APU shutdown during turnaround
Hi guys
The airline where I work has per SOP to turn off the APU during turn around.
One question... What`s worst for the APU. Lots of hours or cycles? Or is APU like the engines nowadays... On wing until they have problems...?
Now, disregarding the environmental reasons and regs for some airports... if you had none of these... Is this really a good procedure? What are your toughts?
