Which of the following is NOT typically considered a minimum equipment requirement for an aircraft?

Inflatable life rafts are not typically classified as a minimum equipment requirement for all types of aircraft. While they are essential safety equipment for aircraft that operate over water or in areas where ditching may be a consideration, they are not a universal requirement across all flight operations. Instead, a minimum equipment list (MEL) generally includes elements that ensure basic functionality and safety of the aircraft, such as seating for each person, visible instruments for operation and navigation, and safety belts for each occupant to ensure their safety during flight.

In contrast, seating for each individual on board ensures that passengers have a designated space, visible instruments are crucial for pilots to monitor the aircraft's status and performance, and safety belts are vital for securing occupants during turbulence or emergency landings. Therefore, inflatable life rafts are considered situational equipment rather than a baseline requirement across all operational scenarios.
