Mid-continent Instruments (www.mcico.com), based in Wichita, has been marketing its 4300 series electric attitude indicator since the middle of last year. What makes the instrument notable is its lead-acid cell array battery backup, which provides up to 60 minutes of operating time in the event of an electrical failure in the aircraft.
