CDI scale varies if VTF is activated
Figure 2-26 Typical LNAV and LNAV+V Approach CDI Scaling
• When a missed approach is activated, the CDI scale changes to 0.3 nm.
• The system automatically switches back to terminal scaling under the following conditions:
- The next leg in the missed approach procedure is not aligned with the final approach path
- The next leg in the missed approach procedure is not CA, CD, CF, CI, CR, DF, FA, FC, FD, FM, IF, or TF
- After any leg in the missed approach procedure that is not CA or FA
