Smaller and Lighter ELTs with TSO C142b authorized batteries

The pending end of support for the further repairs on the legacy RESCU 406AF/AFN and RESCU 406SE products coming December 2021.  Spare sales for these legacy products have ended.  Honeywell no longer produces them or allows replacements of batteries in repairs.

Trade-in and upgrade your existing Emergency Locator Transmitter (ELT) devices for next-generation ELTs and enjoy significant discounts on the list price. 


Honeywell’s RESCU 406 Automatic Fixed Navigation (AFN2) and Portable RESCU 406SG deliver the best value for aircraft operations with their industry leading lithium battery design, higher reliability with Mean Time Between Failure (MTBF) of 98K+ hours, and improved performance.

  • Honeywell ELT battery is currently the ONLY one that meets the EASA CRI: 
    • Next generation (Rescue 406AFN2 and RESCU 406SG) ELTs have new batteries that fully meet the FAA special conditions and EASA Certification Review Item (CRI) for non-rechargeable lithium batteries
  • Next generation batteries have achieved CAN-TSO approval of FAA TSO-C142b (issued on 26 March 2018) which require lithium cells and batteries, intended to provide power for aircraft equipment, meet the minimum performance standard (MPS) qualification and documentation requirements as per RTCA DO-227A, Minimum Operational Performance Standard (MOPS) for Non-Rechargeable Lithium Batteries
  • Next generation ELT’s have a ~40% size/weight reduction
  • Next generation ELT’s incorporate battery usage monitor as part of self-test

We strongly recommend that operators upgrade at the earliest opportunity to take advantage of this limited period trade-in-offer and to improve safety further.
