	Ultralife Powers ELTs - Ultralife Batteries, Inc. \| Application Stories
		An Emergency Locator Transmitter (ELT) is a radio-frequency transmitter that generates a signal to assist in search and rescue (SAR) for missing aircraft.
		In theory, an ELT is activated when subjected to the forces of a crash impact, or manually by survivors.
		The international group responsible for monitoring and locating ELTs via satellite has announced a 9-year phase-out of the older ELT program, to be completed in early 2009.

		The primary difference between ELTs and EPIRBs is how they are automatically activated: an ELT is automatically activated when it is subjected to a sudden physical shock (i.e., during a plane crash), and an EPIRB is automatically activated when it is inverted (i.e., when a boat capsizes) or gets wet (i.e., when a boat sinks).
		When an ELT or EPIRB is activated, there are essentially two ways for a response to be initiated: either someone hears it, or it is heard by an orbiting satellite.
		Any given spot is overflown by one of the satellites an average of once every couple of hours, though the period between passes over a given spot is highly variable because of the particular satellite orbits; it might be ten minutes between one pass and the next, then 4 hours until the one after that.

		On September 15, 2003, an agent of the Commission's Detroit Office investigated an activation of an Emergency Locator Transmitter (``ELT'') transmitting on 121.5 MHz and found the source to be an ELT aboard your aircraft (N6134T) located at Earl's Spray Service, Inc., 2530 Redstone, Breckenridge, Michigan.
		Type A2A, A3E or A3N emission may be employed, except in the case of emergency locator transmitters where A3E, A3X and N0N are permitted.'' The transmissions from your aircraft's emergency locator transmitter were not of a survival nature and were not permitted.
		47 C.F.R. § 87.193: ``Transmissions by emergency locator transmitters (ELTs) are intended to be actuated manually or automatically and operated automatically as part of an aircraft or survival craft station as a locating aid for survival purposes.'' The transmissions from your ELT were not survival purpose transmissions.

	The Need for ELTs in Transport-Category Aircraft
		Emergency services took 14 minutes to locate the crash and 20 minutes to reach it—they first drove to the wrong end of the airport and saw nothing, then went back the other way until they found the airplane.
		Section 44712(a) states: "…an emergency locator transmitter must be installed on a fixed-wing powered civil aircraft for use in air commerce." However, Section 44712(b) states that (a) does not apply to "aircraft when used in scheduled flights by scheduled air carriers holding certificates issued by the Secretary of Transportation…."
		As early as 1974, ALPA recommended that ELTs be installed on all air carrier aircraft and that direction-finding instruments be installed in airport emergency equipment.

	Congressman Christopher Shays -- Fourth District, Connecticut
		I am pleased the Conference Report to H.R., the Aviation Investment & Reform Act for the 21st Century (AIR-21) included Emergency Locator Transmitter (ELT) provisions from H.R., which I reintroduced along with the rest of the Connecticut Congressional Delegation and Congressman Neal of Massachusetts on January 6, 1999.
		H.R., to require ELTs on fixed wing aircraft, with a few exemptions, including planes used by manufacturers in development exercises, agricultural crop planes, acrobatic show planes and large commercial planes which already have on-board technology to be quickly located.
		ELTs play a vital role in search efforts, where timing is so critical in any rescue mission.

	The NW ELT Team
		This device was designed to emit an emergency signal to satellites and SAR personnel in times of distress.
		The NW ELT Team was founded and incorporated in 1983, by a group of dedicated individuals who perceived a specific need within the Search and Rescue community - that of electronic, radio-direction finding.
		NW ELT is continually looking for dedicated personnel to assist us in fulfilling our volunteer mission of answering "the call to action".

	Chapter 10 Section 2 Emergency Assistance
		When the ELT signal strength indicates the signal may be emanating from somewhere on an airport or vicinity thereof, notify the on-site airway facilities personnel and the Regional Operations Center (ROC) for their actions.
		When the ELT signal strength indicates the signal may be emanating from somewhere on the airport or vicinity thereof, notify the on-site airway facilities personnel and the ARTCC for their action.
		Depending on the nature of the emergency, certain weather phenomena may deserve weighted consideration when recommending an airport; e.g., a pilot may elect to fly farther to land at an airport with VFR instead of IFR conditions.

	First COSPAS-SARSAT 406 Mhz Emergency Locator Transmitter Registered at the United States Mission Control Center (Site not responding. Last check: 2007-10-09)
		The first COSPAS-SARSAT emergency locator transmitter (ELT) using a frequency of 406 Megahertz for voluntary use aboard aircraft was registered on Aug. 24 with the National Oceanic and Atmospheric Administration.
		The ELT is registered to E. du Pont de Nemours & Co. of Wilmington, Del. The ELT is one of ten the company's aviation division is installing aboard its corporate aircraft.
		ELTs were initially intended to activate in a crash to alert overflying aircraft which would alert search and rescue (SAR) authorities, and also provide a homing signal to locate the crash site.

	Distress signal - Wikipedia, the free encyclopedia
		The civilian aircraft emergency calling frequency is 121.5 MHz.
		Aircraft can also signal an emergency by setting one of several special transponder codes, such as 7700.
		The recognised mountain distress signal is six blasts on a whistle, or six flashes of a light, in succession followed by a one minute pause and repeated until you get a response (three blasts or flashes is the appropriate response).

	The 406Mhz ELT
		We also discussed some of the problems associated with this ELT such as containing a transmitter that is prone to drift off frequency and a false alarm rate of 95.7% along with the whippy 100mW transmitter.
		One of the requirements of the ELT is it must automatically activate and transmit a homing signal if the aircraft hits the ground somewhat harder than normal.
		During transmission, the 406 ELT will transmit digitally an encoded message which provides information such as country of origin, tail number of aircraft, aircraft type, emergency contact, serial number of the ELT and (with the proper options) position data derived from an internal or external navigation receiver.

		The Emergency Locator Transmitter (ELT) is a 1970 congressional imposed device, which because of technical deficiencies has been unable to perform adequately.
		In 75% of the accidents where an ELT transmission was required the ELT failed to operate.
		The ELT must be replaced as placarded on it by date of 1/2 battery life followed by AandPs signature.

		The ACK ELT comes with two antennas. One antenna mounts to top of the airframe, the other antenna is portable that you would carry in the cockpit.
		The cockpit annunicator has a Red LED that flashes anytime the ELT is in operation.
		The advantage of this is the pilot knows anytime the ELT goes off. The ELT will go off anytime you press the "On" button in the cockpit or turn on the "On" switch on the ELT. Also the ELT will activate anytime the acceleration exceeds 3.5 feet per second.
