March 2010

• S-101 represents a major step forward in product specifications for Electronic Navigational Charts.
• This consists mainly of new feature types to overcome existing issues (e.g. overuse of caution areas) and improved functionality leading to more efficient data handling.
• As a result, TSMAD is proposing a phased approach for the development , testing, and release of S-101*
*Approved TSMAD 19

• Planning
– Phased Approach
• Analysis
– Stakeholders Input
• Design
– Test Beds
• Implementation
• Maintenance

• Iterative Development
– Each iteration is usable and testable
• Controlled change
– Enables a test of the change control process to both S-101 and S-100
• Enables smooth migration
– Manageable change
• Will mitigate type approval concerns
– Ensure that S-101 catalogues are not software or hardware updates
• Does not try and solve everything at once
• Enables stakeholders to phase their development implementation of S-100 based product specifications
