Robert Randazzo has announced on the AVSIM Forums that the 747 V3 has moved into its first stage of testing for FSX and FSX:SE. He went on to explain, that this testing phase involves a Technical Advisory Team made up of industry experts.
This team will provide valuable information to The 747 V3 Team. They will use this information to make the next project build. The second phase will involve a PMDG selected group of simmers. These simmers will work to ensure the product is bug free and ready for release.
As usual, there is no set timeline for these two phases of testing. We will be watching The AVSIM Forums and keep you updated!
