DU-880 Display Unit
Leading Particulars
Table 6-1
The DU-880 Display Unit is a large format 8 x 8-inch display which uses a
high resolution color CRT to display attitude, heading, altitude,
airspeed, vertical speed, air data parameters, navigation information,
weather mapping, engine data, crew alerting information, and system
pages.
The six-unit configuration is arranged in the cockpit as shown in
Figure 6-2 with the primary display function identified. The displays
are interchangeable except when used as a primary flight display (PFD)
and an inclinometer is attached to the bezel.
In addition to the circuit
breaker panel, power may be removed from the display system by the
display power panel located in the overhead on the pilot’s side of the
cockpit.
This panel is shown in Figure 6-3. The leading particulars of
the DU-880 are listed in Table 6-1. The electronic display system
operation is described with reference to Figure 6-4. Figure 6-5 contains
a block diagram of the DU-880.
Each of the six display units interfaces with the symbol generators
through a I-MHz serial digital bus.
Each display unit has three l-MHz
serial digital bus inputs, each input is connected to one of the three
symbol generators. In addition, each display unit (C)U)has a WX bus
input, however, only the two navigation displays (DUS 2 and 5) use this
input, which is connected to all three symbol generators.
Bus source
select discretes are input to the display units from the reversionary
controller to select which SG will drive a particular DU.
