> Condition-monitoring
Asset protection. Fuel conservation. Customer satisfaction.
Hard-lifing an engine is anathema to us.
That’s why engine maintainers and aircraft operators use our health management
tools to plan systems maintenance and avoid unscheduled grounding of aircraft
and lengthy manual diagnostics.
Meggitt is famous for the condition-monitoring systems developed for the Airbus
A380 and Boeing’s Dreamliner but its product ranges are well within reach of
corporate aviation—and just as relevant.
> A fleet of multi-million dollar aircraft is worth protecting, whatever its size.
> You’ve got executive schedules to honor, so your aircraft must always
be ready to go.
> Discerning customers expect a high degree of traveling comfort so
vibration must be minimal.
> And when engines run cleanly because they are well-maintained,
fuel bills go down.
Meggitt’s scaleable, modular condition-monitoring products can be added or
integrated. All improve the economics and the luxury passenger features of any
aircraft operation.
Broadband monitoring
Selected by Dassault for the Falcon 7X and 2000 EX,
Gulfstream for the 150 and 200 and Bombardier for
the Learjet 45 and 60, this broadband engine
vibration monitoring unit is ideal for business jets.
Multi-channel processing meets the minimum
regulatory requirements for vibration monitoring
with full engine-to-engine segregation, very high
reliability, lightness in weight and low cost.
The concept can be adapted easily for single, twin
or triple engine vibration processing.
One card, all the functionality
This integrated engine vibration monitor, designed
for the Hawker 4000 Horizon, integrates all the
functionality needed for airborne vibration
monitoring onto a single plug-in board.
Compact and easy to replace, the system features
on several regional and business jets including the
Gulfstream 350, 450 and 650 and, through Honeywell’s
EPIC system, the Embraer 170 and 190 family.
Many of Meggitt’s vibration monitoring systems incorporate “cold fan trim
balance” which gathers data during an ordinary commercial flight and
provides the part numbers and position of correction weights necessary to
address unbalanced conditions. Maintenance personnel fit the prescribed
weights on landing with minimal disruption compared to traditional
on-ground balancing methods.

> Avionics
Integrated standby instrument
This new solid-state instrument measures and
displays aircraft attitude and air data.
Essential dynamic flight information is provided in
a single 3ATI format displaying attitude, altitude,
airspeed, heading and navigation data.
The system can also be configured to display
information from remote systems including air
data probes or air data computers, attitude
heading reference systems and magnetometers.
Simplifying mechanical and visual complexity, the
design of these instruments is based on the common
approach to control and appearance that
characterises all Meggitt’s engine and flight displays.
Magnetometer heading sensor
A standalone microprocessor-based unit providing
digital heading data output in ARINC 429 format at
low or high speeds.
Accurate digital output of heading replaces
fluxgate compasses and enables simpler
interfacing with modern aircraft systems and
displays.
Heading is sensed from the earth’s magnetic field.
Two-axis information comes from the three-axis
magnetometer used with a two-axis tilt sensor. The
units are housed in non-magnetic cases, compatible
with existing fluxgate sensor installations.
Air data unit
Two solid-state pressure sensors measure aircraft
pitot and static pressures. Sensor outputs are
provided in ARINC 429 format as raw pressure data
for secondary and standby systems.
Lightweight and extremely robust, the unit can be
located in pressurized or unpressurized areas of an
airframe.
Intelligent reading for pilots
As every pilot knows, the effects of sensory overload in extreme conditions can be significant. That’s why the design
of our flight deck instruments—for navigation, engine, fuel, and flight data—focuses on human factors and the
assimilation of critical information under stress.
We simplify mechanical and visual complexity by employing compact, highly intuitive and optically-brilliant displays,
replacing and integrating the function of multiple electro-mechanical gauges in single, three-inch instruments.
Meggitt has customized and certified secondary flight display systems for more than 40 different aircraft types—
with equally diverse performance criteria.
Electronic engine displays
Pilots prefer these easy-read, highly-intuitive
displays, which replace and integrate
electromechanical gauges showing torque, speed,
exhaust gas temperature and fuel data.
Engineers prefer them because they can use the
monitoring data from multiple preceding flights to
improve performance, reliability and operating cost.
For fixed and rotary wing, these three-inch
indicators feature high-quality engine monitoring
displays with reversionary capability.

> Smart sensing
One supply chain solution
Because today’s gas turbine engines need a wider range of sensors than ever to hone performance
and conform to environmental regulation, engine manufacturers are turning to suppliers who can
integrate the supply of these critical system components.
Meggitt measures air temperature, fluid temperature,
shaft speed, vibration, oil level, oil debris, actuator
position, oil pressure, fuel press and fuel flow, combining
these in-house capabilities with the technologies of
carefully selected sub-tier partners where necessary.
We supply Rolls-Royce with the sensor and ignition
systems for the BR725 engine—the exclusive power
plant for the new Gulfstream G650 business jet—and
multiple sensors to Hamilton Sundstrand for Pratt &
Whitney’s revolutionary PurePower™ PW1000G geared
turbofan engine.
Mass flow meter
Designed to be even more reliable, smaller and economical to run, Meggitt
has added this new mass fuel flow meter to its sensing and ignition packages.
Utilising a motorless design, the Meggitt flow meter is a fluid-driven, true
gravimetric device that measures fuel flow directly by the angular
momentum principle. The flow meter produces a start and stop electrical
pulse. The differential between these two signals represents the mass flow
of the fluid.
> Flow rates up to 6000 pph – the highest in its category
> Low profile design requiring less mounting space
> Accuracy >1% over critical flow range
> Improved electrical performance
> Approved for extreme electro-magnetic interference
> Requires no input power
Meggitt’s fluid gauging solutions are based on 60 years in mission-critical fuel and oil measurement.
> Measuring fuel burn rates accurately even at cruise
> Helping our customers meet environmental regulations and monitor engine health
> Concentrating data from individual sensors into avionics systems, saving space, weight and design,
installation and maintenance costs
> Locating faulty fuel probes instantly with digital self-diagnostic solutions
Mounted directly in main engines, accessory gearboxes and APU oil
tanks, uses capacitance or magnetic float and reed switch technology
for high MTBF operations. Highly reliable. No scheduled maintenance
needed. Intermediate case-mounted devices are available for remote
ADD or discrete out-of-sight level sensing.
Fuel flow transmitter
One robust product providing reliable, accurate
volumetric measurement of engine fuel flow from
35 to 2000 pounds per hour at high fuel temperatures.
A “K-factor” scaling resistor allows for sensor
interchangeability.
Chip detector with self-closing valve
Rugged and reliable. Continuously monitoring lube oil
during engine, accessory gearbox and APU operation,
collects ferrous wear material from the lube oil stream
and tells you when you’re ‘making metal’.
Oil quantity and temperature sensor
Signal conditioner and data concentrator
Failsafe fluid measurement
Fan case-mounted oil level sensor
Designed for intermediate case, oil reservoir, or remote mounting,
Meggitt’s oil level sensor replaces sight glass applications where
direct viewing is difficult or impossible. This design provides single
or multiple point level indication using rugged, reliable magnetic
float technology. Switching points and sensing range are
customizable and self-test capability can be incorporated. Level
indication can be via cockpit avionics or a remotely-mounted LED
display to facilitate oil replenishment by ground service personnel.
Processes sensor inputs for linearization, compensation
and digital conversion. Whether a signal conditioner for use
with individual sensors or a data concentrator aggregating
multiple engine and airframe sensors and discrete inputs,
we provide compact, cost-effective and convenient solutions.
Capacitance fuel probe
Measures fuel quantity accurately and dependably using
optimized circuit design and components and the
internal bracket or external flange mounting dictated by
tank design. Consisting of concentrically-mounted
tubes, these probes act like a variable capacitor as the
fuel level in the tank changes over a wide range of fuel
temperatures. No scheduled maintenance is needed.
Systems are certified to FAA TSO C55.
Fluid probe (passive)
Connected to the remote processor unit via an RF cable,
the probe is mounted within the fuel/oil reservoir,
providing the wave guide for the electronic pulses. Can
be top mount-configured using the appropriate flange
interface or designed for internal mounting within the
tank via standard mounting clips.
Fluid probe (active)
An integrated design of wave guide and processing
electronics provides a discrete sensing system. There
are no limitations on wave guide configuration and
standard communications protocols such as CANbus,
ARINC 429, RS232/422 or resistive output are available.
Fluid quantity processor
Accommodating up to six fluid probes, the processor
sends a low-energy signal via an RF cable into the probe
wave guide and measures level via the reflection time of
the pulse from the fluid surface. The processor includes
self-diagnostics and will identify when faulty sensors
need replacing.
System architecture
The systems we have developed and certified for major
players in business aircraft include multiple sensors
per signal conditioner in a multiplexed architecture.
Next generation fluid gauging
Using echoes from high-speed electronic pulses transmitted down a
waveguide extended into the fuel or oil reservoir, the system locates the
fluid-to-air interface and provides the measured level via the pulse’s
return time. With no dependence on fluid characteristics, it can be used
in any fuel or oil and does not require specific calibration unlike existing
gauging technologies.

Passing the flight test
Proven on the composite wings of Boeing’s
Dreamliner, the aerospace community now has
access to the solution we believe will become
essential to testing and developing future
aircraft structures.
With Boeing, Meggitt has devised a Flexible Air Sensing
Technology (FAST), a non-invasive way of calculating
pressure and structural loads in composites without
damaging their integrity—or compromising accuracy.
This revolutionary air pressure
measurement system is designed for
easy, non-invasive installation that will
not affect the integrity of fibre-based
structures. We connect miniaturized and
temperature-compensated sensors,
mounting them on flex circuitry to form a
configurable array and provide data
through network communication
protocols. The flexible circuit design
includes an option for remote sensor
mounting in challenging installation
locations. Previous measurement
systems were limited to invasive cabling,
tubing, signal conditioners and data
acquisition products.

Prized by flight test engineers for their
dependability and technical ingenuity, we
have pioneered sensing solutions for every
major US military aircraft since 1947.
We measure extreme temperature (-269ºC to +650ºC),
extreme acceleration (0 to 200,000 g), extreme pressure
(0 to 30,000 psi) and extreme radiation (1 x 108 rad). Many
of our products have been written into the standards by
which others calibrate theirs.
Measuring a wide variety of performance and safety
features internally and externally, you will find our
products on small single-engine aircraft, large
commercial transports, military jets and space vehicles.
On and off the ground, whether during engine
development or maintenance, flight testing or onboard
engine monitoring, future aircraft safety and optimal
operations depend on the data acquired from our sensors.

Keeping you on your way
Where brakes with ordinary performance stop at around 10 ft/sec2 (0.31 g), many of ours
exceed 14 ft/sec2 (0.44 g). That’s a 40 per cent improvement in stopping performance.
What’s more, with less cool-down time than you’d expect,
our brakes can be ready for departure within just 15
minutes of arrival—the short wait most operators dream of.
Of course, all the brakes in the world won’t give you
optimum brake performance without a high performance
brake control system. Embraer’s Phenoms and Legacy 450
and 500 all feature fully integrated brake-by-wire control
technology—perfected by Meggitt across numerous
programs.
Keeping you in business
Our experience in this demanding high-cycle environment
is unrivalled, which is why we have been able to redesign
the Lear 60XR’s brake to triple the life of the original while

More electric—but not larger
That’s important when you consider that electric brake actuators are bigger and
heavier than hydraulic piston assemblies.
Making them compact
In a little over two years, we achieved a degree of compactness
and efficiency in our electric brake’s electro-mechanical
actuator that the industry took around 70 years to deliver in
hydraulics. This actuator remains one of the most compact, yet
efficient of its kind in development today.
Making history
Meggit’s Ebrake® made history in 2008 with its inaugural test
flight on a Bombardier demonstration aircraft. This was the
first time a full electric braking system was flown successfully
on a commercial aircraft with no hydraulic fall-back.
