Hand and Arm Signals Arms crossed and extended downwards in front of the body.

Land

Why should soldiers conducting sling load operations consider wearing their flak jackets?

NOTE: During a sling load operation with an H-53E, all personnel should wear body armor (flak jacket) because of the amount of debris blown by the rotor wash.

Hand and Arm Signals Making a circular motion with right hand overhead ending in a throwing motion in the direction of takeoff. Also means load clear, hookup good.

Takeoff

Why is it important to use a nylon donut/web ring or a reach pendant when attaching the load to the UH-1?

The cargo hook is stationary and using a metal apex with a heavy load would bind on the hook and shear it off.

How far apart are the fore and aft cargo hooks from the center cargo hook?

The fore and aft hooks are approximately 6.5 feet from the center hook.

How would you know if the ground is good enough for a size 1 and 2 aircraft?

The ground is firm enough for size 1 and 2 helicopters if it can support a 1 1/4-ton truck.

What does the hookup man do?

The hookup man positions himself so that the hookup can be accomplished quickly. The hookup team will be in position at the load when the helicopter arrives.The hookup men will then place the apex fitting into the aircraft cargo hook and ensure that the hook is properly closed and locked.

The hookup team consists of what positions?

The hookup team normally consists of three men; the signalman, the static wand man, and the hookup man.

Where should the signal man position himself?

The signalman positions himself upwind of the load facing the load and the aircraft approximately 20 meters in front of the load to be lifted. The signalman positions himself at the aircraft's 10 o'clock position if the aircraft emergency landing procedure is to the right or at the 2 o'clock position if the aircraft emergency landing procedure is to the left.

Who selects and prepares landing sites?

The supported or receiving unit commander, in coordination with the aviation liaison officer, if available, selects and prepares the landing sites.

During the day, how do you determine unusable LZ area from obstacles? During the night, how do you determine unusable LZ area from obstacles?

To determine the UNUSABLE, use the 10:1 ratio rule for day. To determine the UNUSABLE, use the 14:1 ratio rule for day.

True or False? Always attempt to land an aircraft into a head wind.

True

True or False? The signalman maintains visual contact with the pilot controlling the aircraft at all times throughout the hookup.

True

What are the rules of the APEX?

UH-1 needs Type26 3ft 2 Loop for both sling sets due to rigid cargo hook. H60 needs the apex for the 10k sling set, but not the 25k sling set. CH-47 needs the apex for the 10k sling set, but the 25k apex is optional.

How would you go about cleaning the sling sets?

Wash with warm soapy water making sure to get rid of any corrosion, and then air dry. Keep out of sunlight.
