However, Plumbum. The IATA are ALL for it..so go figure.
It really amazes me how the argument changes from 1090ES being horrendously expensive and then suggest an even more expensive UAT or a white elephant VDL4 as a better option...would an AWI cast a more sympathetic eye as to the cost of such ubber-exotic equipment?
Do we really have to go back over the modeAC codes as opposed to the modeS unique identifier in each 1090ES unit...what was it, 24bit..the same number of codes as a three letter, three digit number plate system. Then you should be argueing about fruit , ol' fruit
East Coast US will hit it as well as Europe if there is no rationalisation of the DME frequency band.
Code saturation is a red herring!
UAT is a datalink, 1090ES is a transponder. In the US GA on UAT will also have to carry an operating mode AC transponder not as a back up but to make the
plane visible to the rest of the poor sods flying in the same airspace with TCAS...1090ES does not suffer from that issue.
On top of all this we have little Francois who just doesn't want it..and you guys want him to expend even more money to access airspace?
Now...the cable that connects airservices and the content providor with your UAT system, Plumbum....who pays for that? and...IP or dedicated Airservices secured? Ask Enigma how hard it is to get access to the Airservices TAAATS feed and then ask yourself how big a can of worms you intend to open. The box may be the same but the infrastructure that connects to it is where the real cost is.....1090ES is one way traffic back to TAAATS...UAT requires a dedicated individual SECURE connection for each individual transmitter that transmits ONLY the data that would be in range of the receiver/transmitter....all this on a twice a second update???? why is it that the yanks are happy with the once every 12 or 20 seconds update...bandwidth? or the delay to get the UAT transmissions and combine it with the raw radar/ssr feed and then reroute and transmit....How many TRACONS spread out over the US and how many in Oz? BN and ML? and you want data transmitted along secure cable to each individual transmitter????
Have a think about what you ask for, plumbum?
