PRES/OXY
A BIU reset should only be performed if the potential
loss of a currently operational system or function is
acceptable in order to recover a failed system (such ENG/PROP
as TCAS or the GEN FAIL ACAWS). Aircraft systems
which interface with a failed BIU may remain in their
last state if the BIU lost 1553 bus communication but FUEL
is still powered. Therefore, resetting a failed BIU could
cause some systems which are still operating (such as
the radar) to subsequently fail if the BIU failure is due to AAR
a non-recoverable fault.
SPEC NOT FOR FLIGHT ELEC

NOTE

Before attempting a BIU reset, the crew should evaluate HYD
the status of the various systems and functions listed in
the Potential Mission Impacts as well as the Fault Log.
