ASRI and the AFC Requirements and Capabilities

Ladies and Gentlemen:

Greetings! I have been referred to you and your organizations by the National Business Aviation Association (NBAA)

I represent the Aeronautical Frequency Committee (AFC) and Aviation Spectrum Resources, Inc (ASRI).

The AFC is made up of representatives from the Major Airlines, NBAA, AOPA, NATA, HAI and the HSAC with observers from the FAA, IATA and Boeing. The AFC establishes the policies for the use and management of the Aeronautical Enroute Radio Spectrum in the US. The AFC also monitors and provides inputs into international forums (ICAO & ITU) that deal with aviation radio spectrum issues..

ASRI (Formerly Aeronautical Radio, Inc (ARINC) manages the VHF and HF Aeronautical Enroute radio spectrum for the aviation industry in the US and it's territories. ASRI license all the Aeronautical Enroute stations, both voice and data link, used by the airlines, FBOs, flight schools, corporate operators, and other aviation business entities.

Additional information on the AFC and ASRI can be found at our website at

Recently, ASRI customers and AFC members have encountered burdensome and often unnecessary requirements being imposed on them by airports and airport managements when attempting to have radio stations approved for installation on airports or in airport facilities. The committee strongly believes that these problems are largely the result of the airports and their managements being unfamiliar with ASRI, the purpose of the Aeronautical Enroute Spectrum, and the federal requirements for these radio stations. The Aeronautical Enroute Spectrum is governed by FCC regulations and Aeronautical Operational Control( AOC) communications facilities are required by FAA regulations for commercial aircraft operators. The Aeronautical Enroute spectrum and the Aeronautical Operational Control communications facilities provide a safety of life service that is used for both safety and regularity of flight. The AFC membership understands that the airports have concerns that these stations could produce interference with airport and FAA communication systems and in some cases the installations may not meet esthetic requirements of new terminals.

In order to address some of these concerns, the AFC has directed ASRI to provide the VHF Ground Station Installation Guidelines documents for dissemination to airports and airport managers, as well as ASRI customers, to help educate them on the requirements for proper station installation and operation. These Guidelines also address the requirements that must be considered in order to install these stations so they will not interfere with each other or with other communications and electronic systems on or near the airport. These documents can also be reviewed and downloaded from our website (

The primary reason for my letter/e-mail is to request your assistance in getting the word out to airports and airport managements that these documents are available and that ASRI is ready and willing to provide assistance to airports with any questions or problems they might have concerning the installation, licensing, use, or the prevention or elimination of interference problems involved with ASRI ground stations. Any assistance you can provide in this endeavor would be greatly appreciated. You may contact us directly at 410-266-4800 or v Thank you in advance for any assistnce you can provide and best regards,
