I was wondering why my brand new A321 has such a low condition? Maintenance Ratio is 118,6% but condition keeps dropping, now it is only 49% whilst my other planes are 98-100% shape. My maintenance provider is Helvetic and game world Croydon. A bug perhaps?
Well, I have my plane on the ground for 5h 10min every night and in addition on wednesdays the plane stays on the ground for 16 hours in a row so I'm providing enough maintenance time all right. Every day (excluding wednesdays) the plane has 5 round trips.
Fixed it by scheduling a flight to another plane. Seems that if maintenance ratio is somewhere near 100% (I had 118%) and when more planes are added to a fleet the maintenance starts to choke a bit. But it's ok now.
if you had a ratio that was displayed in green, you were fine either way with the distribution described above.
bear in mind, that maintance is calculated once an a/c takes off. so if you had a 18 hour work day, the condition might be down to 49%. once it takes off after that 5 hours maintenance break, it should be near to 100% (if not too old)
