An aircraft instrument for indicating the performance margin of the aircraft during take-off or a go-around phase of flight and for assisting the pilot of the aircraft in responding to a windshear encounter, comprising: (a) flight path angle means for displaying the flight path angle of the aircraft relative to a scale calibrated in degrees; and (b) maximum angle of attack means for displaying relative to said scale and said display of said flight path angle the margin to the maximum permissible angle of attack, said maximum angle of attack means being driven by a Stall Warning System which operates in response to aircraft flight parameters.
