Efis Reversion Controller - Honeywell PRIMUS 1000 Pilot's Manual

EFIS Reversion Controller

EFIS reversion functions retain usable flight displays even after multiple
failures. For example, if a PFD tube fails, its data can be displayed on
the MFD, or data from a failed symbol generator can be replaced by the
remaining good symbol generator.
Heading, attitude, and air data are controlled using the reversionary
switches shown in Figure 3–18 and described below.
