The analysis of large amount of sensor data can enhance aircraft operations and maintenance. In contrast to other use cases, aircraft sensor data are accumulated on-board during the flight. The data need to be transferred in a short time while the aircraft is on the ground due to limited and expensive connectivity in the air. This leads to a massive transfer of data in a short time. Therefore, we analyze the data rate demand per aircraft in terms of generated data per flight hour. We determine the influence of different parameters on the needed data rate per aircraft. We conclude that the needed data rates are feasible if the full day is used for transmitting. We show that multiple terabyte of generated data per flight hour can be supported by 5G data rates. Furthermore, we highlight challenges for the deployment of an aircraft data transfer system.

往返飞机的大规模数据传输：可行性和挑战

对大量传感器数据的分析可以增强飞机的运营和维护。与其他用例相反，飞机传感器数据是在飞行过程中在机上累积的。由于空中连接受限且价格昂贵，因此需要在飞机处于地面上时在短时间内传输数据。这导致在短时间内大量传输数据。因此，我们根据每飞行小时生成的数据来分析每架飞机的数据速率需求。我们确定不同参数对每架飞机所需数据速率的影响。我们得出结论，如果将整天用于传输，则所需的数据速率是可行的。我们显示5G数据速率可以支持每个飞行小时数TB的生成数据。此外，
