FAA Aircraft Dispatcher (ADX)Regulations (Part 121)Hard
A Part 121 certificate holder is configuring a new airplane type with 105 passenger seats. Under 14 CFR 121.313, how many megaphones are required on board this aircraft?
- ATwo megaphones.
- BThree megaphones.
- CFour megaphones.
- DOne megaphone.
Show answer & explanationAnswer & explanation
Correct answer: A. Two megaphones.
14 CFR 121.313(b)(1) states that for passenger-carrying airplanes with a seating capacity of more than 60 and less than 100 passengers, one megaphone is required. For airplanes with a seating capacity of 100 or more passengers, two megaphones are required. Since the aircraft has 105 seats, it falls into the '100 or more' category, requiring two megaphones.
Why the other options are wrong
- B. Three megaphones are not a standard requirement under this regulation for this seating capacity.
- C. Four megaphones are not a standard requirement under this regulation for this seating capacity.
- D. One megaphone is required for 61-99 seats, not 105 seats.
Megaphone Requirement (121.313)
Specifies the minimum number of megaphones required on Part 121 passenger-carrying aircraft, based on seating capacity, for emergency communication.
- Not required for less than 61 seats.
- One megaphone for 61-99 seats.
- Two megaphones for 100 or more seats.
Memory trick: Megaphone Rule: 'M' for Megaphone, 'R' for Required. 'Sixty' to 'Ninety-Nine' is 'One', 'Hundred' or 'More' is 'Two'.
