Start Preamble


Federal Aviation Administration (FAA), DOT.


Notice of proposed policy.


The FAA is proposing to reduce the number of radio frequencies used by flight service stations to communicate with aircraft in flight. Under the proposal, six hundred and sixty-six (666) remote communications outlets (RCOs) will be decommissioned. Frequencies especially designated for emergency or military use are not included in this proposal. Frequencies in the state of Alaska are also not included in this proposal.

The Federal Aviation Administration maintains a network of over 2,100 remote communications outlets (RCOs) throughout the conterminous United States, Hawaii and Puerto Rico. The RCOs are used by its contract service provider, Lockheed Martin Flight Services (LMFS), to communicate with pilots in flight. Pilots can obtain weather briefings, file flight plans and receive numerous other services by using these frequencies.

The frequency infrastructure currently in use was developed nearly 50 years ago, with little or no modifications since. In 2005, LMFS took over flight service operations at 58 locations in the Conterminous United States (CONUS), Puerto Rico, and Hawaii. In doing so, it inherited a vast network of 2,162 frequencies used to provide a variety of services. For example, 347 frequencies are designated for emergency use only and 194 frequencies are designated for military use only. These 541 frequencies are not being considered for removal. The remaining 1,621 frequencies can be divided into two groups.

(1) Remote communications outlets in which aircraft can contact a flight service station by transmitting and receiving on a common or discrete frequency, for example, 122.2, 122.5, etc. There are 1,223 RCOs in the CONUS.

(2) Frequencies that are co-located with navigational aids known as VORs in which aircraft can contact flight service by transmitting on a frequency (usually 122.1) and receiving on the appropriate VOR frequency. There are 398 VOR frequencies in the CONUS.

The 1,621 frequencies cover a vast majority of the conterminous United States and include duplicate, overlapping and seldom used frequencies. Last year, FAA contracted the MITRE Corporation to study the areas covered by RCO and VOR frequencies for possible removal without significantly impacting the area of coverage. The study concluded that as many as 666 frequencies could be removed and still provide 99-100% coverage at 5,000 feet; 98-100% coverage at 3,000 feet; and 93-100% coverage at 1,000 feet.

The FAA proposes to begin decommissioning 666 remote communications outlets in the Conterminous United States, Puerto Rico, and Hawaii in late 2017. Several types of frequencies are not considered a part of this proposal: Frequencies especially designated for emergency or military use; frequencies in the state of Alaska; and Ground Communications Outlets (frequencies used by pilots while still on the ground).

By reducing radio coverage, the Agency estimates that it can save approximately $2.5 million annually in maintenance costs alone. Additionally, more savings will be realized once property leases are terminated and voice-switch communications infrastructure is decreased.

By soliciting comment to this notice, the FAA seeks to address public concerns and will consider any comments in determining whether to change the policy.
