Tagron, you are not alone, I mean nobody (who blogs could get hold of :o) were able to say what this particular TU154M re-furbished can do and what it can't. Westerners know their side of equipment, Russians know their side of equipment, how those auto-piloting systems from 2 worlds were clipped together, that is, to which effects, practically, in details - is a mystery.
When it beeps, for example, being switched-re-switched mode to mode. To be able to tell from beeps in the record (or their absence) - at least - to get some orientation.
Can an automated go-away be exercised (seems to be prohibited by ordinary TU154) (not M) manual without ILS.
Then - one thing something is prohibited, another thing is when it is doubled "anti-fool-proof" type in equipment. That is, one presses presses buttons - nothing happens. Or does it work anyway, just "not recommended".
