SBAS Offshore Approach Procedure SBAS Offshore Approach Procedure SBAS Offshore Approach Procedure SBAS Offshore Approach Procedure (SOAP)(SOAP)(SOAP)(SOAP)
�Developed as a safety enhanced procedure
relative to the current ARA and GPS approach procedures
�Benefits include:• less reliance on weather radar
• high navigation accuracy
• provides independent cross-checkagainst existing altimeters
• allows a “straight in” procedure
from final to missed approach
• gives much lower crew workload

In conclusion, SOAP was successfully validated
�Flight crew agreed that SOAP is more precise than existing low visibility options
�Horizontal and vertical track keeping is precise but could be improved with changes to HMI
�Crew comments proposed some improvements to the HMI
�Further work in the area will be undertaken• UK CAA sponsoring HMI enhancements and
additional flight trials in June
