Usage Cases Aviation Radio Data Communication Service
Communicating flight plans and various information in an ever-changing environment to support on-time departures
The ACARS system contributes to on-time departures by quickly and reliably transmitting a variety of information, including flight plans, aircraft payloads, and aircraft weight balance. In addition, information essential to operations, such as constantly changing weather and airport information, is sent and received between the ground and aircraft via the ACARS system, helping to ensure safe operations.
Supporting safe flights with rapid data communication between ground and aircraft
The ACARS system continues to support safe and comfortable air travel by transmitting weather conditions at the destination and airport information even while the aircraft is in flight. Weather information observed by the aircraft is also distributed to the ground, helping to ensure safe and comfortable flight operations. It is also used to transmit customer information that requires coordination with ground staff during the flight.
Immediately after landing, the aircraft accompanies the baton relay to the next scheduled flight.
The ACARS system accurately communicates the time an aircraft lands and arrives at the parking lot, supporting the efficient work of all involved in preparing for the next on-time flight. By contributing to predicting arrival times, which vary depending on the runway and parking lot used, the system enables a cross-departmental relay of work for the return flight, such as preparation of ground equipment, refueling, cleaning, and in-flight meal preparation.
Sharing aircraft and engine status with the ground in a timely manner enables prevention of problems before they occur
As aircraft become increasingly digitalized, preventive maintenance to prevent breakdowns before they occur is becoming increasingly important in preventing problems during flights. The ACARS system transmits aircraft and engine data to aircraft and engine manufacturers in a timely manner during flight, helping with predictive maintenance and quality improvement.
Transmitting meteorological data from the sky in real time contributes to improving the accuracy of weather forecasts
The ACARS system transmits data on the atmosphere acquired by sensors installed on aircraft during flight to meteorological agencies in real time, contributing to improving the accuracy of weather forecasts. In addition, the accumulated data is also used for meteorological research and disaster prevention measures.
