Problems solved by technology
Although this data transfer can be performed over several airport Wi-Fi or cellular links, the availability of these links is generally limited to larger airports
Additionally, these links tend to be expensive, unreliable in data transfer speeds and connectivity, vulnerable to security breaches, and sometimes lack standardization

Embodiment Construction
[0032] In the following description, various specific details are set forth in order to provide a thorough understanding of the concepts presented. The concepts presented may be practiced without some or all of these specific details. In other instances, well known operations have not been described in detail so as not to unnecessarily obscure the described concepts. While some concepts will be described in conjunction with specific embodiments, it will be understood that these embodiments are not intended to be limiting.
[0033] introduce
[0034] Data transmission between aircraft and external networks, such as airport networks, airline networks and other types of ground networks, is important to modern aviation. Data collected during previous flights may need to be downloaded from the aircraft for processing, while new data needs may need to be uploaded for future flights. Typically, an aircraft has limited time to land and a very large amount of data needs to be commun...

Provided are methods and systems for terrestrial data transmission between aircrafts and external networks, such as airline and / or airport computer systems. When an aircraft is parked at the gate, the aircraft is connected to and powered by an electrical cable, such as a stinger cable. This cable may be also be used for wired data transmission between the aircraft and the gate using broadband over power line (BPL) technology. The gate and the aircraft are each equipped with a BPL module. The aircraft may include other communication modules, such as a Wi-Fi module, a cellular module, and / or an Ethernet module. These other modules can be also used for data transmission in addition to or instead of communication through the BPL module. A communication link manager may be used to select one or more communication modules depending on availability of communication links, costs, speed, and other parameters.
Description
technical field [0001] The present invention relates to data transmission systems, and more particularly to aircraft data transmission systems. Background technique [0002] The amount of software and data stored in and collected by on-board aircraft information systems is rapidly increasing. Airborne information systems use software and data for various cabin systems, avionics systems, and in-flight entertainment systems, among others. Airlines are responsible for updating the data and software on their aircraft and downloading data collected from the aircraft during one or more previous flights and uploading new data in a timely manner. All of these activities require fast data transfer between the aircraft and external networks while the aircraft is on the ground (eg parked at a parking stand). Although this data transfer can be performed over several airport Wi-Fi or cellular links, the availability of these links is generally limited to larger airports. Additionally,...
