LIST OF ACRONYMS, ABBREVIATIONS AND DEFINITIONS
Term Definition
AC Advisory Circular –Federal Aviation Administration (USA) bulletin with special information.
For the purposes of this document, the acronym AC does not refer to electrical alternating
current.
AWG American Wire Gauge - An electrical wire diameter standard. Look for this acronym in front
of or following a wire size number.
BNC CONNECTOR A coax cable connector having 50Ω impedance and used for RF signal connections.
CAR Canadian Aviation Regulations –The rules and regulations governing the manufacture,
certification, operation, maintenance and alteration of aircraft in Canada.
CFR Code of Federal Regulations –The general and permanent rules published in the Federal
Register by the executive departments and agencies of the Federal Government. Title 14,
“Aeronautics and Space”, contains the FARs.
CONTAINER The term “Container”, within the context of this document, refers to a device designed to
suppress RF signals, such that the broadcast of an ELT placed in the container cannot
reach the SAR satellite system.
COSPAS-SARSAT The international search and rescue consortium, that governs the international
satellite-based search and rescue distress alert detection and information distribution
system. For a complete description, go to the official web site for the International
COSPAS-SARSAT Program, http://www.cospas-sarsat.int/en/
D-SUB CONNECTOR D-type (shaped), subminiature connectors –connector for low voltage/current signals and
electrical currents.
DER Designated Engineering Representative –An individual qualified and designated by the
FAA to approve, or recommend approval, of technical data to the FAA.
DRIP LOOP Extra wire length used to form a U-shaped bend in a wire or cable. Water or other fluids will
flow down to the bottom of the loop and drip off. Electrical connections are made at the top
of the loop.
ELT Emergency Locator Transmitter –ELTs are installed on aircraft and used to send
emergency signals to the SAR satellite system. The word “Beacon” is associated with these
devices.
EMI Electromagnetic Interference –An undesirable disturbance that affects an electrical circuit
due to either electromagnetic conduction or electromagnetic radiation emitted from an
external source; also called radio frequency interference or RFI.
EUROCAE European Organization for Civil Aviation Equipment –EUROCAE documents is widely
referenced as a means of compliance to European Technical Standard Orders (ETSOs) and
other regulatory documents.
FAA Federal Aviation Administration –The United States government agency for aircraft safety
and regulation.
FAR Federal Aviation Regulations –The rules and regulations governing the manufacture,
certification, operation, maintenance, repair and alteration of aircraft in the United States.
FORM 337 FAA Form 337 is required when a major repair and/or major alteration is performed on an
aircraft. Refer to FAR, Part 43, Appendix A and the definitions of Major Repair/Alteration
contained in FAR, Part 1, for guidance.
FSDO Flight Standards District Office –FAA district offices responsible for aircraft certification,
operation, maintenance and modification issues, approvals and enforcement.

G-SWITCH Velocity switch that detects sudden deceleration and is used to automatically activate an
ELT; may also be referred to as a “crash sensor”.
LED Light Emitting Diode –Semiconductor device that emits light when current is passed
through it. Usually used as a status or warning indicator.
MIL The three-letter acronym that stands for “Military” and precedes military specifications and
standards numbers (e.g., MIL-W-XXXX would indicate a wire specification and
MIL-STD-XXXX would indicate a standard).
P/N Part Number –Refers to an ACR part number, unless otherwise noted.
PLUG The term “Plug”, within the context of this document, refers to the male half of an electrical
connector.
RECEPTACLE The term “Receptacle”, within the context of this document, refers to the female half of an
electrical connector.
RF Radio Frequency –The range of electromagnetic radiation that constitutes the radio
spectrum and corresponds to the frequency of alternating current electrical signals used to
produce and detect radio waves.
RTCA Radio Technical Commission for Aeronautics –Organization that makes recommendations
for airworthiness; refer to http://www.rtca.org/aboutrtca.asp for more information.
RTV A rubbery silicon-based adhesive typically used to prevent vibration problems and water
intrusion.
SAR Search and Rescue
SCREEN ROOM Refers to a room designed to block RF signals, such that the broadcast of an ELT placed in
the screen room cannot reach the SAR satellite system.
SERVICE LOOP A length of wire or cable at the connection point, of sufficient length to allow a component
to be withdrawn from its mounting position and disconnected from its associated wiring.
TETHER A cord or similar device that anchors something movable to a stationary point or anchors
two items together, such that they cannot become separated beyond the length of the
tether.
TSO Technical Standard Order –A TSO is a minimum performance standard issued by the FAA
for specified materials, parts, and appliances used on civil aircraft.
UTC Coordinated Universal Time –A time standard based on International Atomic Time. UTC is
the time system used in aviation and is often associated with Greenwich Mean Time (GMT)
and/or “Zulu” time.
VHF Very High Frequency –The 30 MHz to 300 MHz radio frequency band.
VSWR Voltage Standing Wave Ratio –The ratio of the amplitude of a partial standing wave at an
antinode (maximum) to the amplitude at an adjacent node (minimum), in an electrical
transmission line. An ideal transmission line would have a VSWR of 1:1.
