Part <strong>II</strong>I — Section 3, Chapter 3 <strong>II</strong>I-3-3-3<br />

3.2.5.3 This last width may be reduced to ±5.56 km (3.00 NM) if the provisions <strong>of</strong> Part I, Section 4, Appendix B<br />

to Chapter 3 are employed.<br />

3.2.5.4 Missed approach secondary areas for basic GNSS. Until further operational experience is obtained with<br />

basic GNSS receivers — some <strong>of</strong> which may not provide continuous track guidance after the MAPt — the full MOC<br />

applicable to the primary area should be applied to the full width <strong>of</strong> the missed approach area. That is, the principle <strong>of</strong><br />

secondary areas does not apply. On the other h<strong>and</strong>, if a procedure is designed exclusively for use by aircraft equipped<br />

with multi-sensor systems, the missed approach criteria in 7.3.5, “Turn initiated at a designated turning point (TP)”<br />

apply, <strong>and</strong> the approach procedure shall be so annotated.<br />

3.2.5.5 Straight missed approach for basic GNSS. The criteria governing straight missed approaches apply (see<br />

Part I, Section 4, Chapter 6, 6.3, “Straight missed approach”). Note that the 15° splay provided for the basic GNSS<br />

receiver is limited by the width <strong>of</strong> the area defined by the subsequent waypoint in the missed approach (MATF or<br />

MAHF). See Figure <strong>II</strong>I-3-3-3.<br />

3.2.6 Missed approach area width for RNP<br />

See Section 1, Chapter 7, 7.5, “XTT, ATT <strong>and</strong> area semi-width”.<br />
