How many infant life vests are required in the first overhead bin A/CL according to safety regulations?

The requirement for infant life vests in the first overhead bin A/CL is based on safety regulations that specify the number of infant life vests must accommodate the expected number of infant passengers on board. In commercial aviation, it is standard to require infant life vests for each child under two years of age who does not occupy their own seat.

The regulations tend to stipulate a minimum quantity, which typically correlates with the aircraft's seating configuration and maximum capacity. The option indicating that five infant life vests are required reflects typical policies where airlines are prepared for scenarios involving multiple infants traveling on a flight. This ensures that there are sufficient safety devices for all infants on board, promoting passenger safety during potential emergency situations.

This number is determined by the fact that it's not uncommon for flights to carry several infants, and having a few extra life vests ensures readiness for unforeseen circumstances.
