Collins Proline 21

The FMS 5000 in the Collins system has many configuration and display options. I think one of the best for SA (Situational Awareness) is the Display Menu(DSPL MENU). Here you have options that you can display on the MFD like Nearest Airports, Hi & Lo Nav Ids, etc...

These options give better Awareness if things were to go south in a hurry. You will be one or two steps ahead having this information available for a better outcome in a potential Fire/Smoke, Engine Loss or Pressurization Problem.
