  Iridian/Roadshow comes to Life  
The Iridian/Roadshow concept was originally presented to Iridium in 1999 - before they went bankrupt. The reconstituted and revitalized IRIDIUM seized upon the concept and developed it... and ran with it. The Iridium satellite constellations have now been exploited by numerous firms with permutations of the original concept of inflight data-streaming to ground-stations. However, because back-to-base data-streams remain an unnecessary expense, they are still not in wide use amongst the airlines. The use of Low Earth Orbiting satellite continuous re-transmission of inflight data from airborne aircraft remains a niche application, mainly utilized for specialist military (unmanned flight) and geologic survey purposes. There are a few safety-related systems in general use (i.e. VIP jets but not in long-haul airlines).

Thus we have a situation such as Jun 2009's Air France 447 where many months, if not years will elapse before that victims' families and airworthiness authorities may conclude a "probable" cause..... assuming that the A330's flight recorders are found and recovered - and contain intact data.

Smile, You're on the New Black Box

Big Brother or "guardian angel"? We'll let the ethicists decide that one as an Albuquerque company releases its latest cockpit security device. Management Sciences Inc.(MSI) has developed a flight data and cockpit voice recorder that not only adds video, it can broadcast the goings-on aboard an aircraft in real time to a ground station. "We're looking for things that tell you what's happening before it happens," MSI VP Kenneth G. Blemel told the Albuquerque Journal. "Its purpose is to be a guardian angel." The company had already been looking at an improved black box for airliners when it landed a $1.5 million contract to build the Digital Download Flight Information Recorder for the Navy, which has since ordered hundreds for use in F-18s. Blemel said the problem with existing black boxes is they only give up their information after a tragedy. With the real-time monitoring abilities of the MSI device, he said ground-based personnel could see a situation unfolding and perhaps take action to deal with it. The box can also make periodic checks of aircraft systems. Besides aircraft, Blemel said the boxes could be used in police cars, fire trucks and other emergency vehicles or even in the home to keep tabs on vital systems.

'Black box' obsolete

 June 12, 2009

 PARIS - WHETHER or not the black boxes from Air France flight 447 are

 found,  the crash has shown that new technology is needed to record a flight's

 last  moments in real-time, an aviation expert argues.

 

 Former Air Canada chief executive and ex-head of the International Air

 Transport Association, Pierre Jeanniot helped pioneer flight data

 recorders  40 years ago but now says the 'black boxes' are obsolete.

 

 'Technology has evolved,' Mr Jeanniot told AFP. 'Real-time data

 transmission from the cockpit by satellite is a lot less costly than it was ten years

 ago. It is now possible to transmit everything directly during the flight

 if there is a problem.'

 

 Mr Jeanniot said an automatic system for data transmission of flight

 information by satellite exists and should now become the norm in the

 industry. It would put an end to painstaking searches like the one taking

 place off the coast of Brazil for AF 447's flight recorders, and allow

 investigators to reconstruct events in only a few clicks of a mouse.

 

 'The plane would begin to transmit data only from the time that a

 malfunction occurs,' said Mr Jeanniot. 'The system can be programmed so that in the

 event of a serious malfunction, it transmits all data and cockpit

 communications non-stop. It's quite simple.'

 

 The new advanced technology would eliminate the need for costly and often

 futile searches for black boxes at the bottom of the ocean or deep in the

 jungle, using helicopters, submarines and mobilising rescue teams.

 

 'Through satellite transmission, everything can be collected instantly. We

 can know exactly where the aircraft has dropped,' Mr Jeanniot said.

 

 More importantly, the valuable data would help grieving families. 'Can you

 imagine how hard it is for families to be left not knowing what happened

 for  months, sometimes years?' he said.

 

 A small Toronto-based firm StarNav is developing the state-of-the-art

 system  to provide the real-time connection between the aircraft and the ground,

 said Jeanniot.

 

 As the data would only be monitored in the event of a problem, most of the

 flights would not be transmitting anything at all, and there would be no

 risk of overloading the satellite linkups, said Mr Jeanniot. -- AFP

PARIS AIR SHOW: Streaming flight data back to base 'is possible and affordable'

Since Air France 447 went missing over the Atlantic on 1 June, the subject of why detailed flight data is not streamed to base in real time has been resurrected.

Calgary, Canada-based AeroMechanical Services (hall 3, F49) says data-streaming is possible and affordable right now.

The argument for data-streaming is that, if comprehensive data of the type available from a digital flight data recorder were available in real time, the causes of the loss of an aircraft would be available much sooner. Also the results of failure to recover a recorder, or to retrieve the information from it, would be alleviated.

When the Air France Airbus A330 went missing with all 228 people on board, one of the unusual aspects of the early statements by the air accident investigator, France's BEA, was that it was able to quote some technical data from the aircraft, sent just before the accident.

It had been linked to the airline's engineering base by the aircraft's airborne communicating, reporting and addressing system. But the chief investigator Paul-Louis Arslanian has since made clear that although the ACARS data would prove useful in the investigation when more is known, it did not provide any causes, merely a few symptoms.

AMS, however, supplies what it calls an automated flight information reporting system, and provides a total service to users by receiving the data and instantly passing to the operator data that contains exceedences in any category the customer specifies.

The data, processed by a "smart box" developed by AMS, is transmitted via the Iridium satellite network to a ground station and then via the internet. It is sent in compressed batches every 5min, but it contains all the data since the last batch and can be streamed like information from a flight data recorder. If the system recognised exceedences, real-time streaming is triggered. AMS markets the service under the name of FLYHT.

If the pilots see systems information of any kind that they wish to notify to base, they just push a button and the AFIRS streams the data immediately. It also provides them with a two-way voice link. AMS president Richard Hayden says compressing the data keeps the service affordable, and transmitting it via Iridium means there are no global transmission black holes.
