DISPLAY SYSTEM REVERSIONARY MODES

EFIS Reversionary Modes

EFIS 1 (PILOT NORMAL) FAILURE
A failure of EFIS 1 (or its interface) is annunciated in one of the following
ways:
D
X on the pilot PFD
D
X on the MFD
D
X on both the pilot PFD and MFD.
To recover from this failure, turn the MFD mode knob from NORM to the
SG2 position. The No. 2 IAC will then drive all three display units.
EFIS 2 (COPILOT NORMAL) FAILURE
A failure of EFIS 2 (or its interface) is indicated with an
PFD. To recover from this failure, turn the MFD mode knob from NORM
to the SG1 position. The No. 1 IAC will then drive all three display units.

Display Controller (DC) Failures

If either display controller fails, its respective symbol generator
automatically bypasses the DC and reverts to its on–side sources. That
is, if the pilot's DC fails, the pilot's symbol generator reads MADC1,
NAV1, VOR1, and VG/DG1. If the copilot's DC fails, the copilot's symbol
generator bypasses DC2 and reads directly from MADC2, NAV2,
VOR2, and VG/DG2. In either case, the following functions are
inoperative:
D
Course select
D
Heading select
D
Altitude select
D
All flight director modes
D
MFD menu (normal, pilot's side).
