Which statement about electronic flight bag (iPad) requirements is accurate?

• A. EFBs shall have same flight application
• B. EFBs must be connected to aircraft power at all times
• C. EFBs cannot be used for weather data
• D. EFBs battery must be exactly 80%

Answer: (A)

Having the same flight application on EFBs is important because it keeps the data and user interface consistent across devices in the cockpit. When both EFBs run the same app, pilots see identical charts, manuals, performance calculations, and weather data, which reduces the chance of mismatched information or confusion during critical tasks like planning, preflight checks, and in-flight operations. This uniformity also simplifies training and data updates, since there’s a single source of truth for the crew.

The other statements don’t fit because the power setup for EFBs isn’t universally fixed to always be connected to aircraft power; many operate on battery power or provide options for both. Weather data is a common and valuable use of EFBs, so saying they can’t be used for weather is incorrect. And there’s no requirement that an EFB’s battery be exactly 80%; battery management focuses on having adequate charge, not a specific fixed percentage.
