I think something might be wrong with the aircraft condition levels... I have MD80s that average around 12 years old, and the condition level dropped really fast on them and caused huge delays. When I had 2, one was at 71% and one at somewhere around 60%. I checked a little bit later last night, and the 71% had improved to 82% and I fixed the 60% to 71%. Now, the 71% is down to 67% (overnight), and the 82% fell to 75% (overnight). Not to mention I got a new MD80 that quickly fell to below 70%. Am I going to have to repair these aircraft every day???
