Which component is NOT typically included in an electronic flight bag (EFB)?

The correct response identifies that aircraft maintenance logs are generally not part of an electronic flight bag (EFB). An EFB serves as a digital platform designed to enable pilots and flight crews to access important information that facilitates flight operations. This typically includes charts, operational flight plans, and performance data—each of which directly supports the operational and navigational needs during flight.

Charts provide pilots with necessary visual references for navigation, including en route and terminal area information. Operational flight plans document the specifics of the flight, including routing, estimated times, and fuel requirements, enabling crews to execute flight operations more efficiently. Performance data gives vital metrics about aircraft capabilities under varying conditions, supporting decision-making.

In contrast, aircraft maintenance logs are primarily administrative records that track the maintenance history and status of an aircraft. While crucial for the overall safety and compliance with regulations, these logs are not actively used during flight operations in the same manner as the components typically found within an EFB. Therefore, the distinction lies in the operational functionality of the EFB versus the record-maintenance role of the aircraft maintenance logs.
