Trans States Holdings, Inc. Implements AIRS For Flight-Critical Communications

Share Article

AIRS™ provides a growing number of air carriers with increased operational efficiency through reliable data communications services designed to keep flights on time.

AIRS™ allows airlines to take control of their data communications with open, flexible architecture.

Trans States Holdings, Inc. has implemented the AvFinity Integrated Router Solution™ (AIRS™) for flight-critical communications that include filing flight plans, submitting Advance Passenger Information System (APIS) crew manifests, and sending and receiving operational messages to and from airline partners.

Trans States Airlines, GoJet Airlines and Compass Airlines make up Trans States Holdings, Inc. The corporation’s headquarters is at Bridgeton, MO, near the Lambert-St. Louis International Airport.

AIRS™ comprises AvFinity patent-pending software technology embedded on a Cisco Integrated Services Router. AIRS™ is a plug-and-play appliance that provides data management, routes and formats messages, enables connectivity to government border and flight authorities and much more.

AIRS™ allows airlines to take control of their data communications with open, flexible architecture that enables messaging transformations, such as reformatting IATA to ICAO flight plans, all through AvFinity’s patent-pending scripting innovation.

Trans States selected AIRS™ to:

  •     Manage APIS crew manifests for its international flights. AIRS™ satisfies APIS requirements through assured delivery of the manifests to U.S. Customs and Border Protection, the Canada Border Services Agency and CARICOM (the Caribbean Community).
  •     Connect Trans States to the U.S. Federal Aviation Administration’s NADIN II for filing flight plans using the most advanced technology.
  •     Enable specific operational messaging to partner airlines without the need for third-party legacy messaging providers.

AvFinity is one of the first aviation companies to facilitate connections to the FAA using modern TCP/IP protocol rather than a legacy dedicated circuit. The new system is based on the FAA’s Common Message Handling Protocol (CMHP).

Using this protocol, AIRS™ redundantly connects to both the FAA’s Atlanta and Salt Lake City centers. Should one of the connectivity points fail, the system switches automatically between the two centers within 3 seconds. That increased reliability built into AIRS™ allows airlines to relieve their costly legacy dedicated X.25 circuits.

Due to the high bandwidth advantages of CMHP, flight plan filings occur in a fraction of a second. In addition, AvFinity now offers additional products from the FAA including NOTAMs.
