Enterprise-wide Benefits of RFID
By working together on these non-competitive standards
initiatives, both Boeing and Airbus benefit by avoiding
conflicting requirements with mutual suppliers and customers
and delivering products and services which create best value.
Customer and Supplier Benefits Production System Benefits
reduces inventory control and
provisioning costs
accurate configuration control and
repair history
reduces warranty claim processing costs
regulatory agency compliance monitoring
part installation and removal time tracking
accurate and efficient spare parts pooling
identification of rogue parts
accurate flight hours tracking by part
reduces parts receiving costs
eliminates data entry errors
provides accurate
“as delivered” configuration
improves part location tracking
reduces risk of unapproved parts
timely problem resolution

Industry Position on Passive RFID
Because passive RFID devices:
■ Have no on-tag power source and no active transmitter, and
■ Perform a ground operated, non-essential function, and
■ Are not potential sources of interference or susceptibility and
■ Are FCC-certified for unlicensed use.
Regulatory agencies have agreed that passive RFID devices
comply with applicable regulations and do not impact form, fit, or
function of installed systems and equipment.

Federal Aviation Regulations (FAR)
■ Radio and electronic equipment, controls, and wiring
must be installed so that operation of any one unit or
system of units will not adversely affect the
simultaneous operation of any other radio or
electronic unit, or system of units...
■ The occurrence of any failure condition which would
prevent the continued safe flight and landing of the
airplane is extremely improbable, and…

Considerations for Deploying RFID on Parts
■ Line replaceable
■ Repairable
■ Recommended as a spare
■ Frequency of removal
■ Spares price
■ Dispatch criticality
■ Life-limited or time-controlled part
■ Emergency equipment

FAA Policy: RFID Conditions for Use on Civil Aircraft
1. Must operate in the passive only mode.
2. Must not radiate (backscatter) harmonics above a level of 35dBuv/m.
3. The frequency assignment must remain outside of the published aviation frequency bands.
4. Harmonic frequencies do not impinge upon any assigned aviation communication or navigation frequency.
5. Use of passive only devices is restricted to ground operations only.
6. Each item of installed equipment must function properly.
7. Designed to operate in an aircraft environment with robust radio frequency stability.

Checked as “OK” or “NG”. Generators
replaced 19 months prior to expiration.
20% loss of product life-cycle yield and
greater consumption of product.
After
8.5 labor minutes – 99% reduction
8.5 minutes – 98% reduction
80% reduction, forward deployed to line
stations and managed as “just-in time.”
All transactions captured in front-end
database. As-flying configuration
management allows for generator
replacement in weeks or days before
expiration.
20% recovery of product
life-cycle yield, decrease in product
consumption.

Future RFID Outlook for Aerospace and Defense
■ Purely passive integrated circuit designs will provide extended user memory beyond 64 KB.
■ Data transfer rates will increase dramatically and reach Megabytes per second.
■ Innovative antenna designs will increase range and performance.
■ Active tags incorporating onboard wireless sensor networks will proliferate aerospace products.
■ Prices for commercially available off-the-shelf readers will decrease due to economies of scale.
