With other products now utilising ARINC 424 data - allowing RF legs etc, is this something we will see now for the next PMDG aircraft? This was discussed a couple of years ago,but not heard any updates since.

 

Will the 747 have it? Or will we have to still fudge flying the ever increasing number of approaches/sids/stars that require this capability?

There has been no hint that the PMDG 747 will have any different navdata format than their other products, as much as I hope for it I'm not expecting a change .
