Older A 320 maintenance down time

[Magnetic Iron]

Hello,

A question for maintenance professionals, re Airbus 320

Does anyone know the recommended average time for maintenance including non scheduled by Airbus ?

As older Airbus 320 need more down time for maintenance, I would like to know the ratio of amount of hours flown, to hours required for a decent maintenance standard on ground ?

If one´s company has a older Aribus fleet then how many aircraft should one have for backup ? on average,

Thanks in advance

If you have an A320, older or newer, and IF you have an AOC, then you have access to the MPD. Just follow it.
