This is comical. Post after post about an ELT mounted in the aircraft and its supposedly hidden activation system is debunked by forum members that are actual crew and maintenance engineers. According to these very experienced personnel, the presence of the ELT in the aircraft is unlikely, and a hidden or disguised activation switch is something that has never been seen or even discussed by those familiar with the aircraft in major airline ops.
Then you reference catalog information on an ELT. The manufacturer, Artex, states:
This statement gives no further information about the interface. How does it interface? Does it provide information to the MCS, does the MCS control the ELT, or both?
The Artex literature further says:
Stating that the Artex ELT is "approved for use" in the B777 does not mean that the Artex ELT is installed in every B777 now flying. But you certainly make that assertion.
You also claim the MCS "can activate the ELT". From that, your next post ups the ante by saying if the aircraft ran out of fuel in flight it would have "triggered the Master Caution system and activated the ELT automatically while in flight".
You again make the unequivocal claim that the "Master Caution System would have activated the ELT before going down".
[B]So from vague catalog phraseology stating the Artex ELT will "interface with Boeing's Master Caution System" you make the rather fantastic leap that the MCS will automatically activate the ELT if the aircraft runs out of fuel.

Based upon posts be those that actually fly and maintain the B777, it appears your contention regarding the presence of the ELT, much less its interface and communication with the MCS, is completely without merit.
