Federal Aviation 0 Administration 0 Session 4 RNP – The Expectations? Certification Issues Federal Aviation 1 Administration 1 RNP Airworthiness & Operational Implementation in the U.S. Federal Aviation Administration Presentation to: EurocontrolWorkshop – “Implementing RNP” Toulouse, France Barry Miller Aircraft Certification Lead for U.S. RNP Implementation FAA Avionics Standards Branch, Aircraft Certification Service (AIR-130) October 5, 2005 Federal Aviation 2 Administration 2 RNP Airworthiness & Operational Implementation Overview RNP Strategy – A Change in Perspective The “Three-Legged Stool” RNP Operational Approval Background: Aircraft Certification The Role of Aircraft Certification The Role of the Manufacturer Federal Aviation 3 Administration 3 RNP Strategy – A New Perspective • Tradition Design Airspace Around the Aircraft Example – Implementation of ILS Procedures • New Paradigm Define the Airspace to Meet Operational Needs Define the Operational Procedures Design Criteria to Meet Airspace Definition TERPS or PANS-OPS Then, Define the Aircraft Requirements for Operations in the Airspace • The RNP Strategy “A Three-Legged Stool” Air Traffic Criteria Operations Criteria Including Procedure Design Criteria Aircraft Qualification Criteria Federal Aviation 4 Administration 4 The “Three-Legged Stool” • Define the Air Traffic Criteria Define the Airspace Air Traffic Control Procedures • Define the Operations Criteria Procedure Design Criteria Operational Performance Requirements • Define the Aircraft Qualification Requirements Find Foundation in the Operational Criteria Embrace Existing RNP Airworthiness Approvals Define Operational Mitigations Federal Aviation 5 Administration 5 RNP Operational Approval • Define the Aircraft Performance Characteristics Applicability to Desired RNP Procedures Examples: RF Turn Capability, TOGA Performance • Develop Pilot Operations & Training Requirements Aircraft System Operations Related to the RNP Procedures Example: GNSS Required A Starting Point Pilot Alerting & Operational Limitations for RNP Procedures New Pilot Procedures to Accommodate FTE Monitoring Go-Around Capability Exists & Does Not Exceed Containment • Ensure Support for Database Integrity Use of Approved Database Suppliers Letter of Acceptance (LOA) Operator-Defined Database Configuration Control Applicability of Operational Database Checks – Simulator & Aircraft Federal Aviation 6 Administration 6 Background: Aircraft Certification • Airworthiness Key Intended Function 14 CFR 25.1301 & 25.1309 Intended Function • Absent RNP Standards Document Aircraft Capability & Performance The Aircraft Flight Manual (AFM) Does Not Constitute Operational Approval RNP Airworthiness Approvals for Many Aircraft Boeing, Embraer, Gulfstream ~ Airbus Federal Aviation 7 Administration 7 Role of FAA Aircraft Certification • Support the Operations Approval Define Aircraft Performance Characteristics Alerting – Display Scaling – TOGA – Inertial Performance Approve Data Suppliers FAA AC 20-153 LOA • Support New Aircraft & Certification Projects (TC/STC) Future: Draft FAA Advisory Circular 90-RNP SAAAR Approval for Required Navigation Performance (RNP) Procedures with Special Aircraft & Aircrew Authorization Required (SAAAR) Expect Manufacturer to Use Specific, Defined Criteria Federal Aviation 8 Administration 8 Role of Aircraft OEMs • Document Aircraft Performance Examples: Altimetry System, Flight Technical Error (FTE)… • Assist Aircraft Customers Achieve Ops Approval • Provide Aircraft Qualification & Operations Guidance Tailored to the Specific RNP Operation Minimum Equipment List for the RNP Operations Systems Operations to Achieve the RNP Recommend Pilot Procedures for RNP Procedures Pilot Monitoring Requirements Pilot Response to Alerts & Annunciations of Performance Flight Technical Error (FTE) Limitations System Crosschecks Aircraft-Specific Operational Mitigations Federal Aviation 9 Administration 9 Summary of RNP Airworthiness & Operational Implementation RNP Strategy – A New Paradigm Balancing a “Three-Legged Stool” RNP Operational Approval The Role of Aircraft Certification The Role of the Manufacturer Federal Aviation 10 Administration 10 Federal Aviation 11 Administration 11 Session 4 RNP – The Expectations?
