Aviation Maintenance Magazine – The Power Behind the Plane: Keeping APUs Running
One of the major operational disruptions for any airline is unscheduled maintenance. When a system like the auxiliary power unit (APU) is involved, the impact can extend beyond a maintenance task to affect aircraft availability and operations. Though the APU is mostly used for ground operations, it is needed to keep both the electrical and pneumatic systems functional during an in-flight emergency, like the loss of engine power. Being a critical system, its continued serviceability is also a key factor in maintaining safe flight operations. Its availability during maintenance operations can also reduce turnaround time for operators.
Hence, airlines aim to maintain APU reliability to maximize on-wing time and reduce aircraft downtime. Even though this seems like a maintenance issue, the challenge goes far beyond just keeping the APU serviceable for operators…READ MORE ONLINE
