Under which condition will a helicopter not be used for transport?

A helicopter will not be used for transport when a patient is combative and cannot be restrained due to safety concerns. In such scenarios, the risk of injury to both the patient and the crew increases significantly. If a patient is unable to be secured properly, they might move unpredictably during flight, which could endanger not only their own safety but also that of the flight crew and transport operation.

In contrast, when a patient is stable and cooperative, as well as when their weight is within the acceptable range, these criteria do not pose the same level of risk, making air transport feasible. Similarly, clear weather conditions are essential for safe helicopter operations, but they do not influence the decision related to patient cooperation and behavior. The decision to use helicopter transport heavily weighs on the patient's ability to be safely managed during transit.
