Take a look at the approach plate for Juneau—it gives a 2,foot or so MDA with two to three miles of visibility required. This proposal envisioned rapid deployment and field demonstration of advanced avionics capabilities leading toward implementation of free flight. The concept of conducting a real-world demonstration of these and other capabilities in Alaska was originally proposed for inclusion in the FAA’s Flight Program. While three of the accidents involving non-equipped aircraft resulted from poor runway conditions, no Capstone-equipped aircraft were in such accidents. ADS—B aircraft position reports were also made available to airport traffic controllers in Bethel and to the commercial-aircraft operators via the Internet for flight-monitoring purposes.

As an example, the additional aviation weather observing systems the NTSB called for in Alaska relies on the Flight Flight Information System element to provide the information developed via data link to the pilot. The accident, which took place on takeoff in clear weather, was “not a type of accident that Capstone was designed to address. Capstone officials plan to complete the initial low-level IFR route structure in May The concept of conducting a real-world demonstration of these and other capabilities in Alaska was originally proposed for inclusion in the FAA’s Flight Program. The Capstone Program was a United States government-funded aviation safety program for the state of Alaska , primarily focusing on rural areas of the state. Does it represent the FAA at its best? We need to commission WAAS-based approaches and airways.

Installation is extra—every airplane is quite different! Capstone sought to address this by using ADS—B technology to reduce airborne collisions. A key objective of Flight had been to accelerate implementation and use of modern technology; however, uncertainties surrounding that program actually slowed the transition.

Capstone: Heating Up in Alaska – Avionics

Currently, the infrastructure includes a thin scattering of ground-based navaids, largely VORs and NDBs, which require line of sight to successfully transmit signals. More on the study later. The bundle of avionics were installed on aircraft used for commuting, chartering, and mail flights in southwest Alaska.


This section needs to be updated. UAA also provided crew training on the Capstone avionics equipment.

The GPS signal had an availability of about Within the Alaskan Region, Flight served as the “capstone” for oroject additional initiatives, providing a common umbrella for planning, coordination, projet, and direction with regard to development of the future National Airspace System NAS. This land-based system resulted in a traditional IFR route structure that was not optimized for the terrain or typical small aircraft users in Southeast Alaska.

The initial results showed a 40 percent reduction in accidents had resulted from the Capstone Program.

The initial evaluation concentrated on an affordable means to reduce CFIT and provide the pilot with an enhanced means to see capstoe traffic and receive current weather in the cockpit.

Within reason, we believe that the more information we can put in the cockpit, the better! The flight standards folks interpreted the existing rules as requiring equipment to receive ground-based navigation signals for operators flying IFR. Capstone utilized WAAS receivers in all participating aircraft.

The FAA’s Capstone Project

Of the seven Capstone-equipped aircraft that had accidents, “only one was of the type that the new technology should have prevented.

For more on the ISER study, visit www. Researchers caution, however, that it is premature to “assess whether this is a systematic change that will continue, or just the result of chance variation. The Capstone program consisted of two phases in different geographical areas of Alaska. The Minimum En Route Altitude MEA of the airways were typically above the altitudes that the general aviation fleet of aircraft could safely fly without encountering icing conditions, even in the summer.


Not all the challenges for Capstone have been technical. Please help improve this article by adding citations to reliable sources.

For example, one controlled flight into terrain CFIT accident occurs on projevt every nine days in the state. Only one Capstone-equipped aircraft was in a fatal crash. This reduces the decision altitude at Juneau by more than 1, feet,” says Cieplak. Legacy en route navigation aids required land-based sites where power was available and maintenance crews had access.

Archived from the original on December 8, This mode detects faulty GPS satellites and excludes them from the navigational solution.

General aviation in Projec is different. Researchers “looked at the accidents and found that if the new technology had been installed on all aircraft in the test region during the s, it might have…prevented one in seven accidents and nearly 50 percent of the fatal accidents,” according to the study.
