load for approximately 27 minutes. If one or both
batteries are weak (low voltage), less on-line time will
be available. Also, the specific electrical load drained
by the Essential Services Bus will proportionally affect
the total time battery power is available. Pilots should
not rely on always having a full 27 minutes (or 12
minutes with just one battery) of battery power available
