The co-pilot will, amongst other tasks, usually read you through the checklists (although you are free to decide who should read the checklist when you create your own checklists), make flap calls, and make the speed calls at take off.
You can enable or disable the co-pilot entirely, or you can enable or disable a group of calls that should be made.
The co-pilot is also responsible for making the prepare for take-off call to your cabin crew. You have several options for enabling this call.
Hotkey: The call is made when you hit the hotkey (same as
Turbulence Warning hotkey).
Auto: The call is armed when you stop the aircraft after taxiing
from the terminal. The call is played the moment the aircraft starts moving again, assuming that you are now rolling onto the runway and ready to take off.
Before takeoff checks: The announcement is made immediately
before you start the takeoff checklist.
After takeoff checks: The announcement is played once the
before takeoff checklist is complete.
You should select the option that best suits your taxiing habits. If you for various reasons have to start and stop your aircraft several times while taxiing (as a result of other airport traffic or similar), one of the two last options might be good, since they prevent the announce- ment from being armed far too early.
Note! Using the hotkey to trigger the announcement also provides an easy way to set FDC Live Cockpit! 2011 in the Ready for takeoff phase. This allows you to start the flight in a quick way.
New electronics and more technically advanced cockpits have more or less made the engineer superfluous in modern airliners. However, on old, large airliners, the cockpit crew usually included an engineer to take care of technical and navigational tasks. In FDC Live Cockpit!
