Flight tracking- Ikke noe om ELT - Er ikke sofistikert nok

Passenger planes to report position every 15 minutes under new UN tracking plan
 
The United Nations aviation agency will propose a new standard that requires commercial aircraft to report their position every 15 minutes as part of a global tracking initiative in the aftermath of the disappearance of a Malaysian jetliner. 

 The loss of Malaysia Airlines Flight MH370 last March sparked a global drive for a system that would make it possible to pinpoint the exact route and last location of an aircraft. 

 An International Civil Aviation Organization (ICAO) spokesman said on Tuesday that the standard, if adopted, could go into effect in the near term because it would not require new technology on planes. 

 ICAO members are set to discuss the proposal at a major safety conference in Montreal next month. 

 Airline industry group International Air Transport Association (IATA) promised to lead an industry task force last year on the issue and to voluntarily improve tracking while ICAO developed its standard. 

 In December, that industry task force recommended that airlines start tracking planes in at least 15 minute intervals within 12 months, but IATA itself balked, saying the deadline was not practical. 

 ICAO spokesman Anthony Philbin called the ICAO scheme a "foundational flight tracking standard." The agency is developing more stringent tracking recommendations. 

 Advertisement "If (member states) agree to the standard, the safety conference will also be asked how quickly it expects it to be implemented and if it would want ICAO to expedite that process," Philbin told Reuters via email. "Once our states have made their views known in that regard, we'll have a better idea of the time frame." 

 ICAO could effectively force airlines to act because the standards it sets typically become regulatory requirements in its 191 member states. But the agency prefers to make decisions by consensus, making February's conference crucial. 

 Many airlines already track their planes using satellite systems. An ICAO working paper recently noted that the majority of long-haul aircraft already have systems on board that can transmit their position. 

 But it noted that the equipment is not always turned on and that in some locations, including along polar routes, there are gaps in satellite coverage. 

 Asked if radio could be used to meet the draft standard, ICAO's Philbin said voice communication could serve as a fallback for planes that do not have newer technology.


First Air the only airline in the world with black box data streaming
Technology that could have solved the mystery of the disappearance of Malaysia Airlines Flight MH370 is currently used by only one airline in the world: First Air, which flies in the Canadian Arctic. 

 The system, made by Calgary tech company FLYHT Aerospace Solutions, has been around for about five years.

"First Air was the first to say, 'We want the whole deal because our crews and our passengers fly in a very difficult part of the world,'" says Matt Bradley, president of FLYHT Aerospace Solutions.

The system has two parts. 
- The Automated Flight Information Reporting System, or AFIRS, is a blue box about the size of a briefcase that's located in the electrical system of an aircraft. The box monitors flight paths, fuel and engine levels. 

- The FLYHTStream, which streams data from an aircraft to the ground in real time. The data streaming is automatically triggered when the AFIRS detects a predefined abnormal event, and can also be turned on by the flight crew or by ground personnel. 

 More than 400 airplanes from 40 different airlines use the reporting system to monitor fuel and engine levels. But only First Air uses the system in tandem with the streaming system. 

'Not a revenue driver' 
 The airline has had the reporting system in its planes for three years, and it brought in the data-streaming system in May 2014.

"It's not a revenue driver," says Bradley. "It doesn't make the airline money like a business class seat or an extra baggage fee. It costs money." 

 First Air spent about $1.8 million to install AFIRS in its 18 aircraft, and the data-streaming system costs it an additional $22,000 a year.

 Installing AFIRS on an aircraft costs $120,000. The data-streaming system costs an additional $100 per month per plane. 

 "In aviation terms, it's really not that expensive," says Vic Charlebois, First Air's vice-president of flight operations.

For an airline that connects most of the communities in Nunavut, from Resolute Bay in Nunavut's High Arctic to Cambridge Bay on the western edge of the Northwest Passage, it's essential. 

 "Up in the High Arctic, there is no radar," Charlebois. "It is very difficult to communicate with aircraft. To add to the safety monitoring of the aircraft, to have the black box data streamed to the ground and have an accurate position should something happen to our aircraft was just the natural evolution and growth of the product and what we wanted out of it." 

Black box use limited 
 Commercial flights have black boxes that record all flight data and communication, but that information can only be accessed after the box is recovered.

Most planes now have technology that sends out their location. However, some technology only works with radar, and radar coverage is sparse in remote areas, like in the Canadian Arctic or over oceans. 

Other systems aren't able to pinpoint exactly where an aircraft might have gone down, instead giving a search area thousands of kilometres wide.

The recent crash of AirAsia Flight QZ8501 and last year's disappearance of of Malaysia Airlines Flight MH370 have highlighted some of these issues. 

 "I think the general public feels that when they get on an aircraft, they're tracked, everybody knows where they are at all times and that we have the same kind of systems on an aircraft that we expect from our cell phone connectivity," Bradley says. 

 "As we realize from these incidents, that's just not true." 

Industry must act 
 Both Bradley and Charlebois say the aviation industry moves slowly when it comes to new technology. New systems have to be vigorously vetted and sometimes airlines have to wait years before each company's engineers approve the installation of new technology. 

 But Canadian aviation analyst Robert Kokonis says that has to change. 

 "The industry really needs to get their act together here," he says. 

 "With the FLYHT streaming, in the case of the Malaysia aircraft, it would have automatically started to stream the black box data. We would have known what happened to the aircraft and where it actually went down." 

 Bradley says FLYHT Aerospace Solutions has received a number of inquiries about the streaming technology since the AirAsia plane crash last month.
