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

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

4 4Project title (Insert, Header & Footer) FTE Assessment Wind FTE Statistical distribution Wind No failure FTE (95%)

5 5 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) FOSA

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

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

8 8Project title (Insert, Header & Footer) EOSID Engine Failure at V EF and before DP (Diversion Point) => The EOSID is flown Engine Failure at V EF and before DP (Diversion Point) => The EOSID is flown EOSID and Obstacle Clearance As per: Certification Specifications (CS/FAR & CS/FAR ) Operating Rules (EU-OPS 1.495) ICAO PANS-OPS Chap. II – Minimum Obstacle Clearance AC – 9 (Termination of Takeoff segment) As per: Certification Specifications (CS/FAR & CS/FAR ) Operating Rules (EU-OPS 1.495) ICAO PANS-OPS Chap. II – Minimum Obstacle Clearance AC – 9 (Termination of Takeoff segment)

9 9Project title (Insert, Header & Footer) 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
