In Focus: Aviation Type B Messaging Uses

After the many technological advances we have seen over the last months and years we wanted to do a focus piece on one of the fundamentals in aviation communications for business aviation and commercial airlines, and how one company has lead the way in providing Type B communications.

AviNet Type B messaging provides reliable and economical messaging for mission-critical business-to-business communications for the aviation industry. Processing over 15 million messages daily to over 700 industry users worldwide, AviNet Type B is used for a variety of message types including GLOBALink ACARS®, passenger reservations, weather data, and flight planning.


ACARS (or Aircraft Communications Addressing and Reporting System) is a type of aircraft communication system which was designed by ARINC to replace the VHF voice service (the voice service was used for all communications between aircraft and ground stations before the introduction of data link). The ACARS system was first introduced in 1978. ACARS is the only data link infrastructure with pole-to-pole global coverage, therefore used to deliver the critical reliability airlines depend on all their flights.

Passenger reservations

Passenger reservation is part of the process of an airline computer reservation system. The system contains airline schedules, fare tariffs, passenger reservations and ticket records. Passenger reservations are offered as part of ARINC’s AviNet Type B messaging.

Weather Data

Weather data or weather reporting is part of flight operations. ARINC offers the latest weather prediction and reporting services to the aviation industry and airports around the world. ARINC’s Graphic/Text Weather Service (or G/TWS) provides near-real-time graphic and text weather information to flight crew using GLOBALink data link services.

ARINC also provides terminal weather information to aircraft taking off or landing, including precipitation data, gust fronts and wind shear microbursts information within 15 nautical miles of the airport. The ARINC meteorological data collection and reporting system collects real-time weather reports such as wind and severe weather advisories.

Flight Planning

Flight planning is the process of describing a proposed aircraft flight and the flight plans produced typically involves two safety-critical components: fuel calculation and compliance with air traffic control requirements. These components ensure aircrafts can safely reach the proposed destination and to eradicate the mid-air collision risks. Appropriate flight planning also minimises the costs of flights by choosing the optimal route, height and speed; and also by minimum on board fuel load for the proposed journey. Flight planning requires accurate weather forecasts to calculate the impact on fuel consumption due to head or tail winds and air temperature.
