When lifting with airbags most of the weight of the aircraft is lifted where? | the wings |
What is the formula of figuring the lifting capacity of a lift station? | Bag Surface Area (BS) X Contact Pressure(CP) X Percent of Bag Surface Area (PB) = Lift Capacity (LC) |
What instrument can be used to determine where to start a bag station's cribbing on a high with aircraft? | Plumb Bob |

What is an alternate type of respirator for use in the recovery of composites? | PAPR |
What are the cordon zones at a crash site? | Hot, warm and cold |
Who determines if and when fixant is applied to damaged composites at the crash site? | Investigation authority |
Why is fixant applied to the composite surfaces? | To stop composite dust and fiber ends from becoming airborne |
When cutting composites what hazards should be checked for in the area? | Fuel and oil |
Who determines the proper PPE needed for a composite recovery operation? | Bio-Environmental and environmental management office |
What makes the PAPR suit more desirable to use for the recovery team? | Does not require a fit test and usable for other team members |
