What is the function of an Electronic Flight Bag?

The function of an Electronic Flight Bag (EFB) primarily revolves around its role as a modern, electronic version of a pilot's traditional flight bag. It consolidates a variety of flight-related documents and information that pilots need for planning and executing flights. This can include navigational charts, flight manuals, checklists, operating procedures, and other important operational data.

With the integration of technology, an EFB enhances efficiency and reduces the physical burden of carrying extensive paper documents. It allows for easier updates and access to the latest information. By transforming the way pilots access critical information, the EFB contributes to a more streamlined and safer flying experience, which is essential for modern aviation operations.

The other choices highlight functions that can be part of general aviation operations but do not specifically address the core purpose of an EFB. Traditional flight instruments and tracking flight hours serve different operational roles, while monitoring weather conditions could be part of various onboard systems but is not the direct function of an EFB itself.
