Not necessarily. As I mentioned earlier, if you ask it to do something for which it doesn't have data, it'll go to IAN to make up its own. The 400 didn't have this mode, so it would just arm the mode and wait until the data became available. In this case, you're doing the same thing before the data is available, and the 748 is just assuming you want to just run with whatever it can give you.

Ok that makes sense, ill definitely make sure i get both deviation indicators & its stable before i select APP. Ill report back on the results. Thanks again for your help my friend!

If the aircraft is not receiving a GS signal then it pretty much has to default to GP.  Right?  The FSX/ESP/P3D platform has a very rudimentary simulation of an ILS and when we add IAN to the equation then the simple simulation model reveals its weaknesses.  For purposes of simulation, I recommend waiting until you show indications of receiving the signals before arming APP.  Note that the simulation has a much shorter range for GS than for the LOC, and neither are representative of the real world.

Yes sir that makes sense. I will definitely wait till both are active before arming & see what happens. Thanks for your help my friend!

Gents, I just completed a test flight, I waited until both LAT & VERT deviation indicators were established with the ILS. Worked perfectly!  Issue solved. Thanks again guys.

Welcome. Glad to hear it.
