SECTION 9. MISSION EQUIPMENT

Figure 1: S-61R Hoist System

1 Rescue Hoist

1.1 Overview

The S-61R is equipped with a rescue hoist mounted above 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 no load and 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

1.2.1 Load Types

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.
1.2.2 Deploying

A load is generally deployed by clicking on it. For the rope and the harness, you can click on one of the bags in the storage area near the cabin door. The smaller yellow bag contains the harness, while the larger orange bag contains the rope. The rescue basket, stokes basket and forest penetrator are configured as a sit target as its default touch action, so a simple left click will result in sitting on that piece of equipment. If it is necessary to deploy rescue equipment while not sitting in the helicopter you can right click on it and select "Touch". If other rescue equipment is already deployed, the selected equipment will be swapped into the helicopter before the new equipment is swapped out. Clicking on the hook, will swap in all equipment. No more than 1m of cable should be deployed when swapping loads/out.

For the stokes basket and rescue basket, if anyone is sitting in them when they are swapped in our out, the avatar will be moved in or out with the load. For the forest penetrator and harness, however, it is necessary for the avatar to move into OnBoard by clicking on the floor of the main cabin before swapping in the penetrator. Failure to do so, will result in the avatar being unsat while outside the helicopter, potentially leading to serious injury or death.

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

Figure 2: Pilot Winch Controls
Figure 3: Crew Winch Controls
1.3.1 Pilot Control

To use the pilot winch controls (see Figure 2), the HOIST MASTER switch on the upper panel must be set to PILOT. The hoist control panel, located on the lower consoled, consists of a single three-position rocker switch with UP, DOWN and a center HOLD position. The switch is spring loaded to the HOLD position.

A pilot hoist shear switch is located on the upper console. This switch can be used in the event the cable becomes entangled and must be cut free to ensure the safety of the helicopter. The switch has a guard which must be opened before activating the switch. The shear switch is active regardless of the position of the HOIST MASTER.

1.3.2 Crew Control

The crew winch controls (see Figure 3) are located to the right of the main cabin door. The HOIST MASTER switch on the upper panel must be set to CREW position to utilize them. The main control is a lever that can be tilted to the left or right to lower or raise the winch. The amount by which the lever is tilted will affect the speed of the winch.

The crew member occupying the hoist operator seat (kneeling by the main door), can also use key controls to control the winch. Use PgDown to lower the winch, and PgUp to raise it. These controls are only active when the hoist is in crew mode.

A crew hoist shear switch is located above and to the right of the hoist control. It is covered by a switch guard which must be opened to activate the shear. The shear panel also includes a shear test switch. To test the shear switch, first set the shear test switch to TEST. Then open and activate the shear switch. If the green test light comes on, then the shear circuitry is operating correctly. Be sure to turn off the shear switch and close the guard before turning off the test switch.

1.3.3 HUD Control
Figure 4: S61 Winch HUD

The winch HUD (see Figure 4) can be used to control the winch by any crew member in the the helicopter. In order for the HUD to be active, the helicopter must have hydraulic and electrical power, and the HOIST MASTER must be in the CREW position. The winch HUD has two buttons on the left side to raise and lower the winch. A digital display shows the current cable length and the current height above the ground. A dial on the right-hand side sets the winch speed. Finally an emergency cable cut button with a guard is located on the top portion of the HUD.

1.3.4 Winch Chat Commands

The winch can also be controlled through the chat commands. The HOIST MASTER must be set to CREW in order to use the chat commands. The available commands are:

Command Description
w n Move which so that n meters of cable are deployed.
w u n Move which up by n meters.
w d n Move which down by n meters.
w cut Cut the cable.
w + Increase winch speed (by chat)
w - Decrease winch speed (by chat)
w x Stow all hook loads
w b Deploy the rescue basket
w s Deploy the stokes basket
w h Deploy the harness
w sh Deploy the harness
w p Deploy the forest penetrator
w r Deploy the rope

1.4 Rappelling Rope

Unlike the baskets and harness, the rope attaches to a ring on the back of the winch. The rope can be used to quickly egress from the helicopter in a high hover to the surface. Click on the orange rope bag to deploy the rope.

Any passenger in the main cabin may use the rope by clicking on the rope or the winch body. This will position the user at the top of the rope in a rappelling pose. Use the down arrow to control descent. Once at the bottom, the user will automatically unsit from the rope and aircraft.

1.5 Hover Trim Control

Figure 5: Hover Trim Controls

The hoist operator station also includes a hover trim control (see Figure 5). This can be used by the hoist operator to control the helicopter position while using the hoist. Click near the control to move the lever and cause the helicopter to translate its position at about 1 m/s. The hover trim system operates by applying a small bias to AFCS. The AFCS must be on and in an active hover in order to use the trim control. It is also possible for the hoist operator to use arrow keys to control the hover trim.

1.6 Hoist Limits

Operating Limits

  • Duty Cycle: Continuous
  • Maximum load: 300 pounds lowering, 600 pounds raising
  • Maximum Airspeed with Hoist Cable Extended: 50 kias

2 Medical Equipment

Figure 6: Medical Bay

The S-61R is equipped with two medical bays on the left side of the cabin. The upper bay is a litter (see Figure 6). For the lower bay uses the stokes basket when it had not been deployed for rescue purposes. The bays are similarly equipped, but share an EKG and defibrillator unit. Each bay includes oxygen and a hook for starting an IV. The patient's medical state is affected by how the various equipment is used.

2.1 Patient Health State

Patients in the medical bay can be in one of the following five states:

State Description
Normal No obvious medical issues. However, all patients should be observed for possible signs of distress or deteriorating conditions. Patients in this state will have a normal hearth rhythm.
Distress Patient is in distress of some kind whether pain or shock. Patients in this state may have an elevated and/or irregular heart rate.
AFib Atrial fibrillation is a quivering or irregular heartbeat.
VFib Ventricular fibrillation is a rapid, life-threatening heart rhythm starting in the bottom chambers of the heart.
Flatline No heartbeat at all.

The state of a patient can change over time either for the better or for the worse. The medical procedures applied to the patient will affect the outcome. Newly rescued patients are typically in the distressed state.

The health of a patient can be set manually by either the patient or the crew through a menu for RP purposes. The menu is accessed by clicking on the litter or stokes basket in which the patient is laying. Choose HEALTH from the menu then select the desired health state.

2.2 Patient Bay Management

You can also swap the patients that are in each bay. The stokes basket must be stowed and inside the helicopter in order to swap. Click either the litter or the stokes basket to get the menu, then select SWAP. Patients in the litter and stokes basket will then swap positions. The health states of each patient will be preserved when swapping positions.

The patient may also exit a medical bay by clicking on the floor of the helicopter cabin. This move the patient into the OnBoard system. See SECTION 12. SL Features for more details on how to use OnBoard.
