ABSTRACT:
A power situation indicator configured to provide power information in a rotorcraft is presented. The power situation indicator includes a detection unit configured to detect a current value of each of a plurality of control parameters, each of the plurality of control parameters including a pre-determined operating limit; a calculation unit configured to normalize on a common power scale (a) the current value and (b) the pre-determined operating limit of each of the plurality of control parameters, and a display unit configured to dynamically display on the common power scale a first moveable indicator and a second moveable indicator. The first moveable indicator is driven by one of the plurality of control parameters having the highest normalized current value and the second moveable indicator is driven by one of the plurality of control parameters having its normalized current value that is the closest to its corresponding normalized pre-determined operating limit.
