What age range defines a child in aviation safety regulations?

In aviation safety regulations, a child is typically defined as being between 2 to 12 years old. This range is important for understanding the requirements for child safety, such as the use of approved child restraints in aircraft and the rules concerning unaccompanied minors.

The choice of age 2 as the starting point aligns with the guidelines for many airlines regarding when children can begin occupying a separate seat with appropriate safety measures. The upper limit of 12 years is significant because it ensures the regulations cover children who may require different safety considerations than adults and older teenagers.

The other age ranges provided do not accurately define a child in the context of aviation regulations, as they either include ages outside of the recognized limits or do not provide the accepted parameters typically used in this field.
