During a hot refueling evolution, how do you precheck a drop tank?

The correct method to precheck a drop tank during a hot refueling evolution is to utilize the external precheck switch located in fuel door 8. This process is essential because the external precheck switch allows the crew to verify the readiness and conditions of the fuel system while ensuring safety during refueling operations. By using this dedicated switch, personnel can confirm that the system is functioning correctly and that there are no issues such as incorrect pressure or leaks, which could pose a hazard during refueling.

This option is particularly relevant in the context of the Super Hornet's operational procedures, where each phase of refueling requires specific checks to ensure that fuel is being handled properly and safely. The focus on using the designated precheck switch highlights the importance of following established protocols and utilizing available tools designed specifically for this task, thereby enhancing safety and efficiency during the hot refueling process.
