What is the minimum flight attendant requirement for an aircraft with 50 passengers?

The minimum requirement for flight attendants on an aircraft is governed by safety regulations, which stipulate that airlines must have a certain number of flight attendants based on the passenger capacity of the aircraft. For aircraft with 50 passengers, having one flight attendant is the established safety standard. This regulation ensures that adequate assistance is available in case of an emergency and that passengers are properly cared for during the flight.

In this context, while other options suggest different ratios or no requirement at all, they do not align with the regulatory framework that aims to prioritize passenger safety and operational efficiency. The established guideline emphasizes the critical role of flight attendants in managing passenger safety and comfort, particularly on larger aircraft. Thus, the requirement of one attendant per 50 passengers is the correct answer.
