New technologies in aviation come about to solve problems and make air travel safer. From this new technology, controllers will have increased situational awareness.
Air traffic control relies on positive and procedural navigation: positive uses radar; procedural uses the radio-procedure of pilots reporting their position every few minutes.
Gander Automated Air Traffic System Plus (GAATS+) is Canada’s new trans-oceanic flight control system developed especially to help deal with sixty percent (the percentage of jets equipped with GPS position-reporting and text-based communications avionics) of the thousand jets crossing the North Atlantic daily (just as Air France 447 did.) It reduces radio procedure by extending positive control via north coast radar feeds.
The new technology is an advance in integration which automates ATC processes (taking advantage of the newest GPS technology, ADS-B and ADS-C) and is expected to save client airlines a million in fuel yearly. It is said that GAATS+ “provides significant enhancements to the original GAATS system, including electronic flight strips and increased automation of data exchange with other ATC facilities. GAATS+ also integrates automated flight plan processing, track generation, advanced conflict prediction and data-link communication for position reports.”
Of course I can not help but have opinions on operational technology, even without a single tangible thing that qualifies me to have an opinion.
The phrase that caught my eye is the statement that “GAATS allows reduced separation by lessening reliance solely on procedural control.”
I am not now nor will I ever be working in a control room. I will have to take the word of Air Traffic Controllers on how this system will work at making flying safer.
My opinion is only based on a layman’s experience and too much attention paid to aviation detail. I only see a few sticking points and they are broad ones:
- The technology conundrum: Technology is good because it brings greater efficiency; but sometimes I wonder if a reliance on technology will allow skills to atrophy. Will a system like this ultimately result in less able controllers, the same way cockpit technology has resulted in less able pilots?
- Separation conundrumI hear the phrase greater separation, and I think, “okay, these planes won’t impact each other; they’re safe from direct contact and wake turbulence.” So when I just see the GAATS literature talking about enabling “reduced separation,” what perceive a greater possibility for direct contact and/or wake turbulence. I know the idea of a 5 minute longitudinal separation as opposed to ten is intended to mean greater capacity for traffic. But increased technological accuracy and precision in tracking jets is a good thing only as long as we don’t use the precision in a way that is ultimately chancy.
- New software conundrum Anyone who has ever had a system knows that the bugs in the system don’t show up right away. They are discovered at various points whenever parameters are stretched or unexpected /unanticipated/ extraordinary events occur. Even when software is not beta any longer, ( las GAATS+ is the latest incarnation of existing GAATS), it is still a developing work in progress, as new problems are revealed and are bridged. So we can only hope that any bugs that exist will not be fatal ones.
