What restrictions apply to carrying cargo on a control seat?

The correct response highlights that when it comes to carrying cargo on a control seat, there is a specific weight limit of 77 kg. Moreover, it's essential that this cargo is properly restrained. This requirement is in place to ensure that the cargo does not interfere with the operation of the controls or safety of the aircraft. Restraining the cargo prevents it from moving unexpectedly, which could jeopardize the pilot's ability to operate the aircraft effectively. These regulations are crucial for maintaining safety standards in aviation operations, especially during flight when any distraction or obstruction could lead to hazardous situations.

In summary, the regulation establishes a clear weight limit and ensures that anything stowed on control seats is secured, maintaining the integrity of flight operations.
