Hi. I have been trying to find documentation on how to make the weather radar in the 777-300 work. From what I can find on the internet, it says to read the SP1 Supplement documentation to see how to make it work. The trouble is I can't find the SP1 Supplement anywhere. Not in my PMDG Ops Center or on the internet. So, just wondering if anyone has an idea on where I can find this document. I emailed PMDG a few days ago but not response. I am sure they are very busy.
Thanks in advance for any help pilots.
Have a great day
