The ACR ARTEX ELT 4000: Costs, Benefits, and Replacements

Aircraft emergencies may be the furthest thing from your mind, but it is important to be prepared. Having an emergency locator transmitter (ELT) onboard is crucial in case search and rescue teams need to locate the aircraft. In this article, we review the ACR ARTEX ELT 4000 and inform you of its benefits, including cost savings and encoded beacon signals, and when to test, replace, and register the ELT to ensure preparedness and safety.  


What is the ACR ARTEX ELT 4000?

The ACR ARTEX ELT 4000 is a transport-grade emergency locator transmitter (ELT) utilizing alkaline batteries. ELTs are distress radio beacons that send digital 406 MHz signals to Cospas-Sarsat satellites and alert search and rescue (SAR) teams of the aircraft’s GPS coordinates. An analog 121.5 MHz homing signal further assists SAR teams in locating the aircraft. The ELT 4000 can send a distress signal for a minimum of 24 hours at 406 MHz and 48 hours at 121.5 MHz. 

How Much Does the ARTEX ELT 4000 Cost?

The ELT 4000 installation kits range in price between $6,000 to $10,000. These kits include the necessary accessories for installing the system, plus the antenna and remote switch. 

Different aircraft applications may require an additional antenna, purchased separately. 

Benefits of ACR ARTEX ELT 4000

Cost Savings

Over the course of ownership, buyers can expect approximately 25% or more in cost savings with the ELT 4000 in comparison to legacy ELT systems and similar lithium battery ELTs. 


The ELT 4000 is exempt from FAA Lithium Special Conditions requirements and hazardous shipping, which further contributes to cost savings.  

Comparable to Lithium Battery ELTs

Although the ELT 4000 utilizes alkaline batteries, it meets the same Cospas-Sarsat requirements as lithium battery ELTs and has the same expected 5-year lifespan. 

Global Coverage and Security

The ELT 4000 offers global coverage via 406 MHz satellite-signaling beacons. Further, digital message broadcasts are encoded for greater security. 

Multiple Approvals

The ELT 4000 is Cospas-Sarsat approved and has approval from the FAA, EASA, TC, JTAB, CAAC, and Industry Canada.

Easy Installation

ARTEX features a single output ELT using one radio frequency (RF) connector to a single cable that connects to ARTEX single input antennas for easy installation. ELT 4000 has a built-in navigation interface, which can receive position data from an onboard GPS/FMS (flight management system) for increased location accuracy to within 100 meters.  

The ELT 4000 is TSO-approved for retrofit with legacy ARTEX B and C Series ELT switches, antenna systems, and mounting tray assemblies. 

Further, the ELT 4000 can be installed on a wide range of regional, commercial, corporate, helicopters, and some military aircraft. An STC is available for installation on Boeing 737 commercial jets for upgrading from the ARTEX B406-4 to the ELT 4000.  


When to Test Your ARTEX ELT 4000?

The beacon owners’ manual recommends that self-tests be performed each month and before extended trips to ensure the beacon is working properly. If the self-test fails, you must contact the manufacturer or an authorized service agent for further instructions and service.  

When to Replace the ARTEX ELT 4000 Battery?

The ELT 4000 alkaline battery requires replacement every 5 years, and an expiration date label can be found on every beacon. The battery must also be replaced if the beacon accidentally activates.

How to Register the ARTEX ELT 4000?

The ELT 4000 beacon must be registered with your country’s National Authority, either at the time of purchase or installation. The registration includes identification and contact information for SAR teams to assist in locating the aircraft and providing aid. Registration is valid for 2 years and must be re-registered upon expiration.
