IFD400 Series Pilot Guide
5-8 Navigation
NOTE
Aircraft Integration
The nav sources available in your airplane will be
dependent on the level of integration with other on-
board systems. Avidyne strongly recommends
practice operations in VMC conditions before any
use in IMC, to understand the level of integration
between the IFD and the other on-board systems
and, therefore, the nav sources available.
The nav source knob is labeled “CDI” above the knob and is
designed to allow you to toggle the CDI and system nav source
between the active and armed states defined above.
