S-61R Pelican/Mission Equipment

SECTION 9. MISSION EQUIPMENT

1 Rescue Hoist

1.1 Overview

The S-61R is equipped with a rescue hoist mounted in front of the main cabin door. The hoist is powered by the utility hydraulic system with control circuits powered by the DC bus. A switch on the overhead panel labeled HOIST MASTER has positions CREW, OFF and PILOT to disabled the system, or give control the either the pilot or the crew. When the winch is not in use, it is recommended that it be kept in the fully retracted position with the HOIST MASTER in the OFF position. This will disable the timer loop in the hoist script and reduce script lag.

1.2 Hoist Loads

The hoist is capable of being used with the following loads:

Device	Use
Harness	Used for deployment and retrieval of rescuers only. Never to be used for patients
Rescue Basket	Used for the rescue of uninjured or lightly injured patients. May also be used for the deployment and retrieval of divers or rescuers not trained in hoist operations. Do not use for patients with suspected back injuries or broken bones.
Stokes Basket	Used for the rescue of injured patients, may be used in conjunction with the harness to allow a rescuer to attend to the patient during the hoisting process
Forest Penetrator	Used for the rapid rescue of uninjured or lightly injured patients, particularly through thick forest cover. Do not use for patients with suspected back injuries.
Rope	Used for the deployment of rescuers by rappelling. This is the preferred method of deployment on land or onto objects such as boats as the rescuer can control their own descent, which increases safety. It is also faster than lowering by hoist.

1.3 Hoist Operation

Warning: Due to SL physics limitations, the hoist loads must be kept at least 1 meter from any solid object or surface, failure to do so will endanger the aircraft

1.4 Hoist Limits
