What does EFB stand for and how is it used?

• A. Electronic Flight Bag; an onboard system for weather radar and navigation
• B. Electronic Flight Bag; a handheld notes device
• C. Electronic Flight Bag; tablet-based tool for charts, performance data, and flight planning
• D. Electronic Flight Bag; an onboard entertainment interface

Answer: (C)

Electronic Flight Bag stands for Electronic Flight Bag, and it’s a tablet-based tool pilots use to access digital charts, performance data, and flight planning resources. Rather than carrying paper charts and manuals, crews load enroute and approach charts, airport diagrams, and performance calculations into the device. It also handles weight and balance data, takeoff and landing performance, and flight planning tasks, sometimes including weather briefings andNOTAMs via apps. This setup keeps data current, reduces paper, and streamlines decision-making during flight. It isn’t primarily an onboard weather radar or an entertainment interface, and while it can be portable in some configurations, its main role is providing charts, performance data, and planning tools.
