When planning for emergency use of MASS, what should be ensured?

When planning for emergency use of a Mobile Aviation Support System (MASS), ensuring the usable portion of the runway is critical because it directly impacts the safety and efficiency of operations. A usable runway must be free from obstacles and in good condition to accommodate takeoff and landing. This includes assessing the length and surface integrity of the section of the runway that will be utilized, as any degradation or obstruction can significantly hinder aircraft operations during an emergency.

The usable portion encompasses factors such as necessary dimensions for the type of aircraft in use, ensuring proper maneuverability, and adherence to safety regulations. This aspect guarantees that any emergency response or operation involving the MASS can be executed without additional risks that could arise from runway inadequacies. Therefore, focusing on the usable runway portion is essential to the successful deployment of emergency operations involving MASS.
