Indications from this FMS are shown on the bearing  pointer (blue needle). Navigation sources can be coupled to navigation indicators using  the key to the left. Selections are indicated in the boxes to the right. Figure 3-16. Coupling the FMS to navigation instruments. Awareness: Mode Awareness Mode awareness refers to the pilot’s ability to keep track of  how an  advanced avionics cockpit system is configured. As  shown in  Figur e 3-16,  every advanced avionics system offers  an annunciation  of which mode is currently set—somewhere  in the cockpit! T here is no guarantee that you will notice these  annunciations i n a timely manner. The configuration of these  systems must re main part of your mode situational awareness  at all times. One strategy is to include “mode checks” as part  of your  checklist or callout procedures. For example, after  programming a  route into the FMS, verify that the navigation  indicator shows  course guidance from the desired source, and  that the  indicatio n agrees with your estimate of the correct  direction and distance of flight. The FMS provides guidance toward each waypoint in the  programmed flight route, and provides information to help  you track your progress. Essential Skills En Route Navigation 1. Determi ne whether the FMS is approved for the  planned flight operation. 2. Determi ne if your FMS can be used as a primary  navigation system for alternate requirements. 3. Understand how entries are made and how the entries  can be canceled. 4. Understand how that unit(s) is installed, and how it is  programmed or jumpered for optional functions. 5. Determine which navigation sources are installed and  functional. 6. Determine the status of the databases. 7. Program the FMS/RNAV with a flight plan, including  en route waypoints, user waypoints, and published  instrument procedures. 8. Review the programmed flight route to ensure it is  free from error. 9. Find the necessary pages for flight information in the  databases. 10. Determine which sources drive which displays or  instruments, and where the selection controls are  located. 11. Determine and understand how to use and program  optional functions and equipment installed with FMS/ RNAV basic unit. 3-13
