Hi All,
Please just be aware that iFMS is a very different product from Virtual CDU or the hardware FMC products in the links above.
Products like Virtual CDU provide you with a "portal" on your mobile device to program the FMC built into PMDG NGX or IFLY 737.
iFMS does not do this, iFMS is a nearly fully functional FMC and ND system with LNAV/VNAV functionality on its own, but when programming a route in iFMS for example it will not be copied into the FMC in PMDG NGX.
When flying aircraft like PMDG NGX or IFLY 737, even though you can use iFMS, it is probably better to just stick to the FMC system provided with the aircraft, as it was built specifically for those aircraft, and potentially program the FMC through Virtual CDU if that's what you want to do.
Where iFMS does become very useful however is flying it in combination with standard or add-on aircraft that don't have any (realistic) FMC/ND of their own in which case iFMS is capable of providing you with a very functional one along with LNAV/VNAV functionality which will control your aircraft to fly the programmed route.
There has been some confusion about this so I just wanted to make this clear.
If you have any further questions about this don't hesitate to contact me through the iFMS website.
