DESCRIPTION AND
OPERATION
The Electronic Display System shown in Fig-
ure 16A-10 is comprised of three subsystems.
The Pilot's Display System, the Copilot's Dis-
play System and the Multifunction/Weather
Radar System. The pilot's and copilot's sys-
tems are identical, with both providing ADI
and HSI information to the flight crew. The
Multifunction/Weather Radar display system
provides long and short range navigation maps,
checklists and weather radar, and serves as a
data source and back-up symbol generator for
both the pilot's and copilot's display system.
All five electronic displays are identical and
interchangeable. A conventional slip/skid in-
dicator is attached to the top display to be used
in conjunction with the attitude presentation. The
electronic displays use a combination of man-
ual and photoelectric dimming to enable clear
readability under varying light conditions.
The pilot's and copilot's system contain iden-
tical symbol generators which are the focal
point of information flow in the systems. The
symbol generator's major task is to convert the
information present at its inputs to video and
deflection formats required by the display
units to form the ADI and HSI displays. The
MFD symbol generator provides the naviga-
tion maps and checklists for display on MFD
display, and also serves as a backup symbol
generator for either side.
The pilot's and copilot's display system both
contain a display controller and a source con-
troller. The display controller provides the
means by which the pilot can control the dis-
play formatting, such as full or partial com-
pass display or single cue or cross pointer
display. The display controller is also used to
select navigation and bearing sources for dis-
play. Auxiliary switches in the cockpit are
used to select alternate heading and attitude
sources, EFIS air data sources, and to select
reversionary mode. The MFD system also con-
tains two controllers. The MFD controller,
provides for the selection and control of the
MFD formats, modes, waypoint designator,
and checklist. The weather radar controller
selects the radar modes and adjustable quan-
tities which may then be displayed on either
the MFD or EHSI.

Each Side)
The Display Controller (Figure 16A-11) pro-
vides the means by which the pilot can con-
trol the EFIS display formatting. Also included
on the Display Controller are the bearing se-
lect knobs. The following paragraphs describe
the controller functions:
FULL/ARC Button
The FULL/ARC button is used to change the
EHSI display from full compass to partial
compass format. In the full compass mode,
360' of heading are displayed. In the partial
compass mode, 90° of heading are displayed.
Successive toggling of the FULL/ARC button
changes the display back-and-forth from the
full compass to the partial compass display.
