•Thesystemswitchesfromdeparturetoterminal CDI scaling (1.0 nm) under the following conditions:
- The next leg in the procedure is not aligned with the departure runway
-
The next leg in the departure procedure is not 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 CA or FA
•At30nmfromthedepartureairporttheenroute 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.
•Ifaftercompletingthedepartureprocedurethenearestairportismorethan200nmawayfromtheaircraft
and the approach procedure has not yet commenced, the CDI is scaled for oceanic flight (2.0 nm).
•Within31nmofthedestinationairport(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 arrive route (if within 31 nm from the destination airport).
•Duringapproach, 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 the approach procedure is activated 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 preceding missed
approach legs must be aligned with the final approach segment course and the aircraft must not have
passed the turn initiation point.
