Final answer:
Rapid refueling (hot refueling) is generally not permitted with a patient on board an aircraft due to safety and medical reasons.
Step-by-step explanation:
Rapid refueling, also known as hot refueling, is not typically permitted with a patient on board an aircraft. Rapid refueling involves refueling an aircraft while the engines are still running, which presents safety risks. When a patient is on board, it is important to ensure their safety and minimize any potential hazards, so the aircraft will usually be shut down during the refueling process.
In addition to safety concerns, rapid refueling with a patient on board may also have medical implications. For example, patients who are receiving certain medical treatments such as radiotherapy may have restrictions on exposure to radiation. Therefore, it is important to follow specific protocols and guidelines to protect the health of the patient.
