Airservices are making a number of claims in relation to ADS-B for general aviation aircraft. Originally it was understood that an ADS-B ‘out’ transponder would cost about $8,000 and still need to be connected to a separate GPS receiver. The latest cost that is being estimated is about $12,000.
It should me made clear that there is actually no such unit available. Microair have been working on a prototype, however they only have a mock-up. They would need an order or considerable funding from the Government to be able to design and certify their unit. Until it is actually certified, there is no 100% guarantee that such a unit can be manufactured.
In relation to ADS-B ‘in’, Airservices have demonstrated the CDTI-2000 unit from Europe. Of course they haven’t mentioned a price. The prices are staggering. The unit would cost $16,147 plus freight (let’s say $500). An estimate of the installation certification is about $3,000, and it then has to be connected to a GPS receiver and a Mode S receiver. So you are talking about well over $20,000 just to get ADS-B 'in’. That is, a unit that will display the 'paints' of other aircraft on a screen in your aircraft - and this gives no audio call outs at all. Add this to the ADS-B ‘out’ and you are talking about a figure of approximately $30,000 for a GA aircraft.
When you consider that you can buy a really good IFR certified TCAS with voice readout for under $10,000 it seems strange that they would be pushing ADS-B.
