  1. Yes, with no formal approval ✔
  2. Only with an FAA permit
  3. Only during daytime VFR

Why: A qualifying EFB may replace its paper equivalent for Part 91 flying. No formal operational approval is required when the pilot follows AC 91-78A.

Huh, didn't know that: Navigation and performance information on the EFB must be current, valid, and checked by the pilot.
