board navigation monitoring
and alerting - RNP is a statement of navigation performance
necessary for operation within a defined airspace - A critical component of RNP is the ability of the
aircraft navigation system to monitor its
achieved navigation performance, and to identify
for the pilot whether the operational requirement
is, or is not being met during an operation - This on-board monitoring and alerting capability
therefore allows a lessened reliance on air
traffic control intervention (via radar
monitoring, automatic dependent surveillance
(ADS), multilateration, communications), and/or
route separation to achieve the overall safety of
the operation - RNP capability of the aircraft is a major
component in determining the separation criteria
to ensure that the overall containment of the
operation is met
10Terminology (continued) RNP Special Aircraft
and Aircrew Authorization Required (SAAAR)
- RNP SAAAR is the first public implementation of
RNP in the National Airspace System - Operators must be authorized to fly this type of
procedure - Authorization process is similar to that used for
ILS Cat II/III - Procedures are charted with title of RNAV (RNP)
RWY XX and words SPECIAL AIRCRAFT AIRCREW
AUTHORIZATION REQUIRED below minima box - Some Special RNP SAAAR procedures currently
exist and may be developed in the future
(different process and criteria from Part 97) - Operations into foreign airspace/facilities using
RNP-like procedures may require RNP SAAAR
authorizations
11Why? Benefits of RNP SAAAR
- Provide better access through lower minimums to
runways with terrain/obstacles - Increase use of under-utilized runways (parallel,
converging, standalone) - Improve backup procedures during ILS outages
- De-conflict airspace and traffic flows (e.g.,
converging runways, adjacent procedures) through
narrower and curved segments - Improve safety by eliminating circling maneuvers
and providing lateral and vertical flight
guidance to the runway
12How? FAA Guidance for RNP SAAAR Procedures
- Procedure Development Criteria-
- FAA Order 8260.52 UNITED STATES STANDARD FOR
REQUIRED NAVIGATION PERFORMANCE (RNP) APPROACH
PROCEDURES WITH SPECIAL AIRCRAFT AND AIRCREW
AUTHORIZATION REQUIRED (SAAAR) - Airworthiness and Operational Approval-
- FAA AC 90-101 APPROVAL GUIDANCE FOR RNP
PROCEDURES WITH SAAAR - Note International procedure design criteria
for RNP with Authorization Required will be
harmonized with - FAA Order 8260.52
13RNP SAAAR Procedure Design Features per Order
8260.52
Lateral Width of 2 X RNP with no secondary
buffers at RNP 0.3 nm or less
Curved Segments (optional) (Radius-to-fix legs)
Performance-Based Vertical Criteria (Vertical
Error Budget)
Guided Missed Approaches (optional) (RNP 1.0 or
less)
14AC 90-101 APPROVAL GUIDANCE FOR RNP PROCEDURES
WITH SAAAR
- Developed through coordination with aviation
industry via Performance-Based Aviation
Operations Rulemaking Committee (PARC) - Designed to set a common standard for Operations
and Airworthiness to be in sync with Procedure
Design criteria in - FAA Order 8260.52
- Authorizations issued under the provisions of AC
90-101 may require operational mitigations to
satisfy safety standards
15Guidance for Approvals per AC 90-101
- Aircraft Qualification
- Performance Requirements
- Lateral and vertical accuracy
- Airspace containment- system monitoring and
alerting - Position Updating
- GPS required during initial implementation

16Guidance for Approvals per AC 90-101 (continued)

- Operator requests approval from FAA
- Confirmation of aircraft qualification
- Case 1- Aircraft Flight Manual (AFM) states
compliance with AC 90-101 - -or-
- Case 2- No statement of compliance in the AFM,
then the aircraft Original Equipment Manufacturer
(OEM) and FAA determine airworthiness - -and-
- Compliance with crew procedures and training
specified in AC 90-101 - -then, if satisfactory-
- FAA issues interim authorization and then,
following demonstration period (credit may be
given to experienced operators), final
authorization
17Appendix 1- RNP SAAAR Instrument Approach
Procedures
- Procedure design criteria defined in FAA Order
8260.52 - Characteristics of RNP SAAAR procedures
- Allowance for multiple lines of minima at 0.3 nm
and down to 0.1 nm - RNP 0.3 line of minima will always be
developed, if obstacles and terrain allow - RNP values less than 0.3 nm generally require use
of more automation - RF legs an option throughout procedure and
identified on chart - Missed approach procedure with RNP less than 1.0
nm - Non-standard approach speeds and/or climb
gradients - Initial charting conventions established but work
still ongoing
18Appendix 1- RNP SAAAR Instrument Approach

44Inspector Guidance and Mechanisms for RNP SAAAR
Authorizations
- FAA Notice 8000.316 OpSpec C052 can not be used
for RNP SAAAR - Part 121/135 OpSpecs
- C384 non-standard requiring AFS-200 and AFS-400
approval - Part 129 OpSpecs
- C084 must have CAA authorization for that
country (AFS-50) - Part 91 Subpart K Mspecs
- C384 non-standard
- Handbook Bulletins In development
- International RNP Procedures
- Majority of procedures will be designed with
criteria harmonized with FAA Order 8260.52 and
designated as Authorization Required or AR - Limited number of RNP procedures
(non-harmonized) that require similar performance
to RNP SAAAR - Both types require authorization
45Summary
- RNP SAAAR criteria and guidance documents,
developed in coordination with industry, provide
common standards in these areas - Procedure Design
- Airworthiness
- Operational Procedures and Training
- Identification of appropriate operational
procedures and associated training is important - No intention for field inspectors to qualify
aircraft for RNP SAAAR, rather this function is
accomplished by specific OEM and FAA
representatives (several aircraft models and
operators are currently being reviewed)
