#1592 — Malaysia Airlines 777 engines pinged satellites after loss of radar

It appears the engines on board the MH377 flight were equipped with 
Rolls Royce Engine Health Management

"A critical aspect of the EHM system is the transfer of data from 
aircraft to ground. Aircraft Communications Addressing and Reporting 
System (ACARS) digital data-link systems are used as the primary method 
of communication. This transmits the Aircraft Condition Monitoring 
System (ACMS ) reports via a VHF radio or satellite link whilst the 
aircraft is in-flight."

"http://www.rolls-royce.com/about/technology/systems_tech/monitoring_systems.jsp"

"Communications satellites picked up faint electronic pulses from 
Malaysia Airlines flight MH370 after it went missing on Saturday, but 
the signals gave no indication about where the stray jet was heading nor 
its technical condition, a source close to the investigation said on 
Thursday.

The 'pings' equated to an indication that the aircraft's maintenance 
troubleshooting systems were ready to communicate with satellites if 
needed, but no links were opened because Malaysia Airlines and others 
had not subscribed to the full troubleshooting service, the source said."

But now apparently they didn't

This case is so interesting.  My money is still on hijacking, at the
moment.  What's interesting to me isn't the whole terrorism angle but
how many weaknesses it has exposed in systems that are supposed to be
reliable - conflicting reports from military and observers, missing
data, bad records, etc.  "How can this happen in 2014" says the article
I posted over at m.n.i.d.  Go live in a place like Malaysia or Senegal
and get to know how they do business and you find this is no surprise at
all.

I used to live in Indonesia in the early 90s, and once caught a ride on
a copra freighter traveling between the islands.  "These guys must be
awesome mariners," I thought, so I was excited for a look around the
cockpit when invited.  To my astonishment, they were navigating with
nothing better than a pack of cigarettes, a ballpoint pen, and a
photocopy of a chart made by the Dutch prior to WWI.  No radar, no
lights (hardly), no sextant, no leadline, just a pack of smokes and a
whole lot of Inshallah.  

You've got a whole bunch of officials supposed to be on the ball over
there, that probably aren't on the ball at all.

Another dumb then that ICAO did was not put ACARS transmissions on
multi-band HF. A 100 Channels would handle all the airplanes in the world
and we would always know where they were at. They also should have not
allowed the pilots access to turn ACARS off. It should run as long as the
engines are on.

But it would appear that although the engines have this management
system, and indeed communicated with the satellites every so often, all
the satellites did was to say OK thanks (and not ask for engine data)
because the Malaysians had not purchased (i.e. were not subscribed to)
that maintenance option.
