Careful and accurate placement of avionics boxes during maintenance of flight hardware

Because a key driver to the cost of launching aerospace hardware into space is its weight, the design of the flight hardware has many trade-offs to reduce the overall weight of the flight vehicle. These trade-offs usually result in reduced work space for maintaining and repairing the flight hardware. One very common ground replaceable flight hardware in aerospace launch and crewed vehicles are the avionics box. Which during the installation of these avionics boxes they must be accurately and carefully placed to reduce damage to hardware, such as the cold plate, wiring, etc. The focus of this paper is to describe the results of a study set out to determine how accurately and carefully a human can place an avionics box in restricted space.
