AVIONICS BUS TIE SWITCH
The AVIONICS BUS TIE switch is a two-position guarded toggle-type
switch located on the left sidewall switch and circuit breaker panel. The
switch connects the AVN BUS 1 and AVN BUS 2 together in the event
of failure of either bus feeder circuit. Because power for each avionics
bus is supplied from a separate current limiter on the power distribution
bus, failure of a current limiter can cause failure of the affected bus.
Placing the AVIONICS BUS TIE switch to the ON position will restore
power to the failed bus. Operation without both bus feeder circuits may
require an avionics load reduction, depending on equipment installed.
