I love the old lady too. You are right, looking from today, the details are not "state of the art", but compared to a lot of other FS products released in the last ten years from other developers, the MD11 is miles ahead. The systems are acruate simulated and you can feel like a real MD11 pilot. Yes, a weather radar and ACARS weather Link would be fantastic. I am sure, PMDG would find many new customers for this bird, if they will add this features. The model is more than ten years old and not so nice, but hey, your place is on the flightdeck! May you pimp the Model up with some HD-repaints.
Cheers
