In what phase of the flight can a CARES device be utilized?

The correct choice indicates that a CARES device can be utilized in all phases of flight. This makes sense as the CARES (Child Aviation Restraint System) device is designed for use with children and provides safety and security throughout the entire flight duration.

During takeoff and landing, the device ensures that the child is safely secured in their seat, which is critical during these phases where acceleration and deceleration occur. In addition, while the seatbelt signs are on or off, the device can still play a key role in maintaining the safety of an infant or small child during the cruise phase as well, adapting to different conditions and ensuring that young passengers are not unprotected.

This comprehensive applicability aligns with safety regulations aimed at keeping all passengers safe throughout every aspect of their journey, making the all-phases-of-flight application essential for utilizing the CARES device effectively.
