INDEX
When set to Auto (default), the GPS CDI scale automatically adjusts to the desired limits based upon the
current phase of flight (Figure 2-21, Table 2-1).

Refer to accompanying
approach CDI scaling figures
• 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:
- The next leg in the departure procedure is not aligned with the departure runway
- The next leg in the departure procedure is not a CA, CD, CF, CI, CR, DF, FA, FC, FD, FM, IF, or TF (see
Glossary for leg type definitions)
- After any leg in the departure procedure that is not a CA or FA
• At 30 nm from the departure airport, the enroute phase of flight is automatically entered and CDI scaling
changes to 2.0 nm over a distance of 1.0 nm, except under the following conditions:
- When navigating with an active departure procedure, the flight phase and CDI scale does not change
until the aircraft arrives at the last departure waypoint (if more than 30 nm from the departure airport) or
the leg after the last departure waypoint has been activated or a direct-to waypoint is activated.
• 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; except under the following conditions:
- When navigating with an active arrival route, the flight phase and CDI scale does not change until the
aircraft arrives at the first waypoint in the arrival route (if within 31 nm from the destination airport).
• During approach, the CDI scale ramps down even further (Figures 2-22 and 2-23). This transition normally
occurs within 2.0 nm of the final approach fix (FAF). The CDI switches to approach scaling automatically
once 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 the
final approach segment course.
