Are infants included in their parents' standard mass calculations?

Infants are typically included in standard mass calculations when they do not occupy their own seats on an aircraft. When an infant is held by a parent or guardian, they are considered part of the parent's mass calculation. This practice accounts for the total weight that the parent will be carrying during the flight, which is crucial for weight and balance considerations.

However, if an infant occupies their own seat, they are treated separately. In this case, their weight is individually accounted for in the mass calculations, just like any other passenger. Because of this differentiation, the statement that infants are included in their parents' standard mass calculations only when they do not occupy their own seat is correct. Understanding this distinction is essential for accurate weight management and safety in aviation operations.
