Hi,
I have a question re aircraft tracking and my query is not related to the recent MH370 incident.
Apologies if this is the wrong place - I am new here.
I am not a pilot, although I am currently taking training hence the query.
I am a boat skipper and hold a Commercial Certification, and Instructor ratings.
Perhaps one day I might gain a CPL and FI rating, but I'm in no rush and just want to enjoy real flying.
On ships and boats we have a technology called AIS Automatic Identification System.
It is linked to our GPS and instruments and broadcasts the data in near real-time to other AIS-equipped vessels, and to shorebased stations.
All other vessels within range can receive the data, as well as (CG) Coastguard and VTS (Vessel Traffic Service) for safety and traffic routing.
There are apps and websites that also show the data in near real time for free.
The data includes GPS position, speed, heading, VHF Callsign and MMSI (like a digital telno for boats), as well as other info such as declared destination, Flag State of the vessel etc.
It is a requirement for many Commercial Vessels to have AIS and optional for private vessels, although many do have it.
When on-board, I can see other vessels plotted in real time on my MFD Plotter, with a little data-block next to it with I.D. and speed, and a dotted line showing course/heading extending from the target. The length of the line can indicate its speed and predicted position in 60 seconds (or whatever time period I want).
If the system detects a risk of collision the relevant target(s) will turn red, and a visual and audible collision warning is activated on the display, and the approx. position of the impending collision is marked with a red 'X' on the chartplotter display.
I can then take the appropriate action, or even call the vessel with a few touches of the display to explain our intentions.
Even though speeds are relatively low compared with aviation (my max is 30kts and cruise is 24kts), situations can and do develop very quickly and need quick and accurate resolution in a predictable fashion according to the IRPCS ColRegs so it is an invaluable safety tool (with limitations granted) but is an excellent aid to situational awareness and pilotage planning. Mk.1 eyeball still takes precedence however, with AIS (and radar) a good backup.
My question then, is does such a technology exist in aviation?
After I started flying in my training PA28, I realised that there are differences in tech between maritime and aviation - perhaps because of weight or other considerations BUT, I have to confess that I remain surprised that in such a safety-focussed industry that such technology isn't available - nae - mandatory for all manned aircraft - from micro light to airliner.
The ability to 'see' all other aircraft and their position, horizontal and vertical speed, heading and altitude/height relative to you on an easy to read graphical display must surely be something that has been thought of, and a fantastic safety aid, particularly in crowded skies or during landing/takeoff.
The tech is relatively simple technologically and not vastly expensive.
I am aware, of course, of the function of a/c transponders, but have never seen or heard of anything like AIS in the aviation world.
I have also seen the NATS 'Aware' colour GPS system as a small self contained device that warns about airspace - but not other traffic.
I can only imagine that safety would be greatly enhanced if all aircraft were required to use and maintain such a system.
I am a 'newbie' and realise I'm a bit green in aviation matters, so I wondered if anyone could correct me on the existence or feasibility of such a system?
Regards
