As the helicopter reaches the vicinity of the load he will use hand and arm signals to positionthe cargo hook of the aircraft directly over the load and close enough to the load so that the hookup men will be able to place the apex fitting onto the cargo hook. During this time it is critical that the signalman position himself so that the pilot can easily view his signals. Since the pilot of an Army aircraft is located on the aircraft's right side, the signalman will usually be located slightly to the aircraft's right. If terrain in the area forces him to place himself elsewhere, he must ensure that he is in the pilot's view at all times, regardless of where he is positioned.
