For planes with a capacity over 100 passengers, how many flight attendants are required?

The requirement for the number of flight attendants on commercial aircraft is outlined in the relevant Federal Aviation Regulations (FARs), specifically focusing on passenger capacity. For airplanes with a seating capacity of more than 100 passengers, the regulations stipulate that there must be at least two flight attendants, and for every additional fifty passengers beyond that initial one hundred, an additional flight attendant must be added.

This means that if the aircraft has a maximum passenger capacity of 101 to 150, there would still only be two flight attendants required. However, if the capacity increases to 151 passengers, there would need to be three flight attendants and so forth, following the stipulated ratio. This metric ensures sufficient safety and service coverage for larger groups of passengers.

The other options do not align with this regulatory requirement, either specifying incorrect ratios or basing the number of attendants on an inaccurate formula. The correct response adheres strictly to the guidelines established in the FARs, thus ensuring compliance and safety for larger aircraft operations.
