This transition normallyoccurs within 2.0 nm of the final approach fix (FAF). The CDI changes to approach scaling automaticallyonce the approach procedure is activated or if Vectors-To-Final (VTF) are selected.- If the active waypoint is the FAF, the ground track and the bearing to the FAF must be within 45° of thefinal approach segment course.- If the active waypoint is part of the missed approach procedure, the active leg and the preceding missedapproach legs must be aligned with the final approach segment course and the aircraft must not havepassed the turn initiation point.Figure 2-24 Typical LNAV, LNAV+V, and Visual Approach CDIScaling1.0 nm2 nm350 ftangle setby system0.3 nmFAFCDI Full-scale Deflection CDI scale is set to the smaller of 0.3 nmor an angle set by the systemCDI scale varies if VTF is activatedFigure 2-25 Typical LNAV/VNAV, LPV, LP+V, and LP ApproachCDI Scaling1.0 nm2 nmFAF0.3 nmcourse widthLandingThresholdCDI Full-scale Deflectionangle basedon databaseinformationCDI scale varies if VTF is activated• When a missed approach is activated, the CDI scale changes to 0.3 nm.• The system automatically switches back to terminal mode 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 a CA, CD, CF, CI, CR, DF, FA, FC, FD, FM, IF, or TF- After any leg in the missed approach procedure that is not a CA or FA
