Answer
The pilot should plan for low level helicopter activity, keep a strong lookout, choose a route that can be cleared quickly, and land or move away if helicopter activity appears. Local heliport or hospital flight procedures should be checked where official information is available.
Explanation
Helicopter risk is often local and low level. A flight can be outside a major airport zone but still conflict with medical, police, rescue, utility, or private heliport traffic. The plan must account for the traffic that actually uses the airspace.
