AIRFRAME TECHNOLOGY (b), and still others use a combina- tion of both options. Recent feed- back from operators has been very favorable and the occurrence of low battery conditions is no lon- ger an issue. AMT Dr. Dave Vutetakis has a Ph.D. in Concorde RG-380E/44 battery installed in a DHC-8 aircraft. disclosed. Concorde's RG-380E/44 battery is original equipment on this particular turboprop aircraft. From time to time, operators com- plained that the battery would not hold a charge between flights, causing engine start issues. The problem normally occurred on aircraft with low hours per month or when there was a long To remedy the issue, disconnect the battery plug after each flight or connect a maintenance charger when the aircraft is inactive for more than a few days. time between flights. It was sus- pected that a parasitic load was responsible and measurements on several different aircraft con- firmed a drain rate of approxi- mately 16 milliamps. At this rate, the battery capacity would be reduced by 25 percent in 28 days. To remedy the issue, two I D R O options were recommended: a) disconnect the battery plug after each flight, or b) connect a main- tenance charger when aircraft is to be inactive for more than a few days. Some operators have gone with option (a), others with option chemical engineering from the Ohio State University. After college, he spent 10 years at Battelle Memorial Institute working on advanced battery systems for military aircraft. From there, he went to work at Douglas Battery where he developed a full product line of valve-regulated lead- acid batteries for motive power and stationary applications.
