New AC delivery: notification when scheduled delivery changes?

[weasel]

I ordered some aircrafts when a new type was announced, planning to replace my current fleet with it and extended lease periods accordingly (while learning that extending a lease by some months makes it much more expensive, but that topic has been discussed before). When checking again after some months (game time) I noticed scheduled delivery has been delayed. While I'm perfectly fine  that delivery of an uncertified A/C might be delayed, shouldn't there be a notification? Is there a notification in general if planned delivery dates change, e.g. early or late?
