[0003] EFB equipment is divided into portable EFB equipment and installed EFB equipment.

[0004] Nowadays, portable EFB equipment is widely used in major airlines, and its main form is an independent tablet computer which is carried and kept by the flight crew. Most of the existing aircraft do not reserve communication interfaces between the core avionics system and the portable EFB equipment when they are designed, so the portable EFB equipment cannot obtain the data of the core avionics system of the aircraft, nor can it send data to the avionics system.

[0005] As an airborne display unit, installed EFB equipment is only available in a few new aircraft models. Moreover, compared with the rapid development of touch screen devices such as mobile phones, tablets and vehicle displays, the hardware performance and functions of the installed EFB equipment of existing aircraft models have been completely outdated, and some installed EFB equipment models still rely on key operation and can only use the built-in applications at the time of factory shipment, without the possibility of functional expansion.

[0006] Moreover, there is no data communication interface between the installed EFB equipment in the cockpit of the existing large passenger aircraft and the portable EFB equipment, so the portable EFB equipment cannot be used in coordination with other equipment in the cockpit. For example, the aeronautical chart software in the portable EFB equipment needs to obtain the real-time latitude and longitude of the aircraft, but it cannot obtain it due to the lack of communication interface; the portable EFB equipment needs to project the display content onto the onboard display, but it also lacks a data transmission channel.
