Why is the preferred heading for the casualty's boat 20 to 40 degrees to the right of the wind? See Student Workbook p103.
1. Heading into the wind at this angle is the most comfortable course for the casualty
2. It isn't. The preferred heading is with the wind 20 to 40 degrees off the port bow.
3. So that the helicopter can fly directly into the wind while giving the pilot and winchman a good view of the boat from their positions on the starboard side of the aircraft.

2. The light line should be made fast on the boat once the winchman is aboard the boat
3. The helicopter winches the load up and down off to one side of the boat
4. The helicopter winches the load up and down directly above the boat
5. The light line is used to guide the load onto the deck, without pulling strongly
6. The light line is used to heave the load aboard by pulling hard on it
