The Sky-Weigh external load monitoring system provides safety and efficiency for medium to heavy lift helicopters.
MSI is best known in the rotary aviation industry for the design and manufacture of helicopter cargo hook load monitoring equipment. The company is recognized as the primary, and often the only, source for these unique systems.
The MSI-150 Sky-Weigh is composed of a specially designed load sensor that interfaces directly with your aircraft's cargo hook. Via an interface cable, a panel-mounted digital indicator continuously displays the load weight slung to the cargo hook. The Sky-Weigh eliminates guesswork of unknown loads to provide safety and efficiency.
MSI equipment has been installed throughout the world on both military and commercial helicopters. With system offerings for more than twenty aircraft models, MSI's selection is by far the most comprehensive. Best of all, Sky-Weigh systems are totally electronic and pre-qualified to ensure optimum accuracy and reliability.
MSI is FAA/PMA authorized and maintains quality assurance under Standards MIL-45208 and MIL-Q-9858A.
