No mater how many times you explain it, you still are not getting the point.

My original 'point' was that I could not understand how a pilot could
not know the AP was disconnected based on what is fitted to the
majority of current aircraft.
Now I know that this particular Russian Airbus did NOT have an alarm
but that does NOT give you the right to argue other aircraft also have
NO system of alarm just because ***I*** said it.

I dont have to be a commercial pilot to be aware of this the same as I
don't have to be Neil Armstrong and step onto the surface of the moon
to 'know' it's not made out of cheese. Awareness and knowledge (to a
some degree) can be acquired solely from the written word, videos and
from real pilots of the particular aircraft you are studying otherwise
why have flight manuals, why have detailed manuals about a particular
aircraft when according to you the ONLY accurate and entirely
formidible 'training' MUST be done on a real flightdeck. There is a
cross over of this type of learning for real pilots amongst ANY other
profession - Theory/Practicle
