Meggitt Avionics’ electronic engine display system (EEDS) is a developed,
military standard, commercial off-the-shelf (COTS) product, comprising
two high technology units from our newest product development
programmes – the engine monitoring display (EMD) and data acquisition
unit (DAU). The system has been specifically designed to replace aged inservice engine stacks with a small, modern, flexible and cost-effective
solutions. Ideal for military and civil, fixed and rotary wing applications,
EEDS features high quality engine monitoring displays, with reversionary
capability, preferred by pilots for easy-to-read highly intuitive design.
The EEDS records engine exceedence data from previous flights, which can
be displayed by the EMDs or downloaded onto a PC. This enables
organisational maintenance engineers to make informed condition based
maintenance decisions, leading to leaner and more cost effective support.

• DAU options for foot or
tray mounting
• Compact and lightweight
system
• Low power consumption
• All solid state design
requiring only 28 VDC
• Passively cooled, low power,
low temperature design
• Software configurable
• Requiring only 5.5” (139.7
mm) behind the panel, the
3ATI instrument can be
installed in the most
restrictive cockpit
• The glass used in the EMD is
high resolution (RGB Stripe),
giving superior contrast and
luminance
• The unit incorporates a frontloaded bezel assembly,
enabling inter-changeability
for multiple applications

Meggitt Avionics
recommends installing two
EMDs per cockpit, one
above the other, as shown.
Installing the EMDs in this
vertical configuration allows
for the most logical
presentation of parameters,
with left and right systems
being instinctively apparent,
providing flight crews with
enhanced readability
without the need for
complex training.
Before
After
• Exceptional sunlight
readability
• High reliability for fewer
unscheduled removals
• Extensive IBIT eases
maintenance and reduces
NFFs
• Reduced repair time
compared to
electromechanical
instruments
• Exceedence monitoring
enables cost effective,
condition based maintenance
• Dual redundancy with
immunity to single point
failures
Data acquisition unit
• In a typical twin-engine
aircraft, between eight and 12
indicators are used per
cockpit to display engine
data. For a fleet of 30 twincockpit trainers, up to 720
engine instruments are
installed, plus spares. The
same fleet of 30 trainers
fitted with EEDS, consisting
of two EMDs per cockpit and
one full redundancy DAU,
gives a comparative LRU
count of only 150 versus 720
The EMD presents engine, fuel and other
aircraft data received via the DAU. The
display format can be tailored to suit
specific requirements such as dials, linear
scales, text or other symbols – mimicking
the layout of the instruments being
replaced. With dynamic use of color and
flexible symbols, the EMD delivers a vastly
improved instinctive pilot interface.
Analog sensor interface complexities are
addressed by the DAU’s modular design,
which includes I/O boards that can be
configured for each application.
• Meggitt Avionics' lightest
EMD weighs a mere 2.5 lb (1
kg) and is some 30 per cent
below its rivals.
• It is night vision goggle (NVG)
compatible
EED can be fully integrated without
changing the aircraft’s existing engine and
fuel sensors. The DAU boasts a dual
redundant design to ensure continuous
availability of engine data should any
single point fail. Even with such extensive
functionality and redundancy, the DAU is
an impressively small unit that can be
comfortably accommodated in most
avionics bays.
