Can the Pilot See YOU ?
From the ground it is easy to see the helicopter at all times. But what about the pilot ? The pilot has only a small window in the floor just enough to see the cargo below the helicopter. Therefore it is very important that you always think of the pilot also must see if you when doing hand signals. Remember when load is hooked on or remotely triggered , the pilot is watching down through the floor window and do not see you even if you see the pilot. Large and overdone arm movements are necessary for the pilot to see and understand what you mean.
