FAA approval for new ELT options for experimental and GA aircraft

ACR Electronics has received FAA approval for several new configurations of its ARTEX ELT 345 Emergency Locator Transmitter, including multiple antenna and remote switch options.

Now approved with a 15-inch antenna and a new two-wire slim-line remote switch, the ELT 345 is available in three different retrofit configurations featuring flexible options that allow for easier and less expensive installations on experimental and general aviation aircraft, according to company officials.  

The ARTEX ELT 345 transmits on 406 MHz and 121.5 MHz frequencies, providing pilots with an emergency distress beacon that maximizes frequency stability and power while incorporating a built-in GPS navigational interface, company officials explained. 

Utilizing the three Cospas-Sarsat Satellite systems, the GEOSAR, LEOSAR, and the new MEOSAR constellations, the ARTEX beacon provides search and rescue forces around the world with the user’s ELT emergency distress message and location in less than three minutes, officials add. 

Each of the three kit options features a two-wire remote switch, coax cable, and antenna, along with the ELT 345 beacon and installation kit.

The primary difference between the kits pertains to the antenna and/or switch offering. The most economical option features the standard 23.5-inch black whip antenna and standard two-wire remote switch.

The newly approved ELT 345 kits include a lower profile 15-inch black whip antenna, designed for installations where a shorter form factor is required. 

Lastly, the new slim-line remote switch works best for ACK and Ameri-King ELT replacements as it requires no modification to the switch panel cut-out when replacing a legacy phone cord style switch. As an added benefit, the slim-line switch requires no batteries and operates using two-wire connectivity for dependable cockpit panel operation, company officials said.

Features and specifications include:

• Single antenna output for emergency transmission on both 406 MHz (Cospas-Sarsat) and 121.5 MHz (local Search & Rescue) frequencies
• Enhanced position accuracy within 100 meters through built-in GPS interface
• Encoded digital message broadcasts aircraft identification/registration and provides access to owner/emergency contact details
• Stainless-steel mounting tray is designed for increased stability in compliance with current FAA guidelines
• The ELT and installation can be tested with a satellite-based online confirmation test via ARTEX’s proprietary satellite testing service 406Test.com (available in North and South America)

ARTEX ELTs are made in the U.S.A. and exceed government and regulatory certification and quality standards, company officials add.
