Abstract : Black Hawk and Seahawk helicopters have various fixed physical control limits situated throughout the control system. The range of each pilot control is variable and depends on which limit is reached first. This is a function of the pilot control inputs applied, together with any additional control inputs provided by the automatic flight control system. A procedure has been developed to monitor controls in the vicinity of each limit, and determine if any part of the control system approaches to within a prescribed amount of a limit. Warning lights in the cockpit inform the pilot if a limit is being approached The procedure effectively during a First of Class Flight Trial involving a Black Hawk.
