Abstract
Provided are methods and systems for terrestrial data transmission between aircraft and external networks, such as airline networks and/or airport networks. While an aircraft is landed, various data domains may need to be transmitted between the aircraft and such networks using two or more communication channels available to the aircraft. These channels may include wired and/or wireless channels, such as broadband over power line channels, Ethernet channels, Wi-Fi channels, and cellular channels. The available communication channels are allocated to transmit particular data domains based on the security levels of these channels. For example, aircraft control domains may be transmitted using a more secure communication channel than passenger information domains and/or entertainment systems domains. In some embodiments, multiple communication channels may be used to transmit the same domain parsed into multiple transmission packets. The packets are recombined back into the data domain after the transmission.
