Helicopter weight and torque advisory system

Abstract From the Canadian patent

A helicopter weight and torque advisory system for connection to cargo hook load sensors, fuel flow air, temperature and altitude indicating systems of a helicopter. The advisory system provides the flight crew of the helicopter information as to available engine torque, gross weight, gross weight center of gravity condition, and weight supported by each cargo hook as an external sling load is raised and supported by the helicopter. Also information as to required engine torque for maximum helicopter range and endurance performance is provided.
