I am about to reply to another thread here about the 757 navdata. I would like to comfirm that I have taken the liberty to contact planepath.com  I have gotten a positive yes that Captain Sim is to be added to there list of add-on Airacs as soon as he can get all of the data. He is well aware of this, and is working on it. Please keep an eye out on planepath.com for the release. I will too. I have also contacted Navigraph as well. Still waiting on a reply, but I do have a ticket number incase I don't here from theme.
