Figure 2-25 Automatic CDI Scaling
• Once a departure procedure is activated, the CDI is scaled for departure (0.3 nm).
• The system switches from departure to terminal CDI scaling (1.0 nm) under the following conditions:
- If the next leg in the departure procedure is not aligned with the departure runway
- If the next leg in the departure procedure is not a CA, CD, CF, CI, CR, DF, FA, FC, FD, FM, IF, or TF leg
- After any leg in the departure procedure that is not a CA or FA leg
• Thirty nautical miles from the departure airport (or at the last departure waypoint if farther than 30 nm
from the departure airport), the system automatically selects the enroute phase of flight and changes the
CDI scaling to 2.0 nm over a distance of 1.0 nm.
• If after completing the departure procedure the nearest airport is more than 200 nm away from the aircraft
and the approach procedure has not yet commenced, the CDI is scaled for oceanic flight (2.0 nm).
• Within 31 nm of the destination airport (terminal area), the CDI scale gradually ramps down from 2.0 nm
to 1.0 nm over a distance of 1.0 nm; if a transition back to enroute flight occurs, the CDI scale increases
back to 2.0 in the same manner.
• During approach operations, the CDI scale ramps down even further (see Figures 2-26 and 2-27). This
transition normally occurs within 2.0 nm of the final approach fix (FAF). The CDI switches to approach
scaling automatically once any portion of the approach procedure becomes active or if Vector-to-Final
(VTF) is selected.
- If the active waypoint is the FAF, the ground track and the bearing to the FAF must be within 45° of the
final approach segment course.
- If the active waypoint is part of the missed approach procedure, the active leg and the preceding missed
approach legs must be aligned within 3° of the final approach segment course and the aircraft position
must be prior to the turn initiation point.
