Description IFD Functionality
“Cooperative”
electronics The “cooperative”
system is even more
capable than the IFD
and, therefore, is the
primary navigation
control device.
All nav source selection
and course setting is
performed on the
external device.
The IFD becomes a
“slave” to the external
device.
Course values will
display on the IFD
but are set on the
external device(s).
Nav source modes
available:
None (the nav
source knob/button
will appear to be
non-functional).
NOTE
Manual Sequencing May Be Required
In Electro-mechanical installations where the IFD
does not have an altitude input, a CAS message
(“Manual Sequence Req’d”) prompting the pilot to
manually sequence legs of the flight plan will be
presented on Heading-to-Altitude leg types (e.g.
some missed approach legs). Since the IFD does
not know altitude in this case, it does not know when
to sequence to the next leg. Failure to manually
sequence to the next leg will result in the IFD
maintaining the leg heading indefinitely.
