management practices are consistent with the criteria of document DO-200A/ED-76. The database<br />
supplier of an operator must have a Type 2 LOA, and their respective suppliers must have a Type 1 or 2<br />
LOA. The <strong>CA</strong>A may accept a LOA issued to the navigation data suppliers or issue its own LOA.<br />
6. AIRCRAFT MODIFI<strong>CA</strong>TIONS (UP DATE OF THE DATA BASE)<br />
If an aircraft system required for <strong>RNP</strong> <strong>APCH</strong> operations is modified (e.g., a change in the software), the<br />
operator is responsible for validation of <strong>RNP</strong> <strong>APCH</strong> procedures with the navigation database and the<br />
modified system. This may be accomplished without any direct evaluation if the manufacturer verifies that<br />
the modification has no effect on the navigation database or path computation. If this verification is not<br />
done by the manufacturer, the operator must carry out an initial validation of the navigation data with the<br />
modified system.<br />
