While the plane itself may have a minimum of 2 ELT, they were also rated for oceanic flight and must have emergency rafts.....I was under the impression these days they have ELT too. Isn't the lack of communications and evidence way odd? The ones in the raft almost certainly wouldn't be impact activated. Would they be EPIRBs? |

They are all tracking transmitters with perhaps differences in how they are used/features. Might some individuals also have PLBs? Regardless, it get's weird when there is absolutely no communication reported. Ballista's report that this airline is also one of the very few in an 11,000 airline fleet not to have the free INMARSAT tracking is also quite interesting. |

Seriously though. Isn't a bit pathetic that in today's day and age with all of the satellite and location technology that is available, two airliners full of passengers have simply disappeared into the twilight zone in less than one year?
ETA: my cheap 23' sportfishing boat has an EPIRB on it that activates when the button is pushed or when it is submerged in water. They cost a few hundred dollars. How the hell can two $100MM aircraft full of people vanish with no trace. It tells me that the world aviation community has some catching up to do..... |

Inmarsat to provide free global airline tracking service
In advance of the conference on aircraft tracking being hosted by the International Civil Aviation Organization (ICAO) in Montreal on Monday, 12 May, Inmarsat has confirmed it has proposed to ICAO a free global airline tracking service over the Inmarsat network, as part of the anticipated adoption of further aviation safety service measures by the world’s airlines following the loss of flight MH370. <snip> I believe this is a CYA statement, just released from AirAsia: AirAsia's fleet of short-haul jets have been receiving tracking upgrades, but plane lost en route to Singapore had not yet been modified |

I have not seen any [EPIRB} with round the world coverage. GPS is global. Polar orbiting satellites would cover gaps where geosynchronous satellite coverage is inadequate. Yes, gps is. The issue is the transmitting of the location of the unit. There is still a coverage gap. The one I looked at still said there were still dead zones for the 406mhz. Do you have a website showing the coverage gap? I would be surprised if the 406 MHz systems on geosynchronous satellites is not effectively global (excluding polar regions). I will have to do some research. Low polar orbit (528 miles), each of 5 POES/SARSAT satellites completes an orbit every 100 minutes, angle of orbit is 99 degrees off equator. These use doppler effects to get fixed location of beacon. Geosynchronous Orbit, 10 GEOSAR Satellites Spaced out roughly every 30 degrees of longitude, with some wide variance, these can't use doppler, so rely on multiple satellites to receive to triangulate. Both types of SAR Satellites are additional payloads on other satellites, such as GOES-E for geosync, and METOP-A for one of the polar orbits. NOAA info on Cospas-Sarsat Cospas-Sarsat usage statistics, seem to cover the entire globe From the last link, here are the rescues aided by SARSAT: So, based on your picture, if you're over water and the plane your flying in connects with SARSAT, you better hope you're near land becasue water rescues are still not (likely) gonna happen. |

The sad part is that INMARSAT offers free satellite tracking but this Airbus POS did not have it installed. It's free and they still did not have it. https://pbs.twimg.com/media/B6Dco5dCQAAjSvg.jpg Quote HistoryQuoted:

Most of this was my bitch about the last one when most of the people here assured my how impossible and expensive it would be to do. Wonder how much per day a military ship costs to blindly search the ocean? The sad part is that INMARSAT offers free satellite tracking but this Airbus POS did not have it installed. It's free and they still did not have it. https://pbs.twimg.com/media/B6Dco5dCQAAjSvg.jpg Free or "Free" (with the purchase of a $35,000 piece of equipment that must have new firmware updates installed every 180 days at a low introductory rate of 3 easy payments of $4,999.99 per update). That company is in business for profit... So where is the charge... |

Pentagon: Details of Indonesia's request for US assistance in AirAsia search still being coordinated; could include some air, surface, sub-surface 'detection capabilities' - statement How long was it before the US was in on the MH370 search, dropping sonobuoys all over? I'm also curious as to how many of the search "ships" have the equipment to detect the 38kHz beacon from the CVR/CDR boxes. The picture of the inflatable boat as a search craft did not instill confidence. |
