CAR/SAM ATN GNSS SEMINAR VARADERO, CUBA 8 MAY 2002 PROCEDURES FOR AIR NAVIGATION SERVICES- OPERATIONS (PANS OPS ICAO DOC. 8168) Barry Billmann Federal Aviation Administration Presentation GNSS 6.1

OVERVIEW RESULTS OF OBSTACLE CLEARANCE PANEL (OCP-12) MEETING JULY 1999 CONCERNING GNSS CURRENT OCP ACTIVITIES REGARDING GNSS AND AUGMENTED GNSS ILS EQUIVALENCE METHODOLOGY FOR CRITERIA DEVELOPMENT BAROMETRIC VNAV GOALS FOR OCP 13

OCP 12 OUTCOMES-BASIC GNSS RESULTS INCLUDED IN PANS OPS AMENDMENT 12 Effective November 2001 PANS OPS VOL. I (PILOT INFORMATION) Chapter 7 Part II Basic GNSS Procedures Equipment Operational Characteristics Equipment Performance Characteristics Annex 10 Information Augmented with RTCA DO VOL. I MATERIAL TO BE UPDATED WITH AMENDMENT 13 OTHER PRODUCTS – CHARTING AND PROCEDURE NAMING

OCP 12 OUTCOMES-BASIC GNSS PANS OPS VOL. II CRITERIA BASED ON ANNEX 10 PERFORMANCE & BASIC GNSS AVIONICS REQUIREMENTS BASIC GNSS RNAV CRITERIA Non-Precision Approach (LNAV) Departure Criteria Terminal Arrival Criteria BAROMETRIC VNAV CRITERIA LNAV/VNAV Criteria Will Be Updated at OCP-13

OCP 12 OUTCOMES-BASIC GNSS GNSS RNAV CRITERIA USES BOTH ACCURACY AND INTEGRITY PERFORMANCE REQUIREMENTS Criteria is Tighter than DME/DME RNAV or VOR/DME Criteria Uses Linear Nature of GNSS Navigation System Error US TERPS & PANS OPS CRITERIA CONSISTENCY Differences in Barometric VNAV Surfaces

CURRENT OCP ACTIVITIES BASIC GNSS FOCUS IS ON VERTICALLY GUIDED APPROACHES IN RESPONSE TO ICAO CFIT INITIATIVE DEVELOPMENT OF VISUAL PROTECTION SURFACE FOR VERTICALLY GUIDED APPROACHES Similar to US TERPS Glideslope Qualification Surface (GQS) PANS OPS VOL. I Update Pilot Information on Multi-Sensor RNAV Include Information on Barometric VNAV Procedures

COLD TEMPERATURE COMPENSATION INFORMATION FOR BAROMETRIC VNAV PROCEDURES IN VOL. I & II PANS OPS VOL. II AMENDMENTS Update Barometric VNAV Criteria Closer to US TERPS Criteria Visual Protection Surface For Vertically Guided Approaches Slightly Steeper than Annex 14 Surface CURRENT OCP ACTIVITIES BASIC GNSS

Dual Element Temp. Probe & Air Data Sensor Static Source (2)Pitot Tube (2) VNAV SENSOR ELEMENTS CONVAIR COLD TEMP TESTING

COMPARISON WITH PANS OPS ALTITUDE ERROR FOR –10 o C HAA* PANS TEST MEAN TEST MEAN + 2 SD Notes: All Values In Feet HAA = Height Above Airport

COMPARISON WITH PANS OPS ALTITUDE ERROR FOR –20 o C HAA* PANS TEST MEAN TEST MEAN + 2 SD Notes: All Values In Feet HAA = Height Above Airport

Steeper than Standard Lapse Rate: Lapse Rate Lessens Close to Surface “Conservative” Error In GPA Close to DA & Excellent Compensated Performance

BASIC GNSS HELICOPTER POINT-IN-SPACE PROCEDURES

CURRENT OCP ACTIVITIES- SBAS SATELLITE BASED AUGMENTATION SYSTEM (SBAS) VOL. I MATERIAL DRAFTED SBAS VOL. II MATERIAL SBAS Precision Approach Criteria SBAS Terminal Criteria SBAS VOL. II MATERIAL DIFFERENTIATING BAROMETRIC VNAV PERFORMANCE FROM SBAS VERTICAL PERFORMANCE NEW SBAS APPROACH PERFORMANCE SERVICE - LPV Lateral Performance Equivalent to Localizer (HAL = 40 m) Vertical Performance (20 m < VAL < 50 m)

CURRENT ACTIVITIES-GBAS GROUND BASED AUGMENTATION SYSTEM (GBAS) VOL. I MATERIAL Differences Between SBAS and GBAS ILS Look Alike Performance on Final Approach Segment Lateral & Vertical Deviations and Distance to Threshold GROUND BASED AUGMENTATION SYSTEM (GBAS) VOL. II MATERIAL Precision Approach Criteria Use of ILS Cat. I Collision Risk Model for GBAS Procedure Design

CURRENT ACTIVITIES ILS EQUIVALENCY DEMONSTRATE GBAS AND SBAS ACCURACY PERFORMANCE EQUIVALENT TO CAT. I ILS OCP-12 REPORT DESCRIBED METHODOLOGY Well Structured Flight Tests TSE Performance Per Collision Risk Model Manual TSE, FTE, NSE Performance Per RNP Manual For Approach, Landing & Departure Operations (Draft) RESPONSE FROM 2 STATES AND 1 ORGANIZATION RESULT: EQUIVALENCE DEMONSTRATED Criteria to be Based on Existing ILS Criteria

KING AIR GPS INSTALLATION

EUROCONTROL/UK NATS GBAS TRIALS

OTHER CURRENT ACTIVITIES DEVELOP CRITERIA SPECIFICALLY FOR BAROMETRIC VNAV DEVELOP SBAS TERMINAL CRITERIA THAT IS MORE STRINGENT THAT BASIC GNSS TERMINAL CRITERIA FINALIZE SBAS APPROACH PERFORMANCE LEVELS GNSS PANEL OBSTACLE CLEARANCE PANEL OPERATIONS PANEL

PLANS FOR OCP - 13 MEETING IN MONTREAL IN OCTOBER 2002 RESULTING AMENDMENTS TO BE EFFECTIVE NOVEMBER 2004 PANS OPS VOL. I AMENDMENTS FOR: Basic GNSS with Barometric VNAV SBAS Performance Levels GBAS Described as ILS Look Alike Procedure

PLANS FOR OCP - 13 DESCRIPTION OF NEW SURFACE CALLED THE VISUAL PROTECTION SURFACE FOR VERTICALLY GUIDED APPROACHES ADMENDMENT OF BASIC GNSS BAROMETRIC VNAV CRITERIA SBAS AMENDMENTS Terminal and Precision Approach Criteria OTHER ACTIVITIES Precision and “LOC” Only Criteria Use of Cat.
