During which phases of flight can the PM use their EFB if the securing device is broken?

The correct response highlights that the Pilot Monitoring (PM) is allowed to use their Electronic Flight Bag (EFB) only during non-critical phases of flight when the securing device is broken. This is aligned with safety protocols and operational guidelines, which prioritize safety during critical phases of flight such as takeoff and landing, where pilot duties require full attention and hands-on management of the aircraft.

During non-critical phases, like cruising or taxiing, pilots have more flexibility to manage their workload. However, it is important to note that the use of an EFB without a securing device can create distractions or hazards during critical flight operations. Therefore, while the EFB can assist pilots in non-critical situations, the potential risks associated with its use in critical phases necessitate restrictions.

Ultimately, operational best practices ensure that any use of an EFB under these circumstances is carefully evaluated against the need to maintain situational awareness and prioritize safety.
