Introduction
The requirements for RFID tags to be used in the aerospace industry are very different from non-aviation uses. The
parts identified by the RFID tags are high value items, which are often used for ten years or more. Reading and
writing across a moderate distance, and over the life-spans of these tagged-parts, is expected to improve data
accuracy and cost savings. Furthermore, the aerospace industry is subject to unique considerations regarding
qualification, regulations, and safety, which are enforced by aviation authorities such as the EASA, FAA, etc.
These requirements, coupled with the relatively low manufacturing volumes, will drive up the per-part cost of
tags developed for the aerospace industry. This will generate the need for a set of RFID tags specifically
designed for use on aircraft. Adherence to this European Standard will decrease the development cost of these
low-volume, high-capability RFID tags.
1 Scope
The scope of this European Standard is to:
• Provide a requirements document for RFID Tag Manufacturers to produce passive HF tags for the
Aerospace industry.
• Identify the minimum performance requirements specific to passive HF tags used on aircraft parts, accessed
only during ground operations.
• Specify the test requirements specific to passive HF tags for airborne use, in addition to EUROCAE ED-14 /
RTCA DO-160 latest issue compliance requirements separately called out in this document.
• Identify existing standards applicable to passive HF tags.
• Provide a qualification standard for passive HF tags which will use permanently-affixed installation on aircraft
and aircraft parts.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
AEROSPACE APPLICATIONS
used on products created for the aerospace industry
3.2
AIRBORNE USE
used on aircraft while in flight—as opposed to Ground Service Equipment, which is used on aircraft, but only
while, the aircraft is on the ground
3.3
ATA: AIR TRANSPORT ASSOCIATION
airline trade association whose purpose is to foster a business and regulatory environment that ensures safe and
secure air transportation. ATA coordinates standards-creation in support of this purpose.
3.4
BACKSCATTER
the Radio Frequency (RF) energy reflected by the tag to transmit information to the interrogator. The RFID tag’s
chip and antenna modulates the incident energy and reflects it back (same orientation but opposite direction).
Backscatter is what the interrogator device “reads.” An inert piece of aluminium will reflect RF energy, but in the
absence of modulation, it is “reflection”, not “backscatter.”

3.5
BAP
Battery Assisted Passive — RFID tags that have an on-board battery to power the electronics in the tag,
minimizing the power required from the interrogator Radio Frequency Beam. They backscatter like a passive
UHF tag only when they are interrogated. BAP tags have greater read ranges than purely passive tags.
3.6
BAR-CODE
a standard method of identifying items based on lines of varying widths and spacing that are visually read by a
scanner
3.7
BLINK RATE
the rate at which an active Chip/Tag sends out s signal to look for, this can be adjusted from hours to seconds
depending on the application and desired battery life of the RFID tag
3.8
CHIP
“chip”, or “microchip”, refers to integrated circuits, or ICs. This is the “brain” of the RFID tag. RFID chips
modulate reflected RF power to transmit data back to an RFID reader, or “interrogator”.
3.9
EASA
European Aviation Safety Agency
3.10
EIRP
Equivalent Isotropically Radiated Power — the amount of power that would have to be emitted by an isotropic
antenna (that evenly distributes power in all directions and is a theoretical construct) to produce the peak power
density observed in the direction of maximum antenna gain
3.11
EUROCAE
European Organisation for Civil Aviation Equipment
3.12
FAA
Federal Aviation Administration — the airworthiness and aviation authority in the United States of America
3.13
FAR FIELD ZONE: D
D > (2.a) /l
where
D far field zone;
a maximal size of the antenna;
l wavelength = c/f.
3.14
HF
High Frequency covers the 13,56 MHz frequency band
3.15
HUMAN-READABLE
human-readable refers to a representation of information that can be naturally read by humans. In most
contexts, the alternative representation is data primarily designed for reading by a machine, e.g.,
scanner/computer/etc.
3.16
INLAY
the RFID inlay is comprised of four primary components: chip, attachment harness, antenna, and substrate. An
antenna is either laid or printed on a substrate material (typically a polymer). Designers create antenna patterns
to satisfy specific performance requirements. The “chip” is harnessed to the antenna pattern so that the contacts
on the chip make contact with the appropriate legs of the antenna.
3.17
INTEGRATED CIRCUIT
(IC)
see “Chip”
3.18
INTERROGATOR (READER/WRITTER)
Radio Frequency device whose purpose is to read data from RFID tags or write data to them. There exist both
hand-held versions and desk-top versions. Hand-held interrogators have battery power and on-board
modulator/demodulators to allow reading permanently-affixed tags while moving past them, and are usually
limited in power output.
3.19
ISO: INTERNATIONAL ORGANIZATION for STANDARDIZATION
an international association that manages the process of setting global standards for communications and
information exchange
3.20
LABEL
label is comprised of three primary components: an RFID inlay, an outer surface (often used for printing), and a
bonding surface. Other layers and components are often added to provide addition features and performance to
the label.
3.21
LRU
Line Replaceable Unit — a component that can be pulled off the aircraft by “line” mechanics and replaced with
an identical part, as opposed to requiring depot-level or manufacturer’s AOG (airplane on the ground) teams to
do maintenance in situ
3.22
MACHINE-READABLE
the term machine-readable (or computer-readable) refers to information encoded in a form which can be read
(i.e., scanned/sensed) by a machine/computer and interpreted by the machine's hardware and/or software.
Machine-readable technologies include optical character recognition (OCR) and barcodes.
3.23
PASSIVE
the most common RFID tags, in which a interrogator transmits an energy field that “energizes” the tag and
provides the power for the tag to backscatter
3.24
RANGE
the straight line distance between two articles, e.g., an RFID tag and an RFID interrogator
3.25
RANGE, MINIMUM R
