3.2 EIS DISPLAY IN REVERSIONARY MODE

In the event of PFD1, PFD2 or MFD failure, the Display Backup button must be pressed to enter reversionary

(or backup) mode. Reversionary mode is a mode of operation in which all important flight information is
presented identically on at least one of the remaining displays (see Figure 3-12). Transition to reversionary

mode should be straightforward for the pilot, for flight parameters are presented in the same format as in
normal mode (refer to the System Overview for information about display Reversionary Mode).
