You Need an Electronic Flight Bag

The AC defines an EFB as an electronic display system intended mainly for cabin or cockpit use. To that end, an EFB can display aviation data such as charts and make basic calculations such as time, fuel and distance calculations. An EFB can also include other databases, perhaps FARs, or additional applications such as crosswind, weight-and-balance and holding calculators.

Key Takeaways:

The FAA's AC 91-78 guides Part 91 pilots on safely transitioning from paper charts to Electronic Flight Bags (EFBs), distinguishing between Class 1 (portable) and Class 2 (mounted) devices with specific rules for each.
EFBs can replace most paper aeronautical charts and operational documents across all flight phases, provided the displayed information is current and valid, but cannot substitute for required aircraft systems or physical pilot/aircraft certificates.
Pilots are responsible for ensuring EFB data is always up-to-date, understanding device functions, confirming proper installation and power for mounted units, and having backup plans in case of EFB malfunction or failure.

You use a tablet in the airplane, right? You’ve probably got one of the popular apps like ForeFlight, Garmin Pilot, or WingX. You probably use it for charts and nav, but if you don’t use your tablet as a full electronic flight bag (EFB), you might be missing the boat.

Check the Advisory Circular

Back in 2007, the FAA issued AC 91-78, Use of Class 1 or Class 2 Electronic Flight Bag (EFB). Not only did the AC define an EFB, it also created regulatory distinctions and discrete rules governing Class 1 portable and Class 2 mounted EFBs. The AC gives Part 91 pilots guidance on how to safely transition from paper aeronautical charts and other cockpit documentation and replace it with an Electronic Flight Bag.
