Avionics question about B777 ACARS
 

I've got a general question that an avionics tech should be able to answer re ACARS normal power up and normal shutdowns.

In a typical ACARS unit, fitted to say a B777-200ER, when the unit is powered down by the normal button sequence, does the unit sent a shutdown message to the ground station, or does it simply click off without messaging ?

What do you mean by powered down?
I'm not sure it is.

Powered down as in end of flight at the gate. It would have sent a 'brakes' message however when everything is shut down including electrics, would it sent an automatic "Logging off" or similar message before it shuts down ?

...and your point is???

cant really be answered, as with most things the airline could programme what it wants. why would you have it set to do what you have asked ?
