Mechanism
Active Redundancy
TL;DR
Aircraft hydraulic systems illustrate active redundancy: all three systems operate continuously, so failure of one leaves two functioning without delay.
Multiple systems operate simultaneously, sharing load. If one fails, others instantly absorb its load without switchover delay.
Business Application of Active Redundancy
Aircraft hydraulic systems illustrate active redundancy: all three systems operate continuously, so failure of one leaves two functioning without delay. Active redundancy provides instant failover but requires continuous operation of all redundant systems, increasing costs.
