How long must you wait after engine shutdown before checking tire pressure?

The correct choice is based on the need for safety and accuracy when checking tire pressure on the Super Hornet after engine shutdown. After the engines are turned off, residual heat from the engines can affect the temperature of the tires, which in turn can impact tire pressure readings. Waiting for a period of two hours allows sufficient time for the tires to cool down to a stable temperature, ensuring that the pressure checks are accurate and that safety protocols are adhered to. This time frame helps in minimizing the risks associated with handling hot equipment and ensuring optimal performance and safety of the aircraft when it is in operation.
