Abstract :
M. F. Gunderson (nonmember; Los Angeles, Calif.): The author states that it should be “definitely determined whether radio shielding is necessary.” In view of the incorporation of open-wire circuits in aircraft, it does not appear that battery shielding needs to be considered in future battery design — at least not in all types. Installations in many aircraft of recent design do not use the shielded junction box on the battery. However, present battery A N specifications call for battery shielding.
