Performance Factor
 

Dear All

Do you know the minimum and maximum level of performance factors of Airbus aircraft. Is there any manual we can check this and in which chapter/page ?

Is there any method that we can calculate a approximate figure (aircraft performance level) considering the flying hours of an aircraft ?

What checks or maintenance (eg: core wash) would be more effective to improve the performance factors of aircraft ?

Appreciate your comments
