An electronic flight bag (EFB) system for use on a mobile platform, for example, a commercial or military aircraft. The EFB system includes first and second independent processors that run first and second independent software applications. The first software application may be a Type C application requiring a high level of governmental agency certification for use on an aircraft while the second application may be a commercially available, off-the-shelf software application that requires no certification. The two processors share a common display, although the first processor is provided with control over the display so that use of the display by the second processor can be inhibited or limited by the first processor as may be needed to display more critical flight or aircraft related information. The first processor is also provided with control over a switching subsystem that can interrupt the flow of information from external I/O devices to and from the second processor, if needed.

A flight kit having a process and set of software tools for: marking up and restructuring of flight information content such as manuals, checklists, aerodynamic data, and alerting information; converting and storing this content in an electronic form; dynamically generating a user interface based on the specific data; and delivering this to a flight crew. The flight kit can provide remote data updates and management of flight kit applications via Internet connectivity.

An electronic flight bag providing computational services for an aircraft and communicating with aircraft avionics may execute aircraft-design-approved Type-C applications together with non-design-approved Type-A/B on a single processor through specific modifications of the operating system to control memory and processor access thereby providing isolation comparable to that of dual processor systems in which the Type-C applications and Type-A/B applications are executed on different processors.
