I use Project ai for my traffic files and have noticed on several different flights that you will hear ATC tell a flight to climb to flight level whatever and than repeat it about every minute or so. It sounds like for some strange reason that the plane can not make it to the assigned altitude. It is diferent flights but I am not sure if it is different aircraft. I have not started to make a list of the flight number so I can look them up and perhaps edit them. Has any one else noticed this problem.
I some times turn AI off for a minuete or so and then turn it back on to reset every thing. I get tired of ATC constantly telling flight *** to climb to flight level ***.
I know if I can get the flight number of the culprit I can edit the altitude to a flight level that the plane should be able to reach.
I was just curoius ???
