I am a FAA licensed commercial instrumented rated single engine land air plane pilot with no experiences in any helicopters.
I am under the impression that most helicopters are rated for visual flight rule flying only, which is defined as minimum of 1000 ft. ceilings and 3 mile visibility in all directions, also the rule of at least 1000 Ft clearances, unless landing, in urban area from all people and buildings, this flying rule applies to all certified aircraft including helicopters.
My heart weeps for the families of those that where killed in this accident, including Kobe Bryant family
