FAA Aircraft Dispatcher (ADX)Regulations (Part 121)Easy
A Part 121 certificate holder operates an airplane with a maximum approved seating capacity of 137 passengers. Under 14 CFR 121.391, what is the minimum number of flight attendants required?
- A5
- B3
- C4
- D2
Show answer & explanationAnswer & explanation
Correct answer: B. 3
Section 121.391 requires at least 2 flight attendants for seating capacities of 51-100, plus one additional flight attendant for each unit (or part of a unit) of 50 passenger seats above 100. With 137 seats, that is 100 + 37 (a partial unit of 50), requiring 2 base attendants + 1 additional = 3 total.
Why the other options are wrong
- A. 5 would require seating well above 200 passengers.
- C. 4 would apply only if seating exceeded 150 passengers.
- D. 2 attendants only satisfies capacities up to 100 seats, not 137.

Memory trick: "One for fifty, two for a hundred, then one more for every fifty you're rockin'."
