Dear all,
we have inducted some new b777 300ER's
the above is a snapshot of the MANAGER MESSAGES of old a/c compared to new a/c
FYI we don't have HFDL & SATCOM LOW GAIN in old or new b777.
We have the rest of the stuff.
my question is In the new a/c which has more messages as you can see, the ones highlighted in red about ATN, why is there a separate message on ATN for both VHF & ACARS section? Is it because of the difference in the AIMS BP software installed (all are BP V 17.X)
or is there an extra feature that exists in the new a/c which old ones DOESNT have and what is that ?
'NO ATN LINK' VHF msg can be expected to be seen in which airspace and what failure exactly?
I am am well aware of the VDL m2's & GOLD & other jazz. But this new inclusion is creating doubts.
Kindly pardon my ignorance if I have overlooked something.
THANKYOU & regards
