  1. SBAS Implementation in theregions of ACAC and ASECNAProject with Community research fundingAl-Hoceima Demonstration

  2. Summary of the activities • Introduction: Why Al-Hoceima? • RNAV GNSS Proceduredesign • Flight ValidationCampaign • Business Case (Egisavia) • Safety Case (Navya) • Lessonslearned

  3. Introduction: Why Al-Hoceima? First intention was to design, validate and operationally implement an APV SBAS procedure in Casablanca AD. However the on-going installation of a new ILS for RWY 17R made us to reconsider the situation: • The APV SBAS procedures in ILS-equipped runways are used only as a back-up • The advantages of APV SBAS procedures are much more tangible in small and medium airports with no ILS In particular, Al-Hoceima AD presented the following characteristics: • Small airport with only VOR/DME approaches • Challenging scenario, with MDH of NPA rounding 2000 ft • Low traffic figures: chance for traffic growing evident • Interest of RAM • Better EGNOS availability

  4. Procedure design RNAV GNSS Proceduredownto LPV minima • Today VOR/DME Non-precisionApproaches: • New RNAV LPV Procedure: Al-Hoceima Minimareduction of more than 500 ft Vertical guidanceduringthe Final ApproachSegment No depedanceongroundnavigationaids

  5. Flight Validation Campaign • Flight Validation campaign in Al-Hoceima

  6. Flight Validation Campaign • Flight Validation campaign in Al-Hoceima 7 approaches: - Standard LPV approach - Obstacle assessment in FAS segment - 2 Horizontal sensibility check - 3 Missed Approach Obstacle assessment Excellent EGNOS Performance PerfectFlyability Pilots feedback: TheOperationwaseasier… TheAccuracywasbetter… …than VOR basedprocedures Thecockpitworkloadwaslighther…

  7. Flight Validation Campaign • Flight Validation Equipment • The system (standalone platform) included a Septentrio PolaRX2 GPS/SBAS receiver, whilst the data was also recorded by using ARINC output labels of the GNS480. • In addition, the PILDO in-house flight validation platform has been used for the validation too. • PILDO in-house Flight Validation BENEFITS: • Reduce Time and Cost To Validate GNSS RNAV Procedures (Including SBAS enhanced procedures) • PORTABLE and Adaptive solution to any AIRCRAFT • No NEED of 3rd CODING PROVIDERS to codify Procedures • PROVIDE High integrity and Quality ASSURANCE THROUGHT all the Validation process • Provide Real time Position error estimation • Provide In-flight Validation Health Monitoring • SAVE-Time on In-Flight Decision • Validation of Curved approach Procedure • Post-flight Vision And Processing • Automatic Report Generation • Provide Support and Guidance to the Pilot (CDI/VDI)

  8. Lessons learned APV SBAS Advantages: Aircraft Operators Leading to: • Optimised approach routing from various arrival directions • Optimum descent profile • Engine-idle descents • Improved track keeping • Use of more flexible route and procedure designs • Reduced fuel burn and noise footprints • Reduced environmental impact • Reduced Radio Traffic (R/T) • Reduced controller and pilot workload • Reduced delays, diversion and cancellations due to bad weather • Reduced costs Airports and Air Navigation Service Providers • Limited need for ground infrastructure • Can be implemented in areas where ILS cannot be sited for terrain or obstacle reasons • Can provide approaches to more runways without additional infrastructure costs • Increase the usability of many airports
