Abstract
An improved D.C. power supply for an emergency locator transmitter ELT mounted on an aircraft that does not require lithium batteries but instead uses conventional alkaline batteries in conjunction with a supercapacitor network to provide a reliable power source even when the ELT that is airborne is subjected to extreme cold temperatures that can affect the alkaline battery operation. Alkaline battery pack with a 12 V output is connected to a supercapacitor network board. The supercapacitors are charged when the ELT is activated ON using the comparator network.
