The PBN and Cockpit Workshop Technical Requirements

Dive into the world of Flight Technical Error (FTE), Flight Operational Safety Assessment (FOSA), and Engine Out SID (EOSID) in this informative workshop led by Don-Jacques OULD FERHAT. Explore the nuances of FTE assessment, statistical distribution, and FOSA guidelines to enhance operational safety and performance. Unveil the significance of EOSID in ensuring obstacle clearance and compliance with certification specifications and operating rules.

1. PBN and the Cockpit Workshop Technical Requirements FMS Operations and Aircraft Performances Don-Jacques OULD FERHAT Quovadis COO, October 18th2012

2. Summary of Existing Technical Requirements Flight Technical Error (FTE) Flight Operational Safety Assessment (FOSA) Engine Out SID (EOSID) Project title (Insert, Header & Footer) 2

3. FTE ASSESSMENT Path Definition Error (PDE) Desired Path Defined Path Path Steering Error (PSE) or Flight Technical Error (FTE) with AP ON Total System Error (TSE) Estimated Position Position Estimation Error (PEE) or Navigation System Error (NSE) True Position Project title (Insert, Header & Footer) 3

4. FTE Assessment No failure FTE FTE OEI / System failures Statistical distribution Engine failure or system failures FTE (95%) Wind Wind Project title (Insert, Header & Footer) 4

5. FOSA FOSA stands for Flight Operational Safety Assessment Eurocontrol Guidance Material released in 2010 and ICAO Working Paper few months later But what does it really mean? Project title (Insert, Header & Footer) 5

6. FOSA Guidelines Project title (Insert, Header & Footer) 6

7. EOSID The Departure Sector is defined in the EU-OPS 1.495. The Obstacles are taken into account within a combination of: Cone from as defined in EU-OPS 1.495 Corridor with half-width equal to 2xRNP value Project title (Insert, Header & Footer) 7

8. EOSID Engine Failure at VEF and before DP (Diversion Point) => The EOSID is flown Minimum Obstacle Clearance Minimum Obstacle Clearance EOSID and Obstacle Clearance 0.8% Gross Flight Path 35ft or 50ft Net Flight Path 35ft or 50ft End of Net FP 0.8% 35ft or 50ft Obs n 4 Obs n 3 Obs n 2 Obs n 1 EF at VEF As per: Certification Specifications (CS/FAR 25.111 & CS/FAR 25.115) Operating Rules (EU-OPS 1.495) ICAO PANS-OPS Chap. II.3.1.2 Minimum Obstacle Clearance AC 120.91 9 (Termination of Takeoff segment) Project title (Insert, Header & Footer) 8

9. CONCLUSION FTE assessment methodology should be made available for OEM FOSA guidelines should be endorsed by ICAO and shared EOSID with RNP provide safety enhancement and should be widely promoted Project title (Insert, Header & Footer) 9
