What is the maximum weight for cargo placed on a seat without manufacturer permission?

The correct answer is 77 kg, which is the maximum weight for cargo that can be placed on a passenger seat in an aircraft without the specific permission of the manufacturer. This weight limit is established to ensure safety and compliance with airworthiness standards. Placing cargo above this limit can interfere with the functionality of the seat, potentially endangering passengers and crew in the event of an evacuation or emergency situation.

The reason the other weight options are lower than 77 kg is that they fall outside the standard regulatory limits for cargo secured on a passenger seat, which must be within manageable parameters to prevent injuries and maintain other safety protocols established by aviation authorities.
