The price of a lie: The cost of ADS-B in Alaska

When will the price for Capstone ADS-B equipment see a reduction now that the FAA has announced that ADS-B out is to be used in the national air space for NexGen?

Experts and FAA officials say that manufacturers will not build any Capstone style ADS-B in and out (978Mghz) equipment until there is a standard. Once a standard is in place production will proceed and prices for the equipment will drop. Provided the FAA approves the Capstone style ADS-B nationwide.

According to a response to the Notice of Proposed Rule Making for Automatic Dependent Surveillance—Broadcast (ADS-B) out performance requirements to Support air traffic control service 72 Fed. Register 56947 (proposed October, 5, 2007) Docket No. FAA-2007-29305 by the Air Transport Association, the FAA has yet to set a standard for ADS-B out and in. The ATA recommends using both (Capstone like) in the NAS, not solely ADS-B 1090 Extended Squitter out.

The Air Transport Association is made up of major airline members, and represents their interests. In their response to the NPRM the ATA voices their concern about this issue as one of the main stumbling blocks of ADS-B equipage issue, and implementation into the NAS.

“…the ATA is concerned that FAA already has signed a contract to initiate the implementation of an ADS-B ground infrastructure, but has not developed operating applications or technical standards for ADS-B In, nor reasonably assessed the substantially greater potential impact on operators of ADS-B In.

In other words the Capstone ADS-B used here in Alaska has “Out” and “In” and the FAA has yet to set a standard for both being used together.

The ADS-B out signal on 1090Mghz has an International standard adopted by the U.S. that is shared for ADS-B, TIS-B and air traffic control.


The “ Capstone ADS-B signal standards on 978 Mghz” issue is of concern here in Alaska now because Gov. Palin recently signed into law a low-interest revolving loan to equip Alaska aircraft with ADS-B.

The question here that is dying to be asked is…how could the FAA ask the State of Alaska to kick in money to equip aircraft if there is no “standard” for the equipment to be compatible, in the future?

Hank Krawkowski, chief operating officer for the Air Traffic Organization, said the FAA needs the Capstone Statewide Agreement Implementation Committee to obtain the funds under a memorandum of agreement for the state to receive $187 million in services from the FAA. This figure is included in proposed budgeting for Alaska of $493 million for future aviation infrastructure improvements.

I’ll bet Sarah Palin did not know that when she penned the bill to create the loan, another interesting detail is whether the Alaska Implementation Committee who signed an agreement with the FAA is aware of the limitations in front of them?
