When should flight attendants make seatbelt announcements?

The correct answer is when the seatbelt sign is turned off or on because this is the protocol that ensures passengers are informed of the safety requirements at critical times during a flight. Flight attendants are trained to make seatbelt announcements at the initiation of specific flight phases such as takeoff, landing, and during turbulence to reinforce safety and the need for seatbelt use.

When the seatbelt sign is illuminated, it indicates to passengers that they should be seated with their seatbelts fastened due to potential changes in the aircraft's movement. Conversely, when the sign is turned off, it signals that passengers may unbuckle their seatbelts. These announcements are essential for maintaining safety and ensuring that all passengers understand when they should be secured in their seats. It is a critical part of the flight crew's responsibility to communicate these necessary actions consistently throughout the flight, not just when aspects like turbulence occur or during takeoff and landing.
