Most common reason:
Once the MCD opens, there’s a 8? minute timer that begins. That gives you time to update landings, takeoff power, Cat 3 or RNAV logs. When the timer ends, the data is sent. (You can tell when this happens by the ACARS landing data going all blanks) If you power the aircraft down early or pull the red CBs for the FMS/ACARS before the data is auto sent, it will usually trigger the ACARS time emails as it didn’t receive the data and had to rely on early times sent pre- block in. (Your fleet may vary)
