2.4 ABNORMAL OPERATIONS

The annunciations listed in the table can appear on the HSI when abnormal GPS conditions occur.

Annunciation

In Dead Reckoning (DR) Mode the CDI is removed from the display when GPS is the selected navigation

source. The following items on the PFD are then shown in amber:

• Current Track Bug

• Wind Data (calculated based on GPS information)

• Distances in the Bearing Information Windows

• GPS bearing pointers

It is important to note that estimated navigation data supplied by the system in DR Mode may become

increasingly unreliable and must not be used as a sole means of navigation. Refer to the Flight Management

Section for more information on DR Mode
