  1. I agree Andy... in todays technology surely general monitoring is the norm???? Even I read in disbelief that the engine pings are hourly... Is there soooo much data being streamed that the pings have to be 60 mins?? Make it 10min with a lat /long and we would have been looking in the right place two or three weeks ago IMHO.. A lot of manpower in the wrong place as it turns out on several occasions...

    I'm not sure who called them "engine pings". They have nothing to do with the engines. They are part of the satellite terminal functionality. They occur once every 64 minutes.

     

    I think the misunderstanding originated from a person who probably had at least some technical knowledge of the satellite link breefing a journalist who, of course, was technically illiterate and he / she dubbed them "engine pings".

     

     

  2. What's ACI?

     

    Read the report. The crew asserted control over the aircraft and continued to navigate. Only then did they transmit. The is the correct procedure. Subsequently, they requested airspace.

     

    Until the crew can aviate and navigate there is no point in communication with the ground. What are they going to do?

  3. QF2 sent out a PAN call. Passengers have phones, and there's precendent for passenger calls from aircraft in trouble.rgmwa

    Yes, QF2 did send out a PAN - eventually - because it was landing. But they had already brought the plane under control.

     

    The last reported position of the plane was 90nm - approx 170 Km - from the eastern shore of Malaysia. Not good for cell phones. In any case, in the event of some catastrophic it is very rare for passengers to make a call.

  4. I'm inclined to agree although the lack of any distress calls from either of the pilots (or passengers) while the plane was being turned around, despite indications that the comms equipment was still working at the time, is puzzling. Wherever it finished up, I don't think anyone on board was still alive.rgmwa

    Avaiate, navigate, communicate. For instance, Air France 447 sent no distress call. In fact most airline crashes sent no call. Why would they?

     

    The passengers had no comms.

  5. Cut and paste from article.....Authorities have said someone on board the plane first disabled one of its communications systems - the Aircraft and Communications Addressing and Reporting System or ACARS - at 1.07am.

    About 14 minutes later, the transponder, which identifies the plane to commercial radar systems, was also shut down.

     

    The fact they went dark separately is strong evidence the plane's disappearance was deliberate.

    But Malaysian airlines has just negated that article. All that can now be said is that the acars went off between 01:07 and 01:37.

     

     

  6. It now appears that the last acars message was sent at 01:07. The next message was due at 01:37 but was never received. This means that it was possible that the acars and transponder went off at 01:21 and after the last voice communication at 01:19.

     

    This means that some sort of equipment failure is possible.

     

    The information about the acars comes from Malaysian airlines.

  7. Maj,Well the 777 if it had a failure like QF32 & knocked out all the communications landed perfectly in the ocean like the US airways one did in the Hudson river and quietly sank to the bottom leaving no wreckage, so instead of looking for wreckage we should be looking for 240+ pax sitting on the escape slide life rafts.

     

    If she went in hard there would be bit's and pieces floating everywhere and with the amount of countries searching and the resources used I am sure something would have been found by now.

     

    Me thinks something a wee bit more sinister happened and it is in another ocean a long way from where they are looking or it is crashed in a jungle somewhere in remote Vietnam.

     

    I could be wrong, I probably am wrong and I have been wrong before.

     

    Time will tell eventually one hopes especially for the families of the souls onboard.

    The SATCOM was powered up until at least 08:11 Malaysian time(GMT+8).
